Its only a 4.030 bore because I didnt want to buy new pistons just for a few extra cubes. When these pistons will no longer work I will go with the 4.125 bore.

Basically everything will be the same but I am upgrading the crank from a 50oz scat 9000 cast to an internal 4340 zero balance. Im also going to change intakes from my systemax stage 2 by fox lake to a Victor 5.0 ported by Ron Sharp. Im also planning on a vaccum pump since the Victor doesn't have the PCV in the back of the intake. After all said and done it will probably run the same or possibly slower with the added weight and the loss of bottom end torque from changing intakes. Should be 10.90-11.0's but should be a strong piece.
