Ok guys, put your thinking caps on. I have a problem, and as the best chevette group in the world, together we can figure it out. My problem is, I'm not turning the rpm's I think I should be turning. I run on a 4/10 mile high banked paved oval, I have to run in 3rd gear, I have tried running in 2nd, but I cant. The engine sounds like it is going to explode. Now, with running in 3rd, I'm only turning 2500 rpm's, Which I feel isnt enough, the cam does come into range until 4400. We have tried changing jets in the carb. ( holley 350cfm) Im running a 370 rear gear, I race on 23.0/7.0/13 hoosier sportsman racing slicks. the motor is bored .50 over, head has been shaved around .100th, the cam is a the lazer 300, the car just doesnt have it, any suggestions? Thanks in advance. Randall

Does anybody know what RPM I should be turning, with a 370 gear on a 4/10 mile track. At 2500 rpm's going into a turn, I dont lift the throttle, WFO, kinda fun, but I still think I should be faster, and turn more R's.

Try a 336? Run it in 2nd gear? What kinda rpm's would it turn? I would think it would be a little on the tight side of around 8 grand?
