Small chamber option with the CID’s starts you off with 56cc. Then mill .060 and you’ve got a 14:1+ depending on the gasket. I’ve got a sbe along with a lot of other guys out there running big compression on sbe stuff. As far as aftermarket pistons go, JE, Wiseco, Mahle, etc allow you get big compression if you wanted.
