69 Camaro LS2/4L70E install

[rocketrod]

I am finishing up a frame off restoration with an LS2/4L70E install. Everything on the car has been replaced or refurbished except. This thread will provide a detailed account of my LS install complete with parts list (part numbers included) and pics. The goal for this swap is to get the stock motor/trans installed and running ASAP. I would like to do a cam/head swap now, but performance mods will come later, because as we all know these cars are never done and I would like to drive it for a while.

My decision for the LS conversion was bittersweet. On my previous motor, 355 SBC, I installed a very mild cam, was able to turn the motor over easily by hand, only later to learn how important it is to actually check piston to valve clearance. Once I determined the motor was toast, cracked block, trashed head and piston I started researching my options on pro-touring and ls1tech. I quickly came to the conclusion I wanted to do an LS conversion, even though I have no experience working on LS motors.

As I started looking for a motor, I fortunate enough to find daytonayellaz (Travis), who spent hours on the phone answering my LS conversion questions and providing invaluable insight/recommendations. I also had many pm's with Magntik (Jeremy), who bought the same setup from Travis, who answered additional questions and in the end I purchased a LS2/4L70E out of a 2008 TBSS from Travis.

As for the engine, the longblock had been replaced under factory warranty and has less than 900 miles!! The rest of the of engine components and trans have around 18K miles. Needless to say the motor extremely clean! I would highly recommend contacting Travis if your looking for an LS engine! He is a great guy, who I would now call a friend, and continues to answer question I have and has even called me a few times to see how things are going.

I don't recall you saying it had 900 miles on it! And you painted it? There can't be enough miles on it for the inside to get dirty, let alone the outside!! LOL

Just kidding, glad to be able to answer some questions rather than just asking them.
Good luck and let me know if I can be of any more help.

I agree! I already have good feeling about this swap. The motors are relatively easy to work on and I really like the reusable intake, water pump and valver cover gaskets.

Nice RocketRod! Looking forward to seeing your progress! Engine looks nice! Car looks nice too! Need more pics and info on it.

Here are a few pics of the car when it was together and during the frameoff








I purchased the car in August 2004 as a driver. The previous owner had done a frame off installing new GM quarters and applied a very nice paint job. The rest of the car was functional, but woefully out of date with drum brakes, turbo 350, stock suspension and weld superlites. Over the past seven years I have made the following improvements.

• Removed subframe and had frame, inner fender, rad support, headlight brackets, etc powdercoated.
• Smoothed firewall using Mikes Custom Cars firewall panel and replaced dash
• Sandblasted undercarriage and applied por-15
• Installed 12 bolt posi trac rearend with 3.73
• Installed Baer disc brakes, 13" up front a 12" out back with new stainless brake lines
• 17" Budniks Cobalts with 275s in the rear and 235 up front
• Installed Hydratech hydraboost
• Hotchkis front sway bar with Bilstien shocks on all four corners with Global West UCAs
• Installed Global West subframe connectors and solid body bushings
• Installed Vintage Air Gen IV A/C
• Installed AAW Classic Update wiring harness
• Added Marquez Design tail lights, running lights, side marker bezels,
• DSE Billet hood hinges, hood striker, wiper motor, headlights and battery mount
• DSE dash insert with Autometer Ultra Lite electrical gauges
• Lined interior with Damplier Pro, Luxury liner Pro and Firewall
• New front and rear bumpers

Great start. The paint looks nice and it is refreshing to see a vinyl top car from time to time. Yours looks right with the top.

I got some time to work on the car this weekend and decided to clean and paint the motor, trans and accessories. After taking tons of pics I removed the harness, accessories, intake etc.

To clean the motor I used a degreaser called Super Clean, then wiped everything down with lacquer thinner. I taped everything off, applied two light coats of SEM Self etching Primer (rattle can), then topcoated with 2-3 coats Shop-Line series single stage paint. The color was poly silver with a light metallic. I am pretty pleased with the results! Total cost
of the degreaser, primer, reducer, hardener and 1 qt of paint was about $80.

I still need to install the Mast Motorpsports oil pan, get new motor mounts and transmission dipstick before I can install the engine.

Pics of motor with self etching primer applied at about 1am.

The paint looks great. How well do you think it will hold up?

