Your prolly looking at a rebuild however it did run when pulled… Im pretty sure its a 4 barrel carb that one is from a 1965 interceptor edition tbird. Was a power house has the auto trans attached to it… everything is complete like it would sit in the bay… I dont know what its worth to ya but i figured it was close in yr and would do better then sitting on a cart in the garage… Ive tried to confirm with numbers as to it being a 428 but not very good with that. That 65 came from the factory with the 428 originally thats fact just insuring it wasnt replaced yanno what I mean… Ive been told it could be a 427 or 429 aswell either way its a bigblock.
