349 ci stroker, look at .030 283 chevy pistons for a .005 over bore, 283 .060 pistons for a ,035 over bore, but pin holes need cut bigger, skirts need clearance'd from crank throws and then valve notches are off and need machining,..then balancing this hole deal, cheaper ways to do better! dad always said a hard head makes a soft ***, good luck!
If this legitament, I have the mopar con rods 6.123” with Chevy-sized wrist pin journals as well. But you would ONLY have to pay the machinist to angle in some correct-angle valve reliefs into the pistons.
