4:10's ??

I was talking to a performance shop last week about rebuilding my rear end with 4:10's..

the owner more or less told me he would'nt put 4:10's im my car unless I was going to use it solely for racing, he was very opinionated about 3:73's as the highest he would go on a street car....

you guys or gals running 4:10's on the street, how are they?? what rpm's at 70mph?

I have a t-5 in the car...

thx....
