Picked up a couple complete motors yesterday, both free and supposed to run, Ill be putting them on the test stand today and firing them up.
Question is one of them has a double sheive and then another shieve in front of that a little smaller diameter with provision for 3 narrower belts. What were those for? Is that a supercharger pulley?
One is a B9AE with the green Merc valve covers so hopefully its a 312, however they both came out of trucks.
