As others have said, the 472/500 is a nice engine, very torquey. The 390/429 isnt really that great of a engine. I had a 67 Coupe DeVille with a 429 and it wasnt anything to write home about, drove a 68 Coupe DeVille with a 472(same car differnet engine) and that thing would smoke the tire(s) as long as you kept your foot into it, night and day difference.
