Diamond Pistons FE Ford 390 Pistons

Diamond pistons are available in many different sizes to fit a variety of Ford 390 FE engines. We sell these pistons to fit both stock stroke and stroker engines, as well as to fit many different bore sizes and different compression ratios. These Diamond Racing FE Ford 390 pistons are all high strength 4032 forged pistons. They offer great strength as well as light weight. They offer improved engine performance and much greater durability than a stock type cast or aftermarket hypereutectic pistons.

Diamond Big Block FE Ford 390 pistons provide greater strength, reduced friction, better piston ring sealing, faster acceleration, more horsepower and torque in your high performance street, strip or race engine. We offer the entire line of Diamond forged pistons to our customers at great discount pricing and we are happy to provide technical assistance if you need any help.
