Re: stock driveshaft
The factory 3R u-joints are quite strong if well maintained. I think the 3R is similar in strength to a 1330. Not as good as the 1350 which is preferred for racing but still strong enough for most street cars.

Re: stock driveshaft
If you plan on running that quick, invest in a better driveshaft anyway. You'll probably need a custom length driveshaft after replacing the entire driveline.
3" x .083" wall steel shaft with 1350 u-joints and yokes.
