GM Oil Pumps
High pressure performance oil pump with billet Shark Tooth gears and a chromoly shaft.
  • Fits GM 262 to 400 small block engines
  • High pressure, standard volume
  • Doweled cast iron housing, phosphate coated
  • Chromoly steel shaft included

    At sustained high rpm a stock pump can flex at the cover and lose the tight gear clearance that holds pressure. This pump answers that with a doweled housing and cover, billet helical gears and a chromoly intermediate shaft, so it stays together in a small block that sees track or heavy duty use.

    • Billet steel Shark Tooth helical gears.
