390/428 "FE" Inverted Dome
For the first time ever, our race-proven SRP design is available for the Big Block Ford "FE" series. Available for both stock stroke and stroker applications. Bore sizes for the 428 block are set at .025" over to allow the use of popular file-fit rings. These pistons offer thick .250" top ring lands for use with limited nitrous or boost while still offering substantial weight savings. Wrist pin diameter is .975" for part numbers designed for 6.490" OEM rods and .990" for part numbers designed for aftermarket 6.700" rods (see footnotes).
Includes: Pin#: 975-2750-16-51S (Footnote P) or 990-2750-15-51S (Footnote E)
