I don't know what intakes will fit under the hood of an 82. It has a buldge that hangs down into the engine bay for the cold air induction. I want to keep the stock hood.
The engine is a 50,000 something motor. The engine with heads will be left as she sits, I am just sticking a cam in and putting an intake on it. I have no plans on touching the converter, or rear end.
I was thinking a Performer intake, with a 600 Holley, and a dropped base air cleaner. I was also thinking a Performer cam to go with it.
After looking at the cam specs, it looks kinda tame (.420"/.442" and 204/214 deg at .050) I had this combo in an old Regal years ago and it felt strong down low. This is, and will be my daily driver so it can't be wild, or have the power too high in the RPM range, just some grunt in the city.
I think you're on target. Keep the torque down low and it's much more fun to drive. CHP built a 406 with torque in mind. They used dished pistons to keep the CR at 9.5:1 with 64cc Vortec heads that have 170cc runners, and a Vortec Air Gap manifold. The cam was a single pattern Lunati with 230 duration at .050 and .480 lift. Carb was a 750 Holley. 428hp and 525 lb.ft. torque!! Best part is that peak torque was at 3500 RPM's. Perfect! (peak HP was at 5000 rpm)
I agree with Chris69 and EDDIEJ82:
.460" lift, no-more than 220* duration at .050" lift will make good bottom-end 'grunt', which you'll need, if not changing-out those 2.87 gears.
You might find a 'cheapie' L-82 intake laying around somewhere from a '79-earlier Vette;
it's nothing 'great', but it is aluminum, will mount-up a Q-Jet or spread-bore Holley, and probably will fit under you hood.
I understand you'll need 'something' to activate torque-converter lock-up, and with-out a good 'beefing-up', the 700R4 will give-up soon, too.
Ya, I know about the tranny issues. I went with a Bow Tie Overdrives kit on my 70 Camaro for the TV cable, and another kit for the lock up converter.
For this project I went back to a July 2000 issure if Chevy High Performance. They had an article showing how to wire up the lock up converter, they used 2 GM parts, for a total of under $25. Lock up takes care of itself, no switches to flip or anything. It's a pretty slick setup
I went with the Edelbrock Performer Kit which consisted of 600cfm carb, 2102 cam, and performer manifold. I am extremely happy with performance as the old components had 70K + miles on them. It Feels like a whole new car!

this combo would be a blast to drive, about what im going to do to my 383
