Thanks for the advice guys.
My 4.7's are great, plus I have a R151F with a pretty low 1st gear. I use 2nd and 3rd a lot, and 1st when I really need to creep.
Blackdiamond, now ya got me wondering if I will need to rotate my diffs. My front axle housing is still bare at the moment while I collect parts. Am I going to have to rotate my knuckles to keep streetable caster? I'm on the freeway a lot @75-80mph.
I'd like to get this right the first time. Not find out my truck isn't safe and have to pull it apart again.
I was leaning more towards Longs and if I get my front axle positioned right maybe a HP won't be necessary.
Keep the advice comming. I need it and appreciate it. Thanks.
