Ready to order pistons and rings for this 400 based stroker motor. 4.25 stroke, 4.402 bore (.060 over). Will be using the ICON flat top pistons, IC823-060. There is a Total seal moly ring set, file to fit, that I like. CRG 3690-45, with 11 LB oil ring tension. Also available is CRL 3690-45 with a 16 lb tension. Not sure what to use, but leaning towards the 11 lb ring set. Any ideas? What have you other 512 builders been using? This is a Drag race only motor. Thanks
