I have a 302 long block setting in my shop that has been there for a while, came out as a running motor, but I have not messed with it in while and its stuck, don't know why maby a valve, or a little rust in a cylinder but it has been inside the hole time. Might be a good one to bore and re=build no intake. 200.00, hate to scrap it. 417-236-5494 located near Crane, Mo.
