I have had a 1990 F150 5.0 XLT Lariat for around 10 yrs. Its a regular cab long bed 4x4. Have done most popular mods to it, 3G alternator, PMGR starter, air pump eliminate, FlowMaster y-pipe with single cat in place of dual cat factory y-pipe. Recently pulled engine, bored .40 over, put Hypereutectic pistons in, and converted to 94-96 model roller cam, so yes now has HO firing order. All upgrades were to make truck more dependable and add a bit of push to it while keeping it basically stock, but better! It's black & grey 2-tone and thinking about getting it painted, the grey is popping off in some places.
