Hello,
I just bought a 56 gmc pickup.
Now i'm trying 2 indentify the engine, but i'm a newbie so can someone help me with some directions.
The block is green underneath the red paint so i think it's a pontiac block.
Some numbers I found are:
1018PY2103 (Serial number)
A756H16416 (Block front of the passengers site)
GM-522010-10 (cilinderheads)
D236 (cilinderheads the 6 could be a five difficault to see)
GMC-2331212-5CC (back of the block passengers site)
3-4-55 (back of block drivers site)
518688 GM-4 (Exhaust manifold)
CA-55-5754 (Is the plate on the hydramatic)
