1969 Camaro Transforms From Big Block to Supercharged LT4 V8 at V8 Speed & Resto Shop


https://static1.pt-content.com/images/pt/2018/02/1969_Camaro_LA_101816_0066JPG-1.jpg


This is the next chapter of the 1969 Camaro we modified in the V8 Speed & Resto Shop with all new Detroit Speed suspension, Forgeline Wheels, Baer Brakes, Toyo Tires, Holley EFI, and more go-fast and handling goodies. Here’s the original forum thread telling that part of the story:


ProTouring.com: https://goo.gl/m9eL6v


And the video from that experience:


https://youtu.be/LlJ3yb0MqR8


Well, remember how we said that some cars are never finished, and are on a constant evolution to improve? WELL, this ‘69 is back in the shop for some upgrades once again!


This time, the owner wanted to change the personality of the car a bit and move from the angry 540 Big Block Chevy into an LT4 supercharged power plant for a more refined - but still powerful - driving experience.


We started the engine removal process by protecting the car with a Badass Fender Cover… which should be called a nose cone, to be honest.


https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_080917_0004aJPG-1.jpg


We measured the spacing on the hood to fenders and valance for reference, and then removed the hood. All the engine fluids were drained, exhaust was disconnected, wiring harnesses disconnected… all the usual items required for engine removal. Out came the big Chevy engine.

Tyler experiences DejaVu on this car, recalling the first time the engine came out of the car before the big suspension overhaul!

The Chevrolet Performance LT4 V8 engine arrived on a pallet from another shop, where it had been painted black and upfitted with an underdrive pulley system to generate more supercharger boost pressure. The dry sump oil system tank is also visible on the pallet in this shot.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_121917_0001JPG-1.jpg

These generate around 640 horsepower and 630 lb. ft. of torque, but the mods on this one will ensure more oomph than that.

The LT4 features direct-injection, and it comes in the Z06 Corvette in regular production trim.

Here the Drive Junky LT4 front accessory system is visible.

Wow, that is a beautiful car and an awesome powerplant! Going with a manual or auto trans?

Wow, that is a beautiful car and an awesome powerplant! Going with a manual or auto trans?

Thanks! It's a T56 Magnum 6-speed in the car. You can see more of it in our previous thread here: https://goo.gl/m9eL6v

Time for a quick test-fit of the LT4.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122017_0025JPG-1.jpg

We had recently installed a new Centerforce DYAD clutch and flywheel on our 540 big block Chevy engine but we wanted to run a Centerforce DYAD clutch with the LT engine as well. However, the LT flywheel would be different. Rather than install the new flywheel with a used clutch and split up the set, we elected to obtain a new flywheel and DYAD DS clutch from Centerforce for the LT engine, and offer the matched clutch and flywheel from the big block for sale.

https://static1.pt-content.com/images/pt/2018/02/ctf046148441_lg-1.jpg

The Centerforce DYAD DS is a thing of mechanical beauty. The machined flywheel is nearly too nice to hide inside a bellhousing!

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122017_0031JPG-1.jpg

BUT… it wouldn’t do much good on the bench! ARP hardware holds it to the LT4 crank.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122017_0032JPG-1.jpg

You’ll notice some pink / red dots on the components… these are alignment markings provided by Centerforce. This system was balanced at the factory, and they are kind enough to place the parts in the box all ready to go. However, if you seperate them, you can realign the parts using the dots to during installation so they remain in balance.

The DYAD part… the 11” clutch disc and the “floater” dual disc assembly. Centerforce claims these will hang on to up to 1300 lb. ft. of torque while still being able to drive comfortably. We’ve found the driveablility claim to be true in several high-hp cars, including this one with the 540. These units provide predictable “grab” with smooth engagement and a pedal you can live with.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122017_0030JPG-1.jpg

The pressure plate and clutch plates mounted to the LT4 with ARP studs. The alignment tool is still in place in this shot. The pink dots correspond with the dot on the flywheel. The cad-plated ring is the front half of the explosion-proof scattershield.

We lowered the LT4 into the nose of the Camaro and shot a quick video. Excuse the quality, this is from a V8TV “Minute To Winnit Live” video we streamed on our Facebook page.

Pics of the fit and some new surprises next time!

[minendrews68]

Nice! Man, I'd like to have that motor and trans setup.

