I was thinking 4 inch (which one of my blocks already has and is common). I would think with special pistons, rods and a little more work to clear the rods on the bottom that a 4.25 crank would work. I know someone has tried or at least did the math on this. What is the scoop on this? I know there might be issues with an oil pan which may need some mods too.
