Yeah, our 85 Camaro was a pretty rough and ready street machine that we used to take to the local 1/8th mile every so often.
Goodwrench crate 4 bolt 350, GMPP Fast Burn heads, Comp Cams Magnum 270H, Crane roller rockers, Edelbrock Performer RPM intake, Holley 3310 with the choke tower milled off, Hooker Competition headers with a true dual exhaust (this is DIFFICULT on a third gen! But we did it!) leading into Dynomax glass packs (because that's all we could find that would fit), TH350 trans with a B&M Shift improver kit.
We started with the T5 that came in the car, but almost instantly broke the clutch. Put in a Zoom, broke that one too. Pulled the T-5 for a TH700R4, broke the sprag. Finally, we said screw it and went with the TH350. Not sure if you're familiar with 3rd gens, but there's a torque arm that runs from the transmission to the rear end. Only T-5's and TH700R4's have the appropriate tail shaft for that arm, so we had to fabricobble one to make the TH350 work. When we did that, what was already a sketchy car around corners before became a squirrely nightmare! But that's okay, we weren't road racing anyway, just stoplight drags and the occasional Friday Night grudges at the local track.
Biggest problem we had with the car was getting it to hook. We had rock hard P295/50R15 BFG Radial T/A's on the back, and they just plain stank at the track. Horrible. But even then, we could still run a 8.3 at 84 mph. That's not bad at all for a pure street car with a huge stereo in it, especially 25 years ago when we had it!
