Default Re: Project Blown 305

A couple points on the crank plan:
2" SBC journal is pretty small, for strength and for lack of journal overlap. Add a blower and cracks are almost a certainty.
Reducing journal size by offset grinding only adds the amount of stroke that journal is reduced by, not double. 2.2 BBC gives up to .600 more stroke, .300 throw. Welding would allow more, obviously, and/or bigger journals.
7.2" rods stock, easy enough to source longer BBC/BBM spec ones.

Sonic checking any old iron block is a good idea. It's not improbable that it would go .125 over with meat to spare. 5.25 Continental aircraft pistons are light.
