Try telling that to my 360. It goes 7200 for 11 years and at up to 11.2 Scr on nothing but 87E10.
My KB107s are .005 up out of the hole, and although the current gaskets are .039s, It has run with the .029s as well.It has never run less than 32* power-timing, and is happy at up to 36*. I have run 3 different cams in it with the same results; no detonation.
In any case my comparo had nothing to do with horsepower whatsoever.
