392 hemi in a duster pics?

Has anybody done this? I ask because I have my 70 duster that I drive and I have 71 duster thats on the project block in a way. I found what rumors to be (and this is a legitimate mopar guy that owns) a 392 hemi and transmission that 550 dollars will buy. the owner is out of the game now days and its setting wedged in some pickup in the back pasture. I think this would be an awesome build up. Input anyone?
