B&M 420 Mega Blower, comparable in size to an 8-71 Supercharger but designed to be more efficient and responsive. The blower was professionally polished and serviced by Al’s Blowers, and it also received an upgraded rear bearing kit during the rebuild.
Since the rebuild, the unit has seen less than 10 hours of run time, with new bearings, upgraded rear bearings, and fresh oil installed. The Teflon rotor strips were inspected and left in place because they were still in excellent condition
