Can I replace a 4.6 with a 5.4?
HI NGM, You look like a good resource....I own a 98 2wd f150 with 220000 miles and need to rebuild the engine. This thing looks like a pain! Unlike the days when I used to put an engine on a stand and rebuild it in 2 days. I would like to come oout of this with about 500 hp. Would you say it's best to rebuild at closest to OEM specs and concentrate on nitrous,chipsets or attempt to start and the beginning and build a monster? Can you even do much with this block/head configuration?
