Oh dear God! 318 stroker
One other noteworthy mention if you use higher compression height 1.72 CH sealed power pistons. If you’re planning on using iron open chamber 360 heads, you can run at positive deck like a 340. But you do have to start carefully planning for piston to valve clearance and having a solid plan on what compression you’re planning on. On that note, I’ve been collecting parts for the same type of build using some full float 318 rods and some eBay Zollner pistons with 1.746 CH, steel expansion limiters, and over .400 crown thickness. Going to get them cut for snap rings for pin retention and cutting a large dish similar to a 360 piston in the crown for piston to valve clearance and to keep the compression in check.
