Anyone used a V6 Magnum in an A-body?

I was thinking of picking up an early A-body, something like a 66 Valiant to use
as a daily driver.
Was also podering the idea of dropping on a V6-Magnum and 4speed auto out of a later model rwd dodge, probably a dakota doner. Seems like it would a good engine/tranny combo for that size car. I'd also want to retain the fuel injection

Anyone have any experience with a swap like this ?
