Well It Finally Happened

I'd go with a blown 408!!
Icon pistons part# IC982 Has a -34cc dish and will result in a 8.8CR with 65cc heads. It's a forged 2618 piston perfect for boosted applications. Off the shelf pistons save money too.

Good head gaskets, head studs are a must. Full groove main bearings will provide full time oiling to the rod bearings.
