1. When looking at the motor from the front..... on the rear left hand side near the sump, you will see the numbers XE192540 and you will also see the numbers 302.
2. Once the sump is removed, you will notice that the main caps are 4 bolt ones, but are bolted up with 2 bolts. Also through the caps, you will see that the block has the holes pre-drilled and threaded for the 4 bolt set-up.
3. Also on either side of the block, you will also see the extra casting for the cylinder walls.
