Well, I do HAVE a 440 block still sitting in my garage... Should still be easily salvageable, too, as I've kept it pretty safe and dry. And in fact I think an original 440 'Cuda isn't what I want anyways, since I still insist on having a round-taillight car, and if I'm correct, they never came with a 440 option, right?
As far as adding the 440, most 727 transmissions can't handle the 440 if you do any decent performance boosts on it, such as a mild stroker kit or something - isn't that correct? I know you can buy aftermarket, specialty autos for use with a high power big-block, but YOWZERS they're expensive....
I've found a few cars for sale with a 440 upgrade and an auto, but seems most have had hideous paint jobs done to them or they simply want way too much money for them.
