Decked .050 would still be able to read the stamping.

The ad read 'decked 0.005" ...'   which isn't much, but it's clear the stamping is gone.... so it was a much deeper cut, probably with the intention of removing the original stamping (and support his current claim)...

Probably wasn't a DZ block to start out with.

My mistake, .005 not .050
I'm told if a numbers block must be decked it can be done in a slight angle to save the stamping.

A machinist can also stop the machining short of the stamped deck....

Probably not on  CE block. If it was an original block it could have the VIN by the filter, but that wouldn't tell you it was a 302

Could there be a vin stamp on oil filter boss?
Kerns is in my town, as far as I know is well regarded as a long-time speed shop. If anybody has questions maybe I could stop by and take a look for you?

Actually the CE stamping was only used for 'warranty replacement engines; not OTC blocks/engines..  those were unstamped.

I stopped last night and checked it out. It had no VIN that I could detect. Otherwise a decent-looking block for a project. Auction ended - no sale

Hey--are these things really worth all that much? I have one that I was just going to use in a 302 hot rod build....is that not a good idea?

I don't think a 4-bolt block (prior to machining) is worth that much without some 'original stamping' value (which that one did not have).   now..  IF the machining (boring, line honing, etc) had been done and done by a good machine shop you trust, then it's well worth $500..  as the machine work would cost close to that.

I have a 4-bolt main 350 block from early '70's that had been in my shop since early 80's which I disassembled late last year and had the local machine/speed shop check out (was thinking of a 383 for my EC)..  no cracks or other problems; std bore which the machine shop told me would be good with an 0.020 overbore which I'd put on someone for $200.. OBO...  :)
