I have what I think is a 250 with integrated head but first, are all integrated L6 engines 250 cu in? It has a 2 bbl carb with a distributor #1110755. Any idea what this engine is out of? Are there serial numbers on the block somewhere? If so, where? Or is there aother way to tell what vehicle this is out of? Gettig parts are a bit tough if you don't have the application.
