Just a bit more info on the build: We did bowl pocket porting on the cylinder heads only. NO port matching on intake or heads. Camshaft is installed on 104.5 in take center line and 112 lobe separation . 10.0:1 compression Holley 850 double pumper not modified. USing stock Mercury Thunderbolt ignition. I see alot of good guesses out there! .... By the way we are step testing this engines to 6000 RPM
