I'm putting back together the 302 for the 69, any suggestons for what cam and heads to use?

Those look good I wonder which would be a good application for me 180cc or the 200cc runners, or would going up to 215cc with the 2.05int. work on a mostly street application, but it needs to have the ability to blow the doors off anyone.

 
those 302s rev quick. so i would say good air flow so it dont choke it self. call and ask them what thay recomend.
 
id say dont touch the 302. leave the thing stock and pull it out. build up a 350 and put that in. the 302's are rarer by the day and worth a pretty penny. if you have the original parts it would be worth alot of money. just me though. 302's are killer motors in stock shape but as much as they're worth i wouldnt touch it.
 
Thats whats in there now, is't a 350 with all the goodies putting out around 600 hp. The problem is it's not really drivable for street use. And the 302 was fun with the four speed so the block wasn't number's matching so why not.​
 
is the motor itself numbers matching? doesnt matter if it is to the car but if the motor is original id keep it original cause its worth alot of money to someone. at the very least keep all the parts from it so you could resell it at a later date like it was originaly.
 
also a decent built 302 aint great for street uses either. the things rev so much and dont make a ton of torque (cause there short stroke motors) the only real way to run em is wide open:D

A good friend has a 302 in a 69 Camaro and it does fine on the streets. It's not a majorly heavy car, and he's not pulling anything with it, so it's not like a torque monster is needed. Sure, it has some deeper gears then latter Camaros, but 4.10's were fairly comman back in the muscle car days.
 
Rite now I've got a chassisworks fab9 rear end w/4:11 and turbo 400 and if I swap in a 5 or 6 speed it should be a blast if I build the motor rite :eek1:
 
I'd run around a 190-200cc head setup with a 5 or 6 speed myself. Revving high and flying fast are amazing things ;)
