two 354 hemi's

Cool. Then the truck engine in particular is probably what is called an "extended service" engine. Very thick casting that can be bored many times. Most of them can go to 4". Of course sonic checking is a must.

There was a rumor that those cast with a large "W" in the side of the blocks were the extended service engines, although I don't think that's ever been substantiated. I sonic tested my 331 and verified that it is an extended service block, but since it was in such good shape, I left it at .030" over.
