If you can find the original blend, GM's EOS was commonly used for this purpose. However, because it was marketed as a lube supplement, the amount of zinc and phosphorous exceeded current lube oil specs. Because of that they relabled EOS as an "assembly lube". The new number is 88862587.
I think the current product might be okay, but according to engine builders, so are equivalent products from Crane, Torco, etc. I'd direct you to the massive oil thread here on PParts, but that might cause you to hurt yourself to read the whole thing.
