Could this have been a M code block? Absolutely all numbers/markings have been ground off the block. Thanks. Kim
I’ve had a few 383s like that. A 440 A body has a different mount. KimI thought on the M code and C body blocks.....as well as 383 A body blocks those bosses next to the oil pump were drilled and tapped too.
So then the holes on my block must have been put there for something else at one time. Kim

Off topic reply warning!The holes in the first block are like the 383 A-body holes, BUT if it's an RB it's likely a late motor home block. This is a late 440 in a class A.View attachment 1715395016

straight axle gasser motorhome?
Guys, That’s what I’m asking. The 2 holes above the oil pump boss are ground off and rounded off curving back to the outside of the block. I think they may have been bosses, but not sure. Hopefully someone that knows these things will chime in. Kim
