i have a 250 sittin in the shed on a 64 chevy frame out of a 84 chevy pickup last time i tried running it something wasn't right so i don't know and then dang near started the truck on fire (dumb gas in carb and leaked down the side and no exhaust) but its one of those dumb ones where the head, intake, and exhaust manifold is all one piece but its set up for a 2 barrel carb (one primary, one secondary (like a 4 barrel cut in half)) and dual exhaust
