3.58, 3.79, or 4.0 stroke in a 360

Years ago with limited piston availability I chose to run a 3.79 K1 stroke crank (387 CI) with 6.125 K1 rods(with chevy big and small ends) that enabled me to use an off the shelf Diamond Forged Piston designed for a 383 stroker sb chevy. The valve reliefs were relocated for an $8 charge per piston, sure beat paying hundreds more for a Mopar specific custom piston.

However, with today's piston selection, I'd recommend going with a 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.
