The guy says he "knows" it is a 440 & it has at first glance that grungy "original/untouched" look as does the AVS & it has a yellow vac cap on the bowl vent for the hose to the charcoal canister that a 68 car would have. I will check numbers the next time I get over there but the guy says he really doesn't want to come off of it (I may have to put some hundreds in my pocket!). & it is a 2 dr. Thanks guys.
