Platinum Series Pistons - 4.350 -17 Dished

These pistons are a 4.350" bore -17cc DISHED piston which will work in either a 440 block with our 4.25" stroke and 7.100" rod "512CI" stroker combination, or in a 400 block with our 3.915" stroke and 6.535" rod "470CI" 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. The compression ratios and distance below deck will change slightly depending on which stroker combination you are using these pistons with. Our table below lists detailed compression ratios with each combination.
