It's not on the block, but my truck has a repair tag on the valve cover.
I have not checked the serial number to see if it's original, but I suspect it's a later engine, not the rebuilt original. Current color is grease black.
Grease black (dirty oil black) is as close to the description of the original paint color as I have ever been able to come up with. The description in print is called "blue gray".
They can call it whatever they want, but the original blocks with paint still on them did not speak "blue" to me whatsoever.
I have seen a very original 55.2 235 which still had almost all of the shiny original paint under the greasy, oily dirt. Now that color has a smidgen of blue tint to it. It did not match the color of the greasy, oily dirt like the AD engines that I have seen.
