I have a '66 Hipo block, harmonic balancer, and intake that seem to be parts born together. It does have a San Jose Mustang VIN, but before we get excited, it's a coupe. (cant remember if I looked into trans am coupe date codes, but I believe i did....hmm.) Anyway, I'll post some pics. Take a look at the "K" in the VIN stamped. A friend said it looks like they made the K with a Zand and 1 maybe. Just curious if anyone has a similar K stamp on a Shelby or seen one like it anywhere.