Nice job it came out great.

Now that I have the engine painted and all these parts it's time to get to work!

First order of busines was to install S&P adapter plates and stock motor mounts. In order to use the stock mounts you need to slowly grind away the hump on the back of the mount so they sit fluch on the adapter plate.


Next I removed the enormous TBSS oil pan and oil pump pickup tube.


The TBSS oil dipstick tub was located in the side of the oilpan. I needed to install an LS2 dipstick tube in the block so I needed to remove the small plug from the block. I just used a small punch & hammer and from the bottom of the block tapped it out.


Next I installed the Mast Motorsports oil pan and oil pump pickup tube per the instructions. The Mast pan is a pretty nice piece. Here is a pic of the motor already to install.


I still need to do some wiring work and general cleanup, but I wanted to test fit the engine now so I could check trans tunnel clearance, header fitment, ensure motor mounts work and there are no other surprises later. So with the help of my father we decided to put her in!!!


As luck would have it I had a couple minor issues getting the motor in. For starters, the motor mounts would not line up with the engine stands. I could get on bolt in, but the other was about 1/2" off. I ended up removing the mount and elongate all the holes on each mount. It took a couple times, but finally I got it in. Still a long ways to go, but I like what I am seeing.


Next came the Stainless Works headers. These are really nice pieces and I would highly recommend them!! Of course the motor had to come out because they would not go in from under the car. Once they were the the #1 header tube ever so slightly touch the bolt on my gearbox as shown in the pic below. I will mark the header and lightly dimple the tube and grind away a little of the bolt head.


Next is installing the new LS2 intake. Actually this was day prior to installing the engine. Anyways I heard there may be clearance issues using a car intake with the TBSS TB and there is but on the 2008 models the it can be done if you grind away a small protion of the water pump housing.


The next pic shows the TB installed and a very small gap and at the moment I am feeling victorious, but its a short lived victory. I want to use LS2 Corvette engine covers and contact the TB and would require more triming that I car for....so I will be installing a Corvette TB to mitigate this issue.


Here are a few more shots with everything mocked up. I don't know if I am going to stick with the Kwik brackets. It's a nice piece, but I am thinking about going with a Corvette setup, but we will see. If I keep it I will probably have to install a 2010 Camaro water pump as it may be difficult to find an upper radiator hose that makes and immediate 90 degree bend off the TBSS water pump.

The conversion is actually coming together a lot faster than I anticipated and not nearly as difficult as some make it sound. I am very pleased so far...here are a few pics.

That sure looks pretty in there. The engine bay looks great, nice progress.

[BulldawgMusclecars]

Looks really good!

[Speedy911]

Looks great, the swap is coming along nicely!

[rocketrod]

Well due to work I haven't gotten anything done to the car in the last two weeks.....anyways I did find a few moments to start checking clearances and laying out the wiring and other things that need to be done. I should also be receiving my gas tank this week and the wiring harness soon!!

I did find a header clearance issue. As the pic shows the #2 header tube has about 1/8" clearance on AN connector on the gearbox. I can dimple the area a little, but personally I don't think it will be enough. I may put a heat shield over it and run a power steering cooler. Anyone have any thoughts on this?

[rocketrod]

Well I haven't gotten to work the car in almost a month, ggrrhhh, but one of my major parts arrived today and I thought I would share.

mmmmhhh I wonder what it could be...


This is one part of my build that I splurged on a vaporworx tank! It's a shame this will be tucked away underneath the car as the craftmanship is top notch!!! Now if I just get some time to work on the car.

Project is looking good Rod!

Project is looking good Rod!

Thanks! Your car is one that got me inspired to do this conversion....and the fact that my old motor ate an intake valve and destoyed itself...

Oh man! You're gonna love that tank and fuel system! It really is a nice piece of workmanship, both the tank, and the pump/controller system. Carl did a fantastic job! You will hate the VDO sending unit though. At least I do. Mine doesn't work worth a diggity dang.

Thanks...care to elaborate on the VDO sending unit...

[Bmf5150]

Yeah I got the ricks gas tank and my sending unit sucks,never tells u proper fuel amount!I called them about it and suggested I call Isspro
800-888-8065 and they could make a Custom made sending unit!!also my stainless steel works headers are tight in the same place as yours!
