Here's my combo, 383 forged internals, 10.7/1 compression, summit aluminum heads(supposedly based on Brodix heads) specs on those is 64cc, 200cc intake, 72cc exhaust,2.02/1.6 valves, 750 holley carb, air gap intake, 2500 stall, 3.73 gears. The cam I have now is 236/242 .52/.54 110 lsa, its a retro roller cam. Comp recommended me to go to a 248/254 .562/.58 110 lsa, but I thought it was a bit much for a car that sees more street than track. I thought this cam may be better, 242/248 .54/.58 110 lsa. What do you guys think I should run. I want it be somewhat streetable like the cam I have now is, but I could use a little more power.

 

Before buying parts, lets see if what you have is giving what it should. Go get the car on a chassis dyno, then post your results for us to evaluate.
