Need info on this block

Shouldn't there be VIN marks on it somewhere though? I know if you bought a block across the counter it had no VIN associated with it. DC was selling T/A blocks with no VIN over the counter as race blocks until the X block was released.

I've never seen an OTC 440, but I have seen a few OTC Hemi dong beaters and they had numbers like that, with out VIN numbering.

Like I said, haven't seen anything like that in years so I may be wrong.

Edit: I also didn't realize it was basically complete. It looks to have a Milodon Super Stock pan on it.
We did not see a pan rail number. But feeling up the front it may have the drilled bosses for a M-code car. Would the OTC block have these mount holes?

I was wondering about the double lines on the heads?

It is definitely a built motor all the bolts head and flex plate are ARP. it looks like they bought a long block and added an intake and manifolds to install it in a street car. From what we could see it looks like it came out of a race car.
