Not sure if anyone can help but here goes... I've owned the car to this engine for 30 years. I was told it was originally a 302 car... It had the ralley stripes and z/28 badges when I bought it.. But I found this orphan thread which shows it being an ss car.. Mark sold it (somewhere between Monroeville, NJ and Carlisle, PA) and dropped it off on his way to Carlisle...
If anyone bought a 350 68 camaro engine from Mark or junkman60 (from Monroeville NJ) or firstname.lastname@example.org
with the 18n457232
castings I would really like to talk about buying this engine from you.
