LB7: 411 gears

[WolfLMM]

Guys what do you think about 411's and drag racing?

I know they will help coming out of the hole, but could hurt me on the big end of the track. This is on a 600hp exsb 4X4.

Whats the verdict on gears? Are the 373's what I should stick with? Would 411's make this thing meaner on the street?

Thanks,

Wolf

4:11's would help greatly on the track. Just don't get on the highway and think your gonna do 70mph and get 20MPG.

oh, what size tire?

Generaly with any turbo motor you do not want low gears, they don't put much load on the motor when launching and load is what helps spool turbos. This is one of the reasons second gear launches work better for some.

So I should stick with the 373s then?

I personaly would. I look at it like a Buick. In stock form 3.73s help a little, but once you do a little work to the motor you end up going right back to 3.42s because the motor will rev faster than the turbo can. I would stick with 3.73s unless you have some real big tires. Even then I would just gear it to get back to the stock final ratio.

I would stick with the 3.73, or even go 3.42 if you plan on running shorter, higher traction tires.

I put in 3:42's and like them alot.

What size tires are you running with your 3.42's? How did it affect your 60' times?

31.5 inch tall proxes. 60 fts. didn't change, but my 60's have never been that great. 1.70-1.75.

I was thinking that if you went with a larger tire it would bring the ration back closer to stock. I only have experience with larger tires and not very much with drag racing these tucks.

if you go to 4;11s the grip will be better.