[oestek]

There are numerous connections off the back of the LT4 that require some space to access and make them look clean, as well as for serviceability.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_010318_0005JPG-1.jpg

The V8 crew lowered the engine into the bay just to get a visual of how things were going to fit. This car had a smoothed firewall, and A/C bulkhead fittings down on the passenger side. The motor mounts had not yet been chosen, this was just to get a bird’s eye view of any potential challenges.

https://static1.pt-content.com/images/pt/2018/02/1969_Camaro_LA_20171220z1-1.jpg

It was obvious that there would be some clearance issues on the back side of engine as the assembly moved closer to the transmission.

https://static1.pt-content.com/images/pt/2018/02/1969_Camaro_LA_20171220z2-1.jpg

https://static1.pt-content.com/images/pt/2018/02/1969_Camaro_LA_20171220z3-1.jpg


The engine was lifted out, and the firewall was examined. At this point, the team noticed that the existing firewall was showing some cracking bodywork and would require a fix and repaint regardless.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122217_0060JPG-1.jpg

The decision was made to modify the firewall to better accommodate the new engine and fix the surface issues. In order to do this, the front sheetmetal was to be removed.

- - - Updated - - -

The team carefully measured and recorded the gaps, spacing, and fitment of the panels and the alignment so that everything would go back together properly.

Front body panels removed.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122217_0002JPG-1.jpg

Here you can see the bruised firewall. We decided to investigate further.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122617_0008JPG-1.jpg

Hmm

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122817_0002JPG-1.jpg

Lots of cracks and filler are lurking below…

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_122817_0003JPG-1.jpg

Putting the engine back in place on Dirty Dingo mounts in the Detroit Speed subframe, we could see the clearance from the head to firewall was a bight tight.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_010318_0020JPG-1.jpg

The accessory drive seemed to fit well, even with the increased diameter crank pulley.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_010318_0017JPG-1.jpg

There’s room for the A/C compressor as well.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_010318_0018JPG-1.jpg

But the decision was made to do some work on the firewall to repair the damage and make a bit more room for the engine, as well as to clean up the A/C bulkhead fitting holes.

[oestek]

The Camaro was moved to the metal fabrication shop where the new firewall would be created.

Once the heater block off panel was removed, it became obvious that this car was originally painted blue. It was also obvious that because of the cracks and previous finish work, the heater block off panel was holding water and rusting the bottom of the firewall. Water literally ran out when we removed the panel.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_011618_0001JPG-1.jpg


https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_011618_0002JPG-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_011618_0016JPG-1.jpg

The opening was ground smooth of rust and corrosion and a plan was made for the new firewall.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_011618_0019JPG-1.jpg

Fabricator John felt a large piece would allow him to start over cleanly.

Stomping the steel on the Mittler Brothers shear…

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180002-1.jpg

A little trim to bring it to the firewall…

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180004-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180005-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801170013JPG-1.jpg

And off to the Mittler Brothers bead roller to add some strength and interest to the panel. John likes to draw out the pattern with a sharpie marker and “trace” it with the roller.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180009-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180010-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180011-1.jpg

Keep in mind that with each contour, the panel’s overall size shrinks, so careful consideration needs to be given to the size along the way.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180012-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180014-1.jpg

Quick test… looking good!

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180015-1.jpg

[oestek]

The edges are tapped over with a tee-shaped rounding dolley.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180018-1.jpg

Some shrinking helps tighten up the edges

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180019-1.jpg

The main piece seems to fit pretty well. Next, the tunnel portion is marked for an extension piece on the firewall. This will allow more clearance for the LT4.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180020-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180020JPG-1.jpg

A trip to the Pullmax starts the tunnel housing extension. A pointed die begins to “fold” a flat section.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180024-1.jpg

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180023-1.jpg

The shape is roughed in.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180025-1.jpg

[oestek]

Some shrinking on the Mittler Brothers shrinker helps form the curves

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180026-1.jpg

And a bit more on the Pullmax to make the contours deeper.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180027-1.jpg

And the corners are tightened up with a sharp-edged dolley.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801180028-1.jpg

A test fit with magnets and cleco clamps, things are looking good!

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801190002aJPG-1.jpg

The section is tack welded to the firewall with the HTP Mig 200 welder, then test fit in the car.

