318 Magnum swap?
he is high on price as you only want the motor. I have a 360 magnum 4 speed in my 68 valiant so fire away with any ?'s that you have. we will be happy to help you out.
I would do the carb over fuel injection but that is just me. You can buy a whole truck with a burned up tranny for that price. 166k if the tranny has not been rebuilt it is probably close to the end of its life. There is something to be said for knowing the history on the motor but 500.00 is what motor is worth IMO
