Brand new full set of eight JE forged pistons for a standard bore 400 (4.125") with a 6" rod. These were a custom run that is desireable because the oil ring does not invade the pin hole which is typical in 400s with 6" rods. The ring pack was narrowed to accomodate this feature. The ring package is .043, .043, .118 (3mm). This thin ring package produces substantially less drag which means more available horsepower. These pistons cost $850. I'm selling them for less than 1/2 the price. Pictures available upon request. $375 plus shipping.
