Mise well bore to a 440 then get another crank it be about the same price. Last edited by mopar muscle7271; 03/31/21 03:25 AM.

Do you still have your 426 wedge specs when you had them made custom? Probably less $$ than 383 pistons and a stroker crank and then you also get lighter pistons with decent compression, better rings and valve notches. Last edited by GomangoCuda; 03/31/21 01:14 PM. In theory, there is no difference between theory and practice. In practice, there is.

I don't recall, I'd have to look it up. The billet valve covers probably cost more than the pistons. It wasn't a cheap build.