The firewall is cut back a bit to facilitate the install of the new panel.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801220001aJPG-1.jpg

The welding is completed and metal-finished, then the panel is cleaned and treated with an epoxy primer on the inside.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801220005aJPG-1.jpg

Any corrosion is removed from the firewall, and weld-through primer is applied before the new panel is welded in place.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801230001JPG-1.jpg

The firewall is then welded to the car, and all welds are finished.

Welds are all ground and metal finished.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201801240016JPG-1.jpg

The finished firewall will only require a touch of filler before epoxy and paint.

The LT4 is lowered back in place, and the fit is verified. It’s still a bit tight, and the harness will need to be held upward during install to fit cleanly in the new panel’s recess.

That's some impressive metalworking right there. I've done enough little fab projects to know how much time and effort goes into something like that. I am also still amazed at the high dollar "parts" cars that still have what appears to be cut corners.

[ryeguy2006a]

Wow, that firewall is awesome!!

You never really know what's under the paint until you strip the whole thing, that's for sure!


Wow, that firewall is awesome!!

Thanks! We think it's more fitting for a car like this.

The Drive Junkie is a sweet set up.

I learned a whole bunch buying a "Finished" Car. There is truly a difference between a "Body" man and a "Fabricator". Having everything metal finished is the way to go. Some of the things we found just made you shake your head in disbelief. Fortunately, I got into the car at a reasonable price and had some room to work. The folks at V8SR have done an outstanding job with my car and I am looking forward to the finished product.

The LT4 runs a dry sump oiling system, meaning it does not have traditional oil pan holding the engine oil supply. Instead, the oil is stored in a seperate tank outside the engine and is pumped through the engine. The benefit is more consistent oil delivery during high speed turns and increased oil cooling and capacity. Also, the pump is more efficient and easier to service than a traditional oil pump.

The down side is the need for complex plumbing and an oil reservoir tank under the hood. Also, it can be challenging to bring the engine oil up to operating temperature in daily-driving conditions thanks to the higher capacity and cooling effects of remote tanks and plumbing.

Locating the tank can be tricky, as one must consider packaging under the hood. In a race car, you ideally want the tank to be “inside” the wheelbase of the car where you can place it to compliment the vehicle’s balance. However, packaging compromises can dictate otherwise.

In our case, we elected to install the custom Peterson Fluid Systems tank in the forward part of the passenger fender.

https://static1.pt-content.com/images/pt/2018/02/19692BCamaro2BLA_201802220007JPG-1.jpg

The footprint of our tank is 7” in diameter. We cut a hole in the inner fender to accommodate the tank.

Note that this Camaro has an RS grille and hidden headlights, so we’ll have to address the light mechanism as we go.

We made an aluminum bracket to mount the tank retaining clamp.

Meanwhile, the crew did some bodywork on the custom firewall and prepped it for paint. A gray coat of epoxy provides corrosion protection.

It didn’t need much, but we skim-coated the panel with Evercoat Ultra filler and blocked it flat as can be.

https://static1.pt-content.com/images/pt/2018/03/19692BCamaro2BLA_201803060015JPG-1.jpg

https://static1.pt-content.com/images/pt/2018/03/19692BCamaro2BLA_201803060016JPG-1.jpg

After filler, the panel was sprayed with a polyester filler, and block sanded some more.

https://static1.pt-content.com/images/pt/2018/03/19692BCamaro2BLA_201803080019JPG-1.jpg

The polyester is blocked until flat, removing any sanding scratches or marks left from the previous steps. It is sanded to 220 grit, and then brought back to the booth for some 2k high-build primer and more block sanding.

https://static1.pt-content.com/images/pt/2018/03/19692BCamaro2BLA_201803080020JPG-1.jpg

The seams were also sealed to prevent corrosion.

After the primer was sanded to 600 grit, Jeff sprays a satin black urethane on the firewall.

Once the paint dried, the satin finish was revealed.

Once the firewall was cured, the mechanic shop took over with the final install of all the goodies.

https://static1.pt-content.com/images/pt/2018/03/19692BCamaro2BLA_201803140001JPG-1.jpg

The Detroit Speed subframe and suspension was cleaned up amd the new firewall protected as the LT4 was set in place.

The team begins to install the various systems on the car and LT4.

Engine wiring is routed low through the bulkhead plate made in our metal shop.

