I have a 454 512 block, standard bore 4 bolt main. Just wondering what a bare block is selling for. Thanks for any information.

Can you post a few pictures of the casting date and the stamping on the front of the engine? It will determine what you have. It would be worth more to the person that is missing their original block. Standard bore is a plus too.
what is the casting date?

Are you able to get a picture of the VIN stamp and suffix code on the front of the block?

The VIN stamp on the passenger side front pad plus a picture of the oil bypass area like this.
Could be worth quite a bit if the VIN hasn’t been machined off.

There are no numbers, that area is smooth.

It’s a LS5 out of a 1970 Corvette. I would post it over at the Corvette forum to see if anyone is looking for that VIN. Carefully clean this area, don’t sand or grind on it. Also pull the valve covers and get the casting numbers and dates off the heads to see if they match. You could probably get a really good amount if the heads and rotating assemblies are original.
I can make out 10S415xxx which is a Corvette VIN

We’re did you see this number? From the pictures I provided.

Based on the two pics you provided in post #8 that is not an original 4-bolt main block fwiw. The two pipe thread fittings above the oil filter boss are the wrong size. Look at the pic @70SSOBSESSION provided in Post #7.

Yes the bellhousing flange. It’s the VIN for the 1970 Corvette that the engine came out of.

Only the Corvette vin started with the 4. B body would have a 1 after the “S”

Curious if the heads match. Are they GM oval ports?
