Is there a simple/easy way to ID a 273 engine vs 318?
FWIW - Though to hard to read under the paint but shown below are more ID numbers that contain the displacement of the engine under the drivers cylinder head. If you look hard enough and expand the picture, the numbers “360” are there on the right side.
Normally a bit hard to see due to heavy paint, like below or just years of dirt and grease, it’s just easier to go look above the starter.
