These pistons are a 4.375" (.055 over) bore flat top piston which will work in a 440 block with our 4.15" stroke and 6.76" rod "500CI" stroker combination. All our platinum pistons use 1/16, 1/16, 3/16 ring pack for less frictional loss, and weight saving, full floating .990 pin size. Our table below shows detailed compression ratios:
