5.9 slt plus Durango donor for 74 duster

Sell it. The Durango, that is, if it is in overall decent shape. Then find a 5.9 to buy and use the leftover cash to help fund the little things, like the carb, intake, distributer, motor mounts, etc.....
It runs good and the body on it is in decent shape though The interior is a little rough. I honestly planned on using the factory fuel injection from whatever vehicle the motor came from. I know how this motor runs and know it doesn’t make any weird noises. I’m still on the fence about it but I’d really like to get my car going again so if it’s a fairly simple swap I may go for it
