The problem is getting the crank. They are out there but the price is crazy.

Piston prices have come WAY dow in the last 20 years or so. The crank is a much bigger deal for sure.

I'd say the crank would be expensive, and custom pistons aren't too much more than shelf ones. But it would be badass to build it and make it competitive.
