What kind of cam profiles and gear ratios are some of you SB Chevy guys using?
Obviously, if the motor has a lot of camshaft, it will want some gear ratio to make it work. But I'm not sold on the idea of a lot of camshaft being necessary for a vehicle that is so light. I'm definitely not sold on the idea of increasing static compression ratio, to make up for the longer cam profiles, either. The attendant increases in fuel requirements is not a strong selling point for me.
I'm thinking that something around 230 @ .050 is likely more than enough camshaft to get the job done. Even at that, I suspect that loosening up the converter at least 500-750 RPM might be wise, taking into account the curb weight of the car.
Let me hear your thoughts and ideas.
