I need help with part #'s and specs for my 1985 4x4 F150 I6. I purchased a used engine that I want to have rebuilt and replace the one in my truck. I would like to have this done right so I'm asking what would be the heaviest/best type of bearings,pistons, ect, to use in the rebuild. I also would like to switch this truck to non-computer. The engine wiring harness is already bad along with the carb and most if not all vacume lines. I bought the truck used (4 owners) and it really needs help. If at all possible I would like to switch the carb to a 2barrel in the process. I am not concerned about emmissions just want to have the best running truck possible after all done. Any help would be greatly appreciated. Thanks
