Dude those gt40 heads are gonna jack with the S/D already.

 

i have 5:13's in my bronco, i think i was at like 3500 driving like 60-65.......

it has a 408/c6/205/5:13's

they suck for the road......keep your road truck your road truck and worry about the 5:13's for your bogger.......

 

No I know whats involved which is why i haven't done it yet. I just need to get this truck done and running good before I move for school so for now I need to stick with what I have. Any other suggestions keep them coming.

 

No they won't. What messes SD up is a large change in displacement and a cam LSA lower then 114.

 

well is it a mud drag truck or is it a street truck... or is an even mix of the two... decide what the truck will be doing most of the time... and go from there...

 

hey you are aware that ttb's are the greatest axle ford ever came out with right!!!!
Thats why the all new 4wd prius's have a ttb front end too...

 

Its a general purpose truck I guess. I have my 80 f-250 to abuse. This truck will drive on the street but trust me it will be a wheeler. Lift will be about 8 inches with 37 inch pitbull rockers

 

its a mud truck.......but i have to drive it on the street to get it there.....


def. not a street truck

 

Think I should go 4.88 then? The axle I already have has 4.56 but that can change. Teardone will start tomorrow.

 

if your going to run it on the street quite a bit, id stick with the 4:56's

 

yes nick i know about the bronco... and how it abused... i mean used...

As for the truck if its going to be doing an even amount of mud and pavement driving then 4.88 would be where to go. Actually with 37"s you may be alright with the 4.56...
