Howdy there,

I am about to finish college and i am building my dream truck for use as a daily driver and to haul me and a trailer where the Army is going to take me in the next few years.I have no problem driving 55-60-65 all day long. I love taking my time while driving. I have a few questions about the final drive ratios and if they will be useful for my truck.

Here is a link to my build: https://www.ford-trucks.com/forums/1...storation.html

Engine = Use the block as the base for a the stoker motor. Bore .030 over and stroke it to 4.250 for a total of 445 cubes with the kit from the guys at survival motor sports. Have the D2TE-AA valves replaced with CJ sized valves. 2.09 intakes and 1.65 exhaust. Then port the exhaust bowls. Mainly in the roof to flow a bit more air. A cam that the stroke kit suggests. A High volume oil pump and Milodon stock replacement FE pan, along with the oiling modifications that are common to increase oil flow to the bearing mains. Edelbrock Performer Intake, Edelbrock Performer 750 Carb, Dynomax Ceramic coated headers, K&N air filter, dual 3 inc h exhaust exiting at a 45 in front of the rear wheels. The engine will put out 450hp and 550ft lbs.

Transmission = Clark 285v33 that i pulled out of an 78 F800 in a local bone yard. I have the Clutch and fork, Flywheel, Starter, and the bell housing off of the FT motor it was attached to. I believe has the following ratios. 1st-6.99, 2nd -4.09, 3rd -2.24, 4th -1.47 and fifth is direct.

Transfer Case = BW1345 with about 160,000 miles on it.

GearVendor Overdrive = I have a chance to pick one up cheaply off a 1988 F150 with a C6 trans , it is a GKN J type with a Gearvendor adapter that replaces the rear half of the transfer case. It is the 22% RPM drop model. Has 100,000 miles on it.

Rear End = Sterling 10.25 and a Dana 60 front from a 94 F350 with 4.10 gears. I plan on putting Detroit lockers in both.

Tires = 35 or 37" BFGoodrich All-Terrain T/A KO, or comparable tires.


Questions that I have...

Will i be over driving my engine? Will it be worth it to capitalize on the power and torque in an effort to better the MPG?

Good tire choice? I don't necessarily want huge fatty tires just tall ones for a good raised look and good cruising.

Would it be worth it to install 3.54 ring and pinion sets instead of the 4.10? or would that be too much?

Is it possible to install a lower rear ratio ring and pinion? I believe the problem is with the Dana 60 up front... anything aftermarket?

Thanks in advance, i have been reading through this site for years now collecting information for my build, and you guys have always be very helpful on both the opinion and the technical sides of the discussion.

 

Definitely answered all my questions i asked here through research of my own... Here is the link again if anyone wants to know... https://www.ford-trucks.com/forums/1...storation.html
