if its a stroker its gonna make more power, but not rev as high. you need 795 series pistons and a spacer plate or the head cut. I would call a builder like Herr Jugs racing or F.A.S.T and talk to them about it. It's probably a 4 mill crank with long rods. you need to have the cylinders ported, get the head cut, different piston. trust me it's way worth it!
