360 crank in 318 block
Use the low compression truck piston (for example the UEM 1278 or the FM LC371P,has a small dish also at 3" x .040), these have a comp. dist. of 1.658". These will still end up with a below the deck height of 9.571" even in a Magnum block it's still below. Of course there's no valve reliefs so cam selection can't be radical. Now for the crank, .310" thou off the mains and reduce the slinger and oil seal surface size too. The counter weight remove .170" thou off in an off-set grind of .500" thou, vertically opposing each throw of the crank, this only removes the material in the portion of the counter weight where the underside of the piston would/ could come the closest to contacting the crank. This will need to be done on 6 of the counterweight to accomplish the necessary clearance. Chamfer the edge of the weight accordingly, and then balance.
