It is a 350, from the 70's, or early 80's, and probably a 4 bolt main. Heavy duty. From a truck, or station wagon, or high performance. On a pad, just in front of the drivers side cylinder head, there will be a number, beginning with a couple of letters. TO, is truck only. Probably what you have. Good motor to build a hot rod around.
