This oil pump is a Butler Performance exclusive! This pump has been completely remachined, blueprinted and tested to be what we feel is one of the best Pontiac oil pumps on the market.
We now also offer this same PRO pump in a 60-65 psi version for the those of you that want a high quality oil pump but have a milder combo that doesn't require 80+ psi of pressure- See part# BPI-M54DS-PRO for the 60-65 psi version.
anti-gall/ anti-cavitation dimples in bottom of both gears
Extra thick diamond lapped .250" oil pump plate
Tops of Gears machined with 360 degree oil grooves to prevent galling against plate
