i'd get the numbers off the rear of the engine block to verify that you do indeed have a 283 DO THIS BEFORE ordering any parts for the engine

Keep in mind, the casting number and block date code are raised since they were part of the mold. The engine ID on the front pad are stamped.

Am I ever grateful for these tips. Turns out I was given some false information when I bought this pickup. I checked the numbers and she has a 327 in her instead of the 283.
