and if cut the pistons how many thousands did you cut them or and what clearance did have???

I have a similar setup, heads are 2.5 and milled to 59, just a 224/230 cam though. I got away with just .064-.067 clearance though on intake side. I got a strong feeling you'll be cutting.. I don't have any numbers yet but I can say that the car is a torque monster with the 4k stall. Definitely good for a low 7 1/8th pass I believe.
