Camshaft question

Hysteric said
So if we close the intake sooner we build more cylinder pressure right?

Now go back and look at that so called cam test and look at where the 101 vs 113 camshafts closed the intake and look at the cylinder pressure differences as a result.

Is it really about LSA or is it really where we close the intake and how much cylinder pressure we build.

Uhmmm, it's about both......they have different functions, and can be equally important depending on the application.
Pro Stock heads obviously aren't following the same pattern as a pocket-ported J head.
I stated (accurately), that the cam listed would suck the wind out of that stroker, and it will.
