I've got me a intake minifold ported and polished and plan on bolting it on. Does anyone have any idea how much hp I will be adding? Will I feel it at the rear wheels?

I believe anywhere from 25 to 40..I just did the heads on mine also and used an old gasket to see how much I could take off. I also had them CCD with a 3> valve job and am putting my motor in this week... can't wait to see what it does! Good luck with it!

I'm porting and polishing my head too and had it surfaced at or shop 50 thousands. I'm cc ing my head too.
