I just sold a 89 F150 4x4 xcab with 5.0 and 5 speed.
My new ride is a crew cab f150 with 5.8, 4x4, and E4OD auto.
Man what a gas hog.
It is heavier, and auto...I understand, but I was shocked!
Few questions, all specific.
1)It has 18.2 gal tank in rear...that is it...it goes dry fast.
Can I add a tank? I have no 2nd door...maybe find a short bed with 2 tanks to swap on? ANyone know if I can add the front tank? It is a custom truck so I understand if that makes a difference.
2)Are there are EEC upgrades or tunes or tuners that are worth the money? If god forsaken i can't get any more MPG, then I want more performance...plus I don;t like how the trans "thinks."
3)Lift kit, what is the best 2" suspension kit? No body lifts please.
i dont know what ur mileage is but im pretty sure once you do the 6 liter tune up it probly wont get much better. i get about 15 with mine and thats the best it will ever be. if u get more than that out of a 351 auto then u have magic.....
i think the 2" leveling kit is the best idea. daystar makes one and im sure others do.
i dont beleive that there are any tunes for it, but i could be wrong.
do a new exhaust and help it breathe more, and for god sakes stay away from the hot air intakes... these motors hate them. and almost everyone on here hatew them
usually the 250 and 350 get the 8 mpg's... the half tons should get 12-15 i would think. he should have 3.55's in it and with the 235's stock should have no problem getting 15 after the tune up... IMHO of course
If the air filter is open to the engine bay area that is a HOT air intake.. despite what the advertising says. The stock intake setup is a true cold air intake.. meaning it draws air from outside the engine bay which in general should be cooler than what is near the motor.
What size tires are on the truck and what milage are you getting now?
