okay well i have a 93 f150 300 stright 6 that i had giving to me. its in good shape but has alot of miles 180000 i dont know much about these truck im a 5,0 guy i own a 5.0 mustang with 400 hp i herd pretty good things about 4.9 but willit make a decent mud truck it has 33s on it but i wanna lift it and put bigger not to much but a lil biggerlike 35s

 

4" lift is in order for you, and yes the 4.9 is a great engine, lots of low-end torque. Won't make stupid power like the 302, but for a 4x4 truck I like it better. Methinks you'll do just fine with it. By the way, with that 400hp 302 you're getting close to the physical strength limit of the block, just a heads-up in case you decide to go bigger there.

 

im just carious like i wanna have a good mud truck and somthing that will climb decent hills like the truck was givin to me so im happy either way but allmy friends got big trucks and go muddin on the weekends and i want somtthin that will do okay in the mud and yea thanks for the heads up im not going anybigger for a while

 

personally if it's just a mud truck i would swap the motor out for a carbed 460 with some decent heads

a 300 won't make enough power to spin really big tires (not sure on 35s) and those motors dont rev at all

what do you have done to get 400hp out of a 5.0? i assume at least cam and heads and forced induction? i'm curious because i only have like between 300-350hp without nitrous but i'm spraying a 125 shot into mine ontop of that

 

Your 4.9 should make a pretty good mud truck but i think you should consider a gear change if you put anything bigger than 33's on it. You certainly wont have the meanest truck around but it'll stand it's ground.

 

Gear change should be in order for sure, IIRC them Bronco guys like the 4.56 gears with the 35" and 36" tires - won't be a fast truck, but will do well in mudding, and won't brake stuff. Will definitely need the D50 stub shaft in the D44 front axle tho, and of course manual hubs in the front wheels if it still has the factory automatic ones.

 

since you have a 300 six go with 4.56s for 35s or 36s but if you had a motor that liked to rev like mine 33s and 4.56s are in order i'm at 3k at 60 with out overdrive and like 2k at 60 in overdrive so it works well because my powerband starts at around 2800-3k so for gas mileage put it in overdrive and for passing drop it out of overdrive and your up to 6k before you know it

 

Bigger isn't always better. Downsize tires to something tal and narrow (like 32x10's) and re-gear to 4.56. Your 300 will hang with the best of them.

A 300 is an excellent motor but once you start putting huge tires on it you start bogging it down. A 300 will hang with the V8's in the mud if you keep it smart.

Besides, narrow tires will cut through mud much easier. Wide tires will hurt you. I run 31x10.50's and I like'em for my needs. I don't do serious mudding though. In the mud I've been in though these tires just propel you forward.

 

I will be regearing really soon and i was going to go with 456s with my 302 and 35's is 488's going to be a better choice? I may end up with 38s at some point. and i look foward to finding a 460 someday..

what is the stub shaft? The front driveshaft ? Assuming the dana 50 shaft is alot stronger?

 

For now go with the 4.56 gears, I think you will not like how high the 300 will revv with the 4.88s and 35s. When you get the 460, then put the 38s and regear to 4.88 if you feel you need it.

A stub shaft is the short shaft that exits on the passenger-side of the differential in the left traction beam of the D44 axle, it has the middle U-joint attached to it - go under your truck and you'll see what I'm talking about. The intermediate shaft that runs inside the right traction beam and connects the stub shaft off the diff with the right wheel hub is pretty strong, but that short stub shaft and particularly the U-joint that is part of it is a known weak point in the TTB D44 - the D50 stub shaft has considerably larger (and stronger) U-joint, which eliminates the potential issue with it when running large tires. On the left side there's no stub shaft, as the differential is part of the left traction beam and moves with it so a straight shaft works just fine there. In other words - there are 3 U-joints in your front axle, unlike a solid D44 from the 70's that only has two, the middle U-joint where the two traction beams cross is the weak one that you upgrade with the D50 stub shaft.

 

Im sorry i meant to say i had a 302. Knwing i need to get revs to power this thing 488s would be a better choice for me correct?

 

no offense to 6cyll....but a narrow tire woild actualy be conterproductive in mud...because a wider tire helps you stay on top and it gives you more surface area for traction. why do you think serious mudders run WIDE tires like up to 14 inches.

also to the original poster..... i would say that if you go with the 35 in a bogger and 4.56s and maybe just do a good tune up and advance you timing youll do good. just remember that almost all the 300s power is under 3000rpm so just dont wind it out and.......have fun thats the most important thing

 

Oh, you said it right, I was just still drinking my coffee, so my attention was elsewhere With the 302 if you're regearing anyways the yah, instaling for the 4.88s from the get-go would probably be a good idea. Have you done any engine upgrades? Bumping the initial timing a bit is the easiest thing to do, it only takes a few minutes and tis free if you have a timing light (or a buddy to borrow one from).

 

Yeah timing is bumped, Has longtube headers, and dual exhaust. 5 speed tranny jus twant to gear it up. and look at more cubes down the road.

 

Whatever you say man.
