The motor was freshly built when I bought it. Said he changed his mind after it as built and had a 440/6 done and put it in.

Wish I had a sonic tester, love to see how thick the walls really are.



What are the pistons , 2315 ? they will be about .015 in the hole , but the block appears to have been decked already , which is why that ID pad is blank.

The only downside to those pistons are the lack of valve reliefs .

I would just run it as it until something causes you to have to take it apart.
