The earliest versions of the Chevrolet Small Block (SBC) and Big Block (BBC) engines featured a unique oil filter sealing surface that creates a challenge when trying to find an appropriate oil filter take-off or sandwich plate. Improved Racing's spacer kit properly adapts to the SBC/BBC filter sealing surface, making it simpler than ever to install most remote filter take-off and sandwich plates on these older engines. The assembled kit comes with a machined aluminum adapter/spacer, a robust O-ring seal, and a steel 13/16"-16 threaded oil filter extension screw.
