In the near future i will be getting a rear-end most likely a Ford 9inch. And i was wondering whether getting 430 gears will be to much, or get the 4.11s? I am really looking into staying all motor going heads and cam for now then jumping into a different motor later on. But i was wondering if you guys think the 430's will be to much for the street. Any opinions would be great Thanks

If you have a 6 speed then not even a 4.56 would be too much for the street. I think that 4.30 is about perfect for a 6 speed car if you want to race it. A friend of mine went from a 4.10 to a 4.30 and loves it. He said that the 4.30 got rid of the slight bog that was still there with the 4.10 after launch.

I have them on a stock SS. 1st gear is useless on street tires
If you mod the motor you will run out of rpm in the 1/4 unless you bump up the rev limiter or go to taller tires. I run out of rev in the quarter now, about 100 yards from the end, trapping 109 with a 6400 rpm rev limit and BFG DR's.
BTW, dropped .4 in the quarter - traction limited to 2500 rpm launches

4.33's you WILL need to run a 27" tall tire if you plan on running past ~118mph unless you have an ungodly rev limiter.
I believe 4.10's and 26" top out at 118 with a 6700rpm limiter.

would 130mph be feasible with 4.56's running 28x10.5W tires and holding it to 7300rpm? Im thinking that I might need to step down to 4.30's if I am looking for that trap speed.
