As I recall, all the 57 Packabakers came equipped with a McCulloch VS57 (VS for Variable Speed). The pulley was opened up by a kickdown switch that changed the pulley ratio and caused it to spin at higher RPM at full throttle. Only the 58 PackHawk had the blower. They are pretty reliable when upgraded with new ball bearings and modern bushings. Not sure who is doing them now, but in the past John Erb and Ted Harbit rebuilt and upgraded them. The later Paxtons are basically the same but single speed.
