A bit of Mopar History here for sale on Ebay THIS IS NOT MINE

So they could be T/A blocks.

The T/A block I had came with offset bolt caps. IIRC the guy that I bought it from said those were the only 4 bolt caps at the time. And they were made so they would fit on passenger car blocks.

There weren’t many T/A blocks around even then.

I know he put the engine together in 1974 or 1975. I think it was for Modified Production. He had a set of fully ported T/A castings he used before the W2 came out.

He quit racing when NHRA killed Modified Eliminator. He hated bracket racing.

I agree with you in that even if they are T/A blocks they are used up.

The heads and valve gear is worth something if you don’t mind iron heads

I didn’t see them but if they have a set of W2 stack injectors that would be cool.

Although there is about zero market for a stack injected W2 engine.

Edit: and they machined the oil filter pad off. So at best you’ll be running a remote filter but it looks like they plugged the feed hole from the cap to the block permanently.

That means dry sump only unless you can undo and unplug whatever else they did to run the dry sump.
My T/A block had the same main webbing as the X-block. It was just not drilled for the 4 bolt center three caps . Look at the front of the block down by the main cap in the first picture and compare it to the second picture. All T/A's and X blocks I have had were like the second picture

Also the x block was almost twice the weight of a standard block due to high nickle content in the iron. And also still heavier then the just as thick T/A
