If the car has a working tachometer - then the distributor has to have been out of a 55 /56/57 'bird. A 239 is a "tang drive" motor - or it would have to have had a later oil pump stuck in there........ If the distributor is from the 55 / 56 models, then it would be a Load-O-Matic and the aforementioned Holley carb would not provide the necessary source vacuum to run the distributor's advance system. It would also need an adaptor to fit on a early four barrel manifold. I'm not trying to poop on the parade - but some stuff needs sorted out here......

Is there a chance this is a 272? - distributors would then mate and drive the oil pump. And there are "A" 4bbl manifolds on many 272's. The fitting of the later style Holley - with a Load-O-Matic is usually a recipe for trouble - so is it the later version or the T-pot?
