MTBSully's First Restomod: 1969 Camaro LS Build

[Vimes]

Seeing as installing minitubs includes cutting and welding the body shell anyway, how about clearancing for up to a 4 inch diameter exhaust while you're in there? I know hanging the exhaust under the axle is done, but I've never liked the idea of it particularly on a lowered vehicle. 3 inch pipe under the axle, plus a bit of clearance past full extension since you don't want jacking it up (or getting some air) to knock it off, might mean just a couple of inches between the exhaust and the road.

Looking great! I like the position of the x pipe. I personally wouldn't go under the axle either. I had plenty of room to go up and over the axles with my 3" exhaust pipes. The spot that I had the most trouble with was fitting the 3" exhaust pipe between the quarter panel and leaf spring. I can't remember if you have a 4 link or not, but if so, you should have tons of clearance.

[MTBSully]

Done. Just need to spend the hours to finish weld it now lol. Went under the axle. Just seemed like it would be tight with a mini tub and some wide tires, but i can easily change it to go over the axle if it turns out there is room. Basically just move the 2 45 bends back 4-6".





Ground clearance is basically un-affected. The exhaust is parallel with the pumpkin and the frame, as well as the subframe connecters that I really should order and install lol. Gobs of ground clearance compared to my c6 corvette. I think the pipes look badass from the back too. Reminds me of my 03-04 cobra IRS exhaust days. Definitely going to mirror polish that section out once its finish welded so it looks nice from the rear.

Can't wait to hear how it sounds.

[MTBSully]

Exhaust is done. Havent driven it yet but it sounds awesome idling in my driveway lol.






With some actual exhaust behind the header collector, I was actually able to turn on closed loop, as well as learning, so the holley is making adjustments to the tune. Base fuel pressure is set at 48PSI, hooked up a vacuum line to the regulator as well.

Pulled the saran wrap off the front end for the first time in 10 months. Feels good to see this thing outside and all together.



Sound clips coming soon!

Sound clips coming soon! Now need to diagnose why the car won't shut off with the ingition and continues to run even with the battery disconnected lol. My guess is somehow the alternator is backfeeding the ECU. Not sure how that happened all of a sudden since I didn't change any wiring with the ECU, but I think a diode in the alternator excite wire should take care of it.

[MTBSully]

Exhaust video is up!



Also figured out why the car wouldnt shut off with the ingition. Somehow I had wired my reverse lockout solenoid to one of the holley inputs instead of the outputs. Still not sure how, but someohow this circuit must have been feeding the ECU since the ECU would not shut off with the key. I corrected this wiring and all is well. Too bad it took like 4 hours on sunday, but it should be good now. Up next is a bezel for the holley pro dash!

Been a minute since an update. Been busy with a z06 project I picked up.

had the car out a couple times. Even took it out in rushhour traffic on Friday for its first real cruise! No issues to speak of, tune still needs a little work but it is getting better as the holley learns. Felt great to drive it. Took it to a buddies shop to finally get the AC evacuated so i can hook up the mini compressor mounted down low.


Even got the christmas tree with it!


Need to make some AC lines using my new AC crimper tool. Should have the fitting in by the end of the week. Then need to get to work on my Holley dash bezel!

Now that's a pic u don't see everyday.

That Tree shot is amazing!!

[MTBSully]

Once again been a while since we've had an updated. Vacation, the flu, bachelor parties and finishing my z06 project have taken a lot of my time over the start of 2023. But i'm itching to get to work on the 1969 again so its ready for spring!

Finally made the AC hoses for my low mount sanden compressor using my AC hose crimp tool. No just need to charge the system come spring time and hopefully it works!

Uncovered to get some work done. Just picked up this onyx indoor cover and I love it so far.


AC line made


Radiator closeout panel in flat black. Really cleans up under here. Now just need to adjust it so the hood will close properly. It closes but takes a lot of effort.


And finally, time to tackle the project i've been putting off for over a year. Cramming the 12.3" holley dash into the stock cluster. Gonna try anyways lol. Time to get cutting with the dremel!

Looks great man! Was wondering what happened to this build. Be interesting to see how you cram that dash in there.

[-KILO-]

what 4" tips are those and where did you get them from?
they look perfect on the car

I looked thru the thread and saw when you purchased them but didnt give any details.

thanks!

Thanks! Got them on ebay. Just search the size you need and other key words you want like "stainless" and "double walled" etc

Been a minute. Life keeps getting in the way lol. No plans other than work and car stuff for the next few weeks so hoping to knock some stuff out on this car!

Been chipping away at this bezel. Hour here, 30 minutes there. Progress was slow because I havent had much time, and also waiting for my acetone/abs "slurry" to dry while adding pieces. The full process will be explained in my youtube video once its done.

After much cutting with the dremel and death wheel


Template made out of cardboard


Transfered to ABS


More cutting, turns out I only needed the sides of that filler piece lol. test fit of the dash


More templates, more filler pieces


Reinforcing/bracing/ more gluing


Heres where we are at. All filler pieces made. Everything is filled in, now begins the hours of sanding/"bodywork" to make everything smooth and look like it was one piece of plastic


Hoping to finish sanding and maybe get a coat of satin black on this thing in the next day or so and then get it in the car!

[ryeguy2006a]

That's going to look great with the digital dash in there. I'm hoping to do something similar with the dash on my 55 down the road.

[andrewb70]

Great progress. If you need any assistance with the Holley EFI tuning, keep me in mind.

Video is up!



Finally finished the bezel. Many hours of sanding, shaping, filling, sanding, more filling, more sanding and painting later and its done! Looks almost OEM!

[MTBSully]

Anyone have a good spurce for 2nd gen "bullet" mirrors? Thinking of picking up a set for the car and painting them. Do they bolt right on?

[andrewb70]

Great job with the Holley pro-dash installation!

Andrew

[ryeguy2006a]

Wow, that dash looks great!! I'm curious though why the dash is set up for boost?? Is there something you aren't telling us?
