Which differential and gear ratio?
I want to get as much power to the ground as possible but dont want anything un-streetable like a locker. I'm thinking either 4.10 or even 4.30 ring and pinion and either Detroit TruTrac or Auburn Pro Series differentials. I will be using this setup strictly for street use. I want the best setup to lay some rubber and just plain rip. The 3.73 with open differential is pathetic. I WANNA LAY SOME RUBBER! any suggestions in brand/model/ratio between the gears and differential??? i have the 31 spline

well, i had an 89' tbird supercoupe 5spd with mods and and i drove it like i stole it. if anyone knows about supercoupes, they surely know what kind of rubber these cars can lay. so i went from this to my 05' 4.6 with a 3.73 LSD. im almost depressed everytime i go to punch it from a stop. i don't mind getting new tires here and there, but i do mind being above 2250rpms at 70mph. randy's ring and pinion says my truck with 4.30 going 70mph will turn 2219rpm. with 4.10 it's 2116rpm. *(with the 3.73 it turns about 1925 rpm)* My question is: switching from 3.73 to 4.10 OR 4.30 how much gas mileage might i see to lose at freeway cruising speed(70mph)? Also, how much more powerful will m truck feel switching from 3.73 to either 4.10 OR 4.30? AND WHICH DIFFERENTIAL DO YOU GUYS RECOMMEND!!!? lol

I'd say go with the 4.10's made by Ford Racing, and a True-Trac limited slip. It's going to be expensive but you'll like it. As for mileage loss, it should be hardly noticeable, .5-1 MPG loss if anything. I wouldn't go any higher than 4.10's just because it's a 2WD with street tires.
PS Post some pics up of your truck man!
