What's in the Box

We have been selling Keith Black pistons for years and now offer their premium new generation forged pistons. Starting with 2618 alloy heat treated to high-strength T-6 specifications, these give you the best value for the money. Exclusive V-ribs add strength without adding weight and allow maximum cooling capacity. 

For Chevy 400 c.i. (4.125" bore x 3.75" stroke). Use Style C piston rings (1/16", 1/16", 3/16").

  • High ductility 2618 alloy
  • Dual forced pin oiling on most applications
  • Lateral gas porting on higher compression ratios
  • Fully machined with deep valve pockets
  • Second land accumulator grooves
  • Top land mini groove technology
  • Diamond finished skirts
  • Triple wound spiral locks
