383 pistons

This is an extremely vague request . Do you want '65-66, 325 h.p., '67 , 336 h.p.: '68, 335 h.p. or '69 335 h.p. piston ? Or do you want 383 , 2bbl dished pistons or 70-71, 335 h.p.. they all have a different compression height to vary the compression ratio . What head gasket are you using ? These are important things to know .
