Maybe it was. I don't know much about the 70's years... The guy put a mild cam in it along with a Edelbrock 500cfm 4 barrel. Distributor was replaced too with one of those fancy aluminum looking ones... blue distributor HEI cap... so I just figured it was converted.
He used to pull a trailer with it from Colorado to New Hampshire so it was built up some.
