Does not say if it is from the "Butter Block" or "post post butter block" era.

My butter block was ordered Aug 2005. The early blocks were cast at:

https://www.tri-cast.com/

They can be identified by a Triangle logo cast into the block near the distributor hole. Within that triangle are the initials "TC".

Coulda been worse. At least it did not window the block.
Ad does not feature the crankshaft so it is either totally destroyed or the seller is hanging on to it for another build?
Looks like jugging it would be the way to go if the buyer did not want displacement over 500" .
Have to have it wet magged around all the impact areas to look for any possible hidden fractures.
If aluminum rods were in use in it at the time it let go the damage would no be as severe?

Mr. Pontiac could make this the foundation for his next secret weapon bucket list build.

I can tell you in addition to the block hardness and wall thickness issues that the rear main seal groove was so out of whack that alone made the block unusable in our opinion. The groove was too deep and wide. It would have taken modifications for a fix. And I know of others the same way. There are pictures of my seal groove posted on PY if one wanted to dig for them by searching.
