That sounds more like a casting number than a engine number. Engine
number should be stamped on a pad just behind the distributor. The first 3
digits should be the displacement.
Unless it's a Canadian GMC - which had Chevy stovebolt engines. If it's
a GMC it will have 5 freeze plugs on the intake side.
