I need to do a major tune-up on the crew cab and was wondering what kind of parts you guys are using for the cap, rotor, plugs, etc. I use this truck for an every other daily driver and a sometimes when necessary tractor hauler. Mostly used for hauling landscaping & building materials if it is put to work any. It is a '91 350 with no known mods other than the obligatory K&N filter. Also, what about the fuel filters? Which to use? Thanks guys.