The Ultimate Headers are exhaust artwork, with cast stainless flanges and stainless tubes. The ARP hardware squeezes MLS gaskets, and the headers utilize 1 ⅞” stainless tubes. These are Jet-Hot coated satin black.

https://static1.pt-content.com/images/pt/2018/04/19692BCamaro2BLA_201803140029JPG-1.jpg

Superchargers create a lot of heat, so the cooling system needs to be effective. The LT4 will be keeping its cool thanks to a C&R Racing radiator and supercharger heat exchanger. These are bred from C&R’s F1 racing program and offer many innovations for performance and strength.

The heat exchanger is designed for the Camaro’s grille opening size.

https://static1.pt-content.com/images/pt/2018/04/IMG_9117JPG-1.jpg

Pins on the bottom of the heat exchanger locate it in the mount, which uses rubber bushings to protect against vibration harm.

https://static1.pt-content.com/images/pt/2018/04/IMG_9112JPG-1.jpg

Mounting “shelf” with rubber bushings.

A rubber padded top mount slips between the stock Camaro support and vertical bracing.

https://static1.pt-content.com/images/pt/2018/04/IMG_9123JPG-1.jpg

Note the 4 mounting tabs and screws, those are for mounting a Vintage Air condenser core to the front of the heat exchanger. These are provided by C&R.

[oestek]

On the back side, the radiator is mounted to the core support.

https://static1.pt-content.com/images/pt/2018/04/IMG_9213JPG-1.jpg

A high fin and tube per inch count increases surface area for better cooling, and the tubes are actually extruded for strength. These are shots of a cutaway:

https://static1.pt-content.com/images/pt/2018/04/19692BCamaro2BLA_201804170010JPG-1.jpg

C&R builds these tube cores to withstand pressure of 100 psi in F1 racing, a pressure they won’t ever see in a street car like this, but they withstand “ballooning” and potential cracking and bursting like rolled tubes.

https://static1.pt-content.com/images/pt/2018/04/19692BCamaro2BLA_201804170007JPG-1.jpg

They’ve also added reinforcements to the structure to keep the tanks and cores from separating and leaking.

https://static1.pt-content.com/images/pt/2018/04/19692BCamaro2BLA_201804170009JPG-1.jpg

The driver side incorporates an engine oil cooler, and the twin Spal fans are visible here.

That's awesome that you were able to retain the stock hood latch! Seems like many people ditch them in order to get the space needed. Nicely done!

[oestek]

Thanks! The real challenge is fitting the RS headlights with the oil reservoir... more to come on that!

Things are coming together on the LT4 swap.

https://static1.pt-content.com/images/pt/2018/06/IMG_9351JPG-1.jpg

Supercharger coolant pump is mounted low on the subframe.

I enjoyed the look at the intake side of the engine. Coming along very nicely. :)

[vstol]

looks great

[minendrews68]

Man, seeing these pictures makes me want to sell my house and have Kevin do my Camaro!! I don't think my wife and kids would totally agree with me on this though.

[oestek]

Great thought... maybe you can have your wife and kids pick the colors! Seriously, thanks for the kind words, and I hope you are able to involve your family in your projects somehow. It makes for great memories and quality time together. Unless you sell the house, that is.

[oestek]

At this point, the decision was made to install the later version of the LT4 supercharger hat, which will accommodate water / methanol injection jets from Nitrous Express.

Water / Methanol injection is a great tool to reduce the intake charge temperature, allow for more aggressive ignition timing, and therefore increase the power output of the engine.

The system uses basically the same solenoid system as a nitrous oxide kit, but this time, it’s spraying a water / methanol blend under much lower pressure. A reservoir tank and pump are needed, as well as some form of controller to make it work.

Here, the jets are plumbed into the new hat and the solenoids are mounted. Nitrous Express provides this service, which came out great.

Alcohol pump:

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805150017JPG-1.jpg


The new hat didn’t match our desired color scheme, so it was cleaned, scuffed, and masked for some new color.

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805150032JPG-1.jpg

First color is a charcoal gray found in various accents on the car, like the window trim and door handles.

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805150043JPG-1.jpg

Then the fins were masked and the second color was applied, a bright and vivid red.

