Description
10/23/12 -- The truck has been pulled off the road for a long list of repairs for awhile. Will be trying new improvements in the future. It is no longer a daily driver, and will be for hauling and bad winter driving only.


Old News:
4x4 3/4 ton capacity truck with factory lift. Extended cab with long box. It has over 140,000 miles and a lot of the driveline is wearing out, it needs a good rebuild and alignment. The 351W has run on Mobile1 since I bought it with 76,000 miles and is still running strong.

The closest match I could find on the EPA site is a 1996 F150 4WD with the 351w. Although I tend to believe rated mpg would be lower than an F150 based on extra weight, and height of the lift.
Modifications
Electric fans, heated rear fuel tank and fuel lines, removed engine coolant lines to throttle plate housing, disabled smog pump valve, K&N filter. Also tried Acetone mixtures with no result. I have an hour meter installed that logs engine running time, which I use to calculate average MPH.

August 08
Removed bug deflector and window vent shade .. things. Installed new Dynomax cat-back exhaust system. Installed air dam, and removed rear mudflaps.

September 08
Installed hidden coroplast grill block. Finally added thermostatic control to electric fans instead of a toggle switch. The temp range seems a little low, the fan kicks in early IMO.

November 08
Installed vacuum gauge. New rear brakes, rear axle hub seals, topped off axle with 1.5 quarts of mobil1. New Bridgestone Dueler A/T Revo tires are installed. They are the stock E rated 235/85R16's, my old ones were D rated 285/75R16's.

May -June 09
Refurbished the air dam with stainless steel bolts(Galvanized and aluminum don't mix with road salt), covered underside of air dam framing with plastic. Also added connection points for a future detachable belly pan for under the front axle. Installed the license plate over the small vent in the middle of the front bumper. Covered up center door in air dam semi-permanently. Removed my old fuel heating system after finding a rust hole in my rear tank. It now seems heating fuel was harming more than it was helping. I ended up opening up more of my grill block for the summer.
Planned Modifications
New idea for WAI- use part of the radiator with some shielding, ducted into a stock air filter box. This should help some of my electric fan run time. I think this would help keep from over heating during lead foot conditions. My shielding idea would circulate the air in and out of the radiator core multiple times before it reaches the air filter, giving it more chance to heat up to higher temps. The tricky part will be to not interfere with the AC coil.

Stainless shorty headers, under body and axle smoothing, some sort of aero cap, Edelbrock performer intake for trucks, Detriot True Trac locker.
