well the flow bench numbers look really good............ stock is around 213 cfm on the intake side @ 28", after extrude hone 241 cfm @ 28" on the intake and 196cfm on the exhaust side.

I ported the **** out of the cast turbo manifold and we've got a full 3" exhaust now, that w/ the custom intake manifold, big cams, and .82 a/r exhaust housing........... this thing should ****ing rip.......
