572 oil system with A body Hemi K frame & mounts

well i'm still in the ordering game on the pistons , and the machinist hasn't done a clean up bore yet . and yes it puts the thinnest thrust side down to .120 on the cylinder . and the fattest at .152 on the cylinder . keeping it cool might be an issue on gas , could step up to e85 .
That would worry me, what kind of compression u going to run? Be a ***** to blow a hole in the cyl. wall !!
