Missed on this combo?

Well my opinion is a lot of builders definitely inflate numbers. Sometimes I wonder if the dyno sheet is even from THAT particular motor.

I love seeing those 600 HP builds with an Airgap and .520 lift cam. I hate to admit it but some of his more recent builds looked a little suspicious to me. Not hatin', just sayin'.

I've said it before but you spend a few hours dyno time and you get a real healthy respect for how hard it is to make power.
