[WANTED] Mopar race block, prefer X block

[dodgedude]

I am looking for a block for a friend. It must be an X block 318 casting. May consider an R block, with the factory deck height. Need block only but may consider a short block assembly if that's how you need to sell it. Please see attached pictures. Prefer that it is a 4 bolt main with NO DAMAGE and as small of a bore size as possible. These were not factory production blocks. They were sold through direct connection (now Mopar Performance) in the 80's. I do not want a factory 318 block. If you are unfamiliar with the X block, pick up a Mopar engine manual and check up on it. The had filled pan rails similar to the TA blocks and thicker deck and cylinder walls.

The pictures of the one attached is what we are looking for.

Thanks
