302 casting on a set of 318 heads

H814CP is the taller stock cast type out there right now. Same aftermarket pistons as for the 5.2 Magnum. A tad taller than waht slantsix is referring to. Around 8.9 SCR with .028" head gaskets and 62 cc chamber heads on an LA. No eyebrows is part of that CR..... so keep an eye on P-V clearance; that cam you linked probably is a slow ramp cam and does not have a ton of lift or duration, so that helps.

Looking on Rock here H814CP piston for 1993 D150 318 is showing 1.755 CH Flat Top. Without the valve reliefs, this should help bring up the compression closer to the 69 318 pistons 1.772 CH that has valve reliefs.

Tallest CH 318 aftermarket piston so far: H814CP at 1.755 CH flat tops.
