Oh dear God! 318 stroker

359 Cubic Inch

Molnar 3.58" 2.100" SBC journal crankshaft
Molnar 6.200" SBC rods
4.00" Chevy 350 pistons with a 1.565" compression height. -.025 below the deck,

So many choices in 1.560" & 1.565" compression height SBC pistons allows for an almost infinite choice in compression ratio.

Or just buy a $400 360 core and be done with it.
