Read the thread I just posted. There's a reason you have to run more comp with a bigger cam. Think about what you trap in the cylinder before commencing the burn. AFR has very little to do with it.
In all respect, I don't need to read it to understand. Bigger cams want more compression, I've known that for many years.
What do you think would be the winner in a 1/4 mile race if both were in a Duster with 3.23's and a stock 904 (just to favor low end torque).
A 360 with a 318 2bbl on top of a 318 2bbl intake, a set of stock 318 "302" heads, 318 2bbl cam, flat top standard bore pistons, 318 exhaust manifolds with single exhaust.
A 360 with a 750 holley, Eddy RPM intake, Lunati 703 cam, 360 heads that are fully ported, headers and dual exhaust BUT keeping the stock dished pistons and using a .050 thick head gasket.
One has a lot of compression but no flow, one has a lot of flow but no compression. So which one crosses the line first?
