Apparently the same place that can offer custom built heads, also offers lower compression (10.5:1) forged pistons and forged rods.

At that point, assuming conservatively around 3k labor, for heads, rods and pistons install, and around 6k total cost.

I could easily push 12+lbs of boost(assuming the 1.7L eaton blower doesn't shit the bed above that) and be well into the 500+ WHP numbers. Likely 550+.

At that point I have no choice but to spend an additional several thousand on a 8L90 trans to deal with the power, as the 8L45 that came with the car cannot handle the 390WHP I'm putting down now.

So realistically I'm talking near 10k to go from 390WHP to 550+WHP.

That's a third the cost for a Texas Speed destoked LS7 that makes 700+ HP all engine, with a mated automatic trans, and revs to an astonishing 8500RPM. Another 1300 more than my little 3.6L.

I have choices to make here.
