Cam

I just built a motor for a 1991 camaro rs, a 350 bored .040 over and i had it all together and decided to put some 2.02 heads on it and i'm keeping the stock cam in it because of time...my friend things that is stupid, and I agree putting a 270 cam would be better, however will I notice a huge difference and will I regret not putting one in....???

im gonna need more information on this before i can tell you one way or the other. for instance....

stock exhaust or headers?
what kind of intake are you running?
computer controlled or stripped down to a carb?

2.02 is a valve size, not a type of cylender head, what kind of heads are they?
What are your rear gears?
What stall converter are you running? or is it manual?

I would also suggest calling comp cams cam help hotline, its a 1-800 number and they will be able to help you out the best. If everything is stock about the car, except the overbore and larger valves, i would say the stock cam is a bette choice, or at least something smaller than a 270 cam say 252 instead.
