This is a fresh conversion of a hard to find blower. It's been totally gone through and machined for hot rod use. Rotors are triple-pinned, front plate enforced, gears tapped and cleaned, side flange removed, new seals, GM bearings inspected and sonic cleaned, (not Chinese), supercharger supply rear plate, drilled for pressure relief included and a fresh coat of Gibbs. This is the perfect size for a small flathead or little motor. This size is very hard to find and this one has great rotors, ready to ship. 316-393-1105
