My 273 build

"thinking about using a 4" Eagle crank" The point the guys were trying to make is that the Egge pistons are for the stock crank. A 4" stroke crank will require different pistons that no one makes. They will need to be custom made.

I think Cadillac? made pistons in or close to a 273's bore with a shorter compression distance? Maybe do some research and the math?
