look at that, you learn something every day, i guess that must a be a older grind, because none of my catalogs show that 7, internet shows its for stroker motors..hmmm, Well on the contrary, bigger is better when you do it correctly, When you have enough head,compression,gear and bike weight figured in, all that has to support a camshaft, One things ive noticed with harley guys, they like to throw gigantic duration, high overlap cams in with next to no compression, thats a bad thing, ive personally done it with a small block chevy in a 4x4, and it was turd,

Yea, that why I've had so many questions... My bike runs great now. But, if I could get a larger cam that matches the CR and heads better, I just may do it..

Yea, i hear ya, I just looked at your other thread, The limiting factor on your build is the compression, 9.5 to 1 is a good middle of the road compression, but if you going to do a longer duration camshaft, youll need to bump that up with another piston or having the heads decked, or both...lol.

What are you noticing on detonation with the high comp? Is it bad or can it be easily dealt with, with pump fuel?
