MO

Willing to bet money on it. Top tips of the M are visible, lower half of O is obvious to me.

You guys are probably right about the pad stamp being mutilated for unpure reasons but who really knows. Its really a shame since the rest of the engine is awesome. It is still standard bore and looks like it will stay that way. The crank is even still STD/STD. It was greased up and stashed away 30 years ago.

As far as the suffix code goes, someone mangled it long ago for unknown reasons. That is why I never thought to look for a VIN by the oil filter. The chances of it being a COPO block is slim compared to other applications. When I was taking pictures, I realized it was not a CE block since there was no assembly date on the starter mounting pad. Then I thought it was strange there was no VIN on the pad and looked at the alternate oil filter location. Here is the pad:


Thanks again,

Jason
For those with questionable stamp's Jason's closeup pics show outstanding broaching marks!

Top of it looks like an 8 but I can see a horizontal stroke at bottom that could be bottom 2 , I will defer to your superior knowledge of dates of these copo blocks. I pointed out the tips of the M with red arrows.

Thank you all for all the input and detective work. For what its worth, the crank has a pilot bushing in it for a manual trans. It sounds like the car is not known. I will get the engine posted in the classifieds.


Thanks again,

Jason

Yep, T0828M*. That date makes the most sense for that VIN.
