What the heck is that

Back in the mid to late 70s, I fabbed up something like that for a 64GTO/389, by customer request. I didn't think it would work, but that is what he wanted. I built the auto in it as well and it had a pretty fancy 2-speed TorqueConvertor in it. I think that is what saved it cuz in the end she was a pretty good street blaster. My rods were not that overkill tho,lol.
