Thank you TorOrange! I had no idea Cuda and Barracuda are two different models!...
I was the same when I got my Challenger, had nooooo idea what a Challenger Rallye was, only knew it was challenger, never mind about the different years and models!
I'm sure it's an exciting time for you. As 74challenger03 mentioned, do you have any pics? Show us pics or the exterior, engine bay, interior, underside, trunk.
Looks for rot/rust in the floors, trunk pan, frame rails as with any old car. Vinyl top? Might be rot there too. Engine smoke? Run smooth? Any crud on the rockers if you look through the oil fill hole on the valve cover? Any of the eninge oil look milky? Tranmission shift ok? Just the general run of the mill old car questions...
Don't think that's the factory color for that year, don't think it was offered, but it's a cool color so who cares if it didn't come from the factory like that. Can't tell for sure unless you decode the fender tag under the hood.
Any idea when the 440 went into it? As mentioned by TorOrange, that's not the origianl engine or original tranny as it has a big block tranny and only small blocks were offered from 1972-1974 in Challengers and Barracudas.
