Chevy SBC 350 Oil Flow Restrictor Kit The Speedmaster shift selector shaftWhen roller rocker arms are installed, along with a mechanical lifter cam, the amount of oil flow required to the valvetrain is greatly reduced. Installing a Speedmaster oil restrictor kit will limit this unnecessary oil flow. These kits reduce the power robbing windage created from the excess oil draining past the rotating assembly and keeps the oil flowing where it is needed most, the rod and main bearings.
