Yes he says it is a 340, but the motor is from a 1971 I am told. H-code? I don't know.... I noticed it was auto. I would assume 3 speed auto but not sure. The car really looks hot and well kept. Someone restored it. Before I go talk to him, drive it and get into every feature if I get that far in my decision making, I wanted to do some homework on it and make an offer as low as I can without sounding to ridiculous in my offer. I realize I didn't give much information on it but I am just looking for ball park figures.
