[Mach 1]

The summit blocks are ready to go, cam bearings, freeze plugs installed. You need to get your stroker assembly balanced and the block bored over .030 if you went with a kit that requires it, or you can get the block bored .030 over and notch the piston skirts for clearance yourself.

or you can get a 331 stroker kit that uses the standard bore and might not need notching, requiring no additional machine work. Shop around.
