I am looking at getting a Scout II and am unsure what motor to go with. I would like to know more about my choices. I have seen them with the 345 and 304 from IH and have seen the 258 amc. I like how easy parts are to get for the 258 due to the fact they were used in jeeps for many years. I wonder if the Jeep parts can be used in a Scout with no problem (4 barrel carb and intake, headders, starters, alternaters, ect). Please tell me any information you have on any engine choice, ease to work on, avalibilty of parts, mpg, power ect.
