Re: Choosing pistons to complement GT40P heads
The best set that I had were some custom JE's that along with some creative milling of the heads netted me a nice 13.2:1 compression. That carbureted GT40P motor made 465 on th engine dyno with a .500" 239/244 camshaft, Holley 650 carb and Weiand Stealth intake. Those heads were unported and had stock valve sizes! Seriously though if you're not planning on an all-out attack for HP, I'd consider a forged piston out of Probe's SRS line-up. Good quality, exacting tolerance for a modest price. Beyond that I'd call Wiseco for a two-relief stock replacement, un-dished.
