Aluminum blocks don't have problems with cylinder wall thickness, like 351C blocks do, because they use iron cylinder sleeves. Just order your new aluminum block with the cylinders bored to fit your pistons. I ordered my Fontana aluminum block with a 4.125" bore but I could have gone up to 4.180".

Mike's engine is stroked to 408 cubic inches & was purposely built to rev to 8,000 rpms.

Stroked engines are famous for cylinder wall thrust wear in conjunction with piston thrust side wear only exacerbated by 8,000 rpm revving.

I would bet 7/2 that Mike's current piston's will show "out of round" wear beyond tolerable/allowable specifications...Mark
