Got my 350 block back from the machine shop. I noticed that where the mains meet the block, with the inner bolts torqued to 75 ft#s, the outers to 65,
the seam can be felt. They arent way off, but enough to snag a finger nail on. I have an untoughed 305 block and you can run your finger all the way around the aera where the bearing fits and can not feel where the cap meets the block at all. The block was suposed to be align bored, you can see where the mains were at least honed because you can see the cross hatch pattern. Should I take it back to the machine shop or is it OK to start building like this?
Thanks,
Mike

 

First make sure you're using the correct cap's, they should be numbered, or "dotted"...also make sure they are oriented correctly.

Also possible they gave you someone else's caps....

Are you sure the edges of the seam aren't just rounded and that is why you are feeling them? Does the cross hatch look like it matches for the top and bottom halves? As mentioned, make certain you have the right caps on the right mains. If you are still uncertain take it back and show them what you are seeing.
