Realized I didn’t describe anything. Well the previous owner took out the 383 & put in an RB stroker defined as a 494; probably a 493. He also had front discs installed, new gas tank & air shocks. Rear end has 3.73s.
I’ve got a few pictures, even a short video. Apparently even one of them are too big to load for now. I can send them to whomever anytime though; great driver!
