gm 28 spline power handling??

[mobileaudio25]

Im running a 355 sbc with an 8.5 442 rear end and an eaton posi unit. My motor is about 360 ft tq and 340 hp. im about to install a 3300 custom stall converter and im wondering if my stock 28 spline axles will hold up. Im running all adjustable umi suspension so my car should hook fairly decent. Keep in mind that i will not ever be running slicks though, only drag radials. thanks, kyle

I have an 8.2 Eaton posi with 28 spline and I have 400 hp + with a 5 speed stick and I have no concerns for the rear end and the axles.
