It was originally a 2 bbl car - H fifth letter. I just purchased the Wagon and I am in the learning process. It currently has an aftermarket intake and a Holley with a blown power valve. I have a Q Jet which has been rebuilt and a factory 4 bbl manifold (GM # 392713) from a 1969 350 which came with the car. My thoughts were to go with the correct 1972 4 bbl manifold ( I believe 3797771 is correct) and stock Q Jet.
