I haven't changed the shortblock since the beginning so it is still 10.5 compression with the SCAT crank and Diamond pistons. It currently has the Comp cam in it which is 264/268 duration. What I've been testing lately is the rocker arms and then I've tried some different carb spacers and stuff like that. High level summary is that it makes 700 hp with a Trick Flow intake and a QF carb. With the Wilson intake and a Dominator it makes about 720 hp.
