I have a complete set of new Ross pistons, the compression height is 1.865, pin is .990. They were ordered for a 4.125 stroker engine.

Can they be installed in a stock stroke 400 or 440 block, if so what rod?

Or do they have to be installed in a stroker engine?


They will fit a .030 over 400 block or .055 over 440 block.
