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 FLAT TOP FE FORD 390 PISTONS
Forged Stock Stroke and Stroker Ford 390 Piston Sets
- Will work with OEM 390 - 428 FE heads or Edelbrock aluminum FE heads
- Can be used with small nitrous kits, pistons made of 4032 alloy
- Top ring is down .275" from top of piston
- Valve relief depths, dual symmetric, .225" deep
Explanation of Diamond Flat Top Ford 390 piston specs listed below:
- Bore = Finished cylinder bore size in inches that piston is designed to work in
- Stroke = Crankshaft stroke in inches that piston is designed to work with
- Rod = Connecting rod length in inches that piston is made to work with
- C.D. = Compression Distance, also known as compression height. This is the dimension, in inches, from the centerline of the pin bore to the top deck of the piston
- Wt = weight in grams of one piston
- Pin = pin diameter in inches, all pins 2.930" long, premium 8620 material
- CCs = cc displacement in total of the valve reliefs is -6.0cc
- Compression Ratio = static compression ratio comparison of piston when used with different volume cylinder head chambers. This is based on using a 10.1cc displacement head gasket and with the piston .011" to .015" below deck at TDC Deck height of 10.170"
- Ring Set = part number for a complete engine set of plasma moly file fit piston rings, ring grooves are 1/16, 1/16, 3/16
- Piston Set = part number for a complete set of 8 forged pistons, piston pins and spiro locks
