454 +30..... 6.135 rods..... 345cc dart iron eagles... 420 mega blower 6.5psi. The motor had 2399 speed pro forged in it prior, just thought it was weird having a dome piston on a blower motor. Anybody have a good piston recommendation? All help greatly appreciated!

Thats the piston that came in the 454 mag's. A typical "forced induction" piston, for a 454, is a flat top. Or, if you really wanna drop static down, to say the mid 7's, a dish.

Here is JE's blower piston for that combo
