I think I have a pic of that casting number. Is this it?
 Here's the pic after new oil PSI gauge installed. I put the nylon line inside some vacuum hose for some added protection.

It's blurry but it appears to be 500557? Also, this pic from your album looks like it may have an additional motor-mount bolt hole on passenger side:

Yep.
Now you need to verify what is inside. May be able to id stock or aftermarket crank by rear hub? I personally don't know if there is a definitive difference. Stroke should tell the tale. You should be able to measure stroke thru spark. plug hole. I hope someone didn't swap the short block out on you when RMS was replaced. The two digit alpha codes were reused a bit. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
