Picking Up 340 Short Block - What to Look For?

$678US is a bit high for a good 340 block & caps. )But I've seen rusty pieces of junk for a $500 asking price!) What you can find that is decent is a factor since you need a specific block. We shopped around and got lucky and got a .005" over 340 block in good shape for $300... not likely to ever find that again, but I'd expect to find something pretty good for $500.

Standard bore is good to have! You can get .020" over pistons and save the block for a coupla more overbores. But verify.... supposedly being stock bore has value.

No way to know of it is cracked or not if not properly tested. Any info or guarantees being provided?

Any chance this is coming our of the NW Ohio area?
