This is probably not a very good idea, as the 302 ports are circle shaped and the 250/292 is more square shaped. Could maybe be done , but will take some fabricating of port adapters and cutting/welding. Have you checked out Patricks intake for the 302? I use a Clifford WH, not sure if they still got them, make a call. Check out with Larrowe and sons too.Theese are single 4-barrel carb intakes.
