Trivia: How much did the 440 option cost for a 1968 Roadrunner?

u never say never with Ma Mopar as we’ve seen many times over cars that c as me out of the woodwork and been documented. Then there is others claiming to have 1 of 1 that was never been documented or proven either way yay or nay. It’s buyer beware out there now more than ever as ppl are trying to pass of clones/fakes as the real thing and some are actually getting away with it! Kim
