I own a shop, and a drag car & truck. In my truck I run a 3.73:1 ratio gear with an eaton limited slip posi-unit. I also run a 700R-4 transmission with a stall converter. My engine puts out about 430 horses give or take, and I drive it on the street. If I were going to strictly just use it for drag racing, then I would want to go with a much lower gear, and a better transmission. I have a beefed up transmission that has had everything done to it, and it will whiplash you when it shifts gears. Its got a kevlar band, racing clutches, more added to forward pack, racing planet gear, stronger sun gear, a Corvette governor, and a TCI shift kit. It has a 3,000 stall converter, and has been bullit proof so far. I run it all the time on the street, as well as the strip. Your gear is going to depend on the transmission you plan on running in it. If you are going to run the 1/4 or 1/8 mile also comes into play. If you plan on street use, don't go any lower than a 4.11:1 ratio or you will be running the engine to death at 55 mph. I run a 3.73:1 because I'm using the 700 which has a much lower 1st gear. It shifts to second almost as soon as it carries the front wheels about the length of the truck. It sits down real easy, and goes in a straight line. What more could I ask for?
Glad to help out, Good Luck!!!

It depends if this truck will be a combination street driver or a drag race only truck. For strictly competition drag racing you'd need a 4:56 rear end with a high 3,000 rpm stall speed torque converter if it's an automatic. If you multi-drive in the street and occasionally drag race it it's safe to say that you'd enjoy the jolt of 3:90 gears with a 1,500 stall speed converter.
Peal as much weight off the truck as possible. Fabricate lighter bumper brackets. Remove the hood hinges and fabricate a tab with a bolt hole and prop the hood open with a steel rod from an S-10. Constantly be thinking about weight.

Call up summitt or jegs and let them know what you want to do and they can tell you what gears you need. Are you going to be trailering this to a track? Or are yo ugoign to be driving it to the track? If you get to high of gear you wont be driving it to the track unless you bring extra fuel for the ride there.

It depends on what type of racing you want to do. If you're drag racing you want a lower gear ratio, if you're wanting higher speed for long distance you need a higher ratio..

are you talking road course racing, straight line, track?
depends.
for straight line, i'd go with a 4.10 posi, for road course and track, i'd go with a 3.55, so you won't sacrifice your top speed too badly.

I love the 373's in my truck but if your on track only you might go bigger.
