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.



yea.. 2315's are in it. The cam that came with it isn't too crazy (Comp XE-274), so no valve reliefs shouldn't be a problem.
