After I finished the wiring and aligned the body panels, I did a little body work and then took everything apart to paint the firewall. It was good seeing the car again in one shade again even if its primer.

I was going back and forth on building an engine or using the stock ls2 block that I had. I really wanted to build a big bore engine but I didn't want to spend too much on the engine while the car wasn't finished. I ended up getting a new ls3 block with mahle 2cc dome pistons, with a custom cam spec by Pat G. With my l92 heads shaved .010, the compression ratio should be around 11.2

How did you make that access panel for the fuel pump? Or did you buy it already assembled?

I got my engine back from the builder primed and ready to go. I decided to ditch the gto accessories and use the new Holley midmount accessories. For now I'll be using a ls7 clutch with my gto t56

The Holley midmount kit is so badass. I wish that was available when I did my GTO swap.

Awesome build too. Keep up the good work!

Finally, the engine is installed and ready to go. Fired right up and everything seems good to go. Now I have to get tags and insurance to get the car roadworthy so that I can break the engine in.

I haven't updated this thread in awhile, but last year my engine dropped a valve and had to be replaced. My engine wasn't damaged too bad so I decided to save it for something else and build something a little better. Here are the specs on my new engine.
ERL sleeved ls2 block 4.155 bore
Compstar 4.00 crank and rods
Wiesco -8cc flat tops
Advanced Induction 280cc ported ls3 heads
Comp Cam bsr shaft rockers
pat g custom cam 241/250 .629”/.615” 114 LSA +3
Holley 302-3 pan
Monster lt1 twin disc clutch

I reused my accessory drive from my last engine, and I'm still undecided on the intake and headers.

I've have also been busy getting the car ready for paint, it's actually in the shop now. I've decided to paint it black with Matt black stripes.

I have also shaved the rear marking light and tucked and sectioned the rear bumper.

I blew my wheel budget so I settled on some cheap wheels for now. They are riddler 650s on Nitto nt05 tires. I had to use a small spacer so that they wouldn't hit my brake calipers.

Specs on those wheels? Iv been looking at the riddlers for a little but now. Just need to decide on 17s or 18s and how wide. Not real sure how wide I can actually go in the front or back on my 68.

Sweet ride btw

The wheels are 20x8.5 for the front, and 20x10 for the rear. 0mm offset on both sets.

While waiting for my engine to be built, I worked on the body some more. I repainted the firewall and realigned my doors and fenders and blocked the car down again.

That's on stock axle width and no tubs? I didnt realize there is that much room.

The front tubs are stock while the back is minitubbed. Although I've seen Chevelles running these size tires without being minitubbed.

Good to know. I still plan on test fitting but knowing someone with roughly the same setup helps alot. I was worried the 18s wouldnt look right but those 20s like pretty nice. Thanks for the info and that's one sexy ride for sure.

A little sneak peak from the paint shop, the car is still in the process of being cut and buffed. I decided to my stripes a little different than the normal ss stripes. It feels good to have paint on it after 4 years.

I found a good deal on a set of autometer fuel pressure and aem wideband gauges. I bought an autometer gauge pod to mount them. Even though the gauges have a white face, they look good next to gray hdx gauges.
