Get the most out of 4.2
it replaces your crankshaft pulley and possibly harmonic balancer(99 and newer) with a pulley of a different size. this makes your accesories(powersteering,ac,etc) run slower and therefore have less of a load on your engine, thus more power. raptors got a good start for you. specifics-magnaflow or flowtech warlock muffler(flowmaster looses torque), mac cai, vmp tuning(progamer,not a chip) e-fans are good. headers dont go alot on our engines unless youve done all the other bolt on stuff. one of the biggest differences will be new lower gears. however this can hurt your mpg's if you do alot of highway driving. alot of guys on other sites will put a 75hp shot of juice on too for quick semi cheap power. itll never be a v8(power and sound
) unless you turbo it(for power) but you can make them faster

ok well ive got the magna flow on its way and a edge programmer not too far behind! then ill be putting on a k&n cold air intake! 4.56 gears will be working their way in as well! and madmax thanks for the pics of the toolbox i just did mine and it came out great! ill be putting pics up soon!
no problem, glad i could help, definately put up some pics when you can. 4.56 seems a little steep for anything under like 35s or 500+hp drag trucks. it also seems like youve done your hw and have some good stuff coming.id definately look into the udp's and efans as the next step. k+n's are great but you can get basicaly the same thing for around $160 in the mac intake

I recommend 4.10 if you want an "all around" gear.
I was reading around, and by having your engine run in the 2k range all the time is actually good.
Heck my V8 Dakota runs 2200 rpms on the highway at 65.
My F150 runs around 2100 rpms on the highway at 65.
