I have a Corvette with a 454 that is 270 HP stock ,I believe, and would like to get some more out of it without pulling the motor.It has a brand new cam in it so I hate to tear into it right now.The guy I bought it from doesn't know what cam is in it either but it is really smooth so I'm assuming it is pretty tame.Maybe intake and carb???any ideas would be much appreciated. Mike
