I have this motorcraft looking 4 bbl that has ECZ cast in the side that most likely came off a friends dads 57 but not sure if it was a 312 or a 292,of course it does not have a tag and from what I have read here that the 312s had a holley and I think the 57 I had years ago that supposively had a 312 also had a holley so was there a 292 4 bbl motor and what carb did it have .

Butchering up everything I can get my hands on in Dayton Ohio
