Supposedly PPG 34560 is a good match for 54-63 truck engine gray. You'll have to guess that this is the same gray used on V-8s.
Bill has posted above: "Plasti-Kote #202 Universal Gray engine enamel is as "correct" as you'll find and it's easy to find locally"
Jim Carter's truck engine gray is lighter than the pre-54 engine gray/blue (as sold by the Filling Station for 29-62) and I think it is a good match for 54-63 engine gray (
Carter lists it for 29-62).
