It was all orginal when I bought it, I have changed the Carb, intake, Wheels and tires. The inside is like new, has working factory air. It's a 318 car with the 904 tranny, it runs and drives great, I could drive it everyday if I wanted to. The guy that put the intake on said it was as clen in the motor as any car he had seen, said there wasn't a speck of sludge in it. I have been looking for one for years and this one showed up 35 miles from my home. The seller was moving to florida and didn't want to move it with him, so he shot me a price and i bought it. I love it!