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805150047JPG-1.jpg

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805150056JPG-1.jpg

After unmasking, the fins were stripped and the ribs were returned to a natural aluminum finish.

https://static1.pt-content.com/images/pt/2018/07/1969_Camaro_LA_201805170062JPG-1.jpg

The end result looks factory clean and custom tailored to the car. We also tuned up the LT4 badging and gray on the coolant hoses.

Looking good!

The liquid side of the alcohol injection system required a pump and a reservoir, so we built a tank to fit in the driver side rear quarter panel out of stainless.

The tank and pump fit neatly in the trunk.

Next, the team wired up the T56 Magnum transmission using a Bowler All In One harness. This is a handy piece that incorporates all the connections required on a T56 for safe operation into one harness.

https://static1.pt-content.com/images/pt/2018/09/1969_Camaro_LA_201806050210JPG-1.jpg

From Bowler:

“The All-in-One harness solution for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up you will be able to connect via Bluetooth to your Apple or Android smartphone using our free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The All-in-One harness eliminates the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. This All-in-One harness solution is the perfect finishing touch for any Tremec T-56 Magnum conversion, and the only harness you will ever need.”

Unit mounted:

https://static1.pt-content.com/images/pt/2018/09/1969_Camaro_LA_201806050217JPG-1.jpg

And the Dakota Digital OBDII interface to send the signals from the ECM to the dash.

https://static1.pt-content.com/images/pt/2018/09/1969_Camaro_LA_201806050220JPG-1.jpg

These devices simplify the communication betweed various digital and analoge systems making it far simpler to perform these kinds of swaps.

Soon, the intake tube was made and the LT4 was ready to fire!

The LT4 was finally ready to fire, and the crew double checked all the connections, hoses, fittings, and added some fuel. The calibration is from the GM Performance ECM with some adjustments made to accomodate the Drive Junky pulleys, exhaust, and custom air intake. We use HP Tuners software and worked with Mike Norris on the calibration to get the car in a driving state.

https://static1.pt-content.com/images/pt/2018/09/1969_Camaro_LA_201809180005JPG-1.jpg

Initial drives we casual, as we datalogged the ECM and would beam it over to Norris for analysis. We’ve tuned many an LS, but this was LT4 #1, and we trust Mike to be a great resource on these kinds of projects.

https://static1.pt-content.com/images/pt/2018/09/1969_Camaro_LA_201807030229-1.jpg

Soon we were ready to strap it down on the dyno and put some power to it and perform more datalogging and refinements.

Driving the car is a blast… when the power comes on, you’d better be ready! It shreds tires at will. Two V8 Team members Trevor and Tyler took the car on a 600 mile shakedown run to the Holley LS Fest in Bowling Green, KY, with no major issues, save for a power steering leak at the rack. Overall, it was a great ride for them. Our freinds at Forgeline were kind enough to host the car for the weekend.

However, we’re not at the finish line yet. It turns out that the car has an issue with the throttle during upshifts where the RPM climbs a bit after the throttle has been closed. It seems this is a “thing” with LT4 swaps, and we’re working with GM and a few others to land on a solution… more on that shortly!

First off I have to say this is a great build. I think Kevin has a eye for detailed work. On the other hand, I had PM'd Kevin about the rough cost of doing this type of upgrade. He replied that it would be better if he called and we talked about it over the phone. I was surprised when we finally talking. I figured as busy as he is it would probably slip his mind. He would text me and tell me when he was going to call and if at that time he couldn't make it he would text again and set up another time. I told him that it was ok, don't worry about it because I couldn't afford to do it, that I was just curious. He told me that it was ok and that he didn't mind going over some of the things he did and cost. We finally got together on the phone and I apologized for taking up his time because this was just a curiosity thing. We talked for about an hour and he told me about what each phase would cost. He never came out and told me what the client had to pay which I thought was admirable. Maybe the client didn't want everyone knowing. What I'm getting at is that Kevin took the time out of his schedule to call, knowing that I was probably not going to have my car done any time soon.

Great job Kevin! If I ever get the money together he would be doing my work. Just a little "Atta boy" sent your way Kevin.

We discuss our fix for the LT4's RPM issue in the latest episode of V8 Radio. You can jump to the 43 minute mark to get right to it (but you really want to listen to the whole show, right?)

** We don't reveal the fix, but we do discuss how we approach these going forward. It will make sense if you listen.
