C2 = 4.10:1 L 6340 Dana
K = 3 spd. A.T. C6

is it LS and strong? Yes
but what about the C6? a C6 is about the strongest Auto Tranny you can get.

Awesome. I didnt really know about a 6340 Dana so I had no idea if it was strong or waht not. Im stroking the engine and its going to base at 450ish so I need to know if they will hold up to some abuse. with the gearing of the C6 what am I looking at for max speed? Will I be able to travel the highway.

The 6340 is the Capacity in pounds the Rear End can support. I do not know what shape the rear end is in but I think you could shell it if you try.
The C6 3rd gear is 1 to 1 so take the engine RPMs and divide by 4.1 and you will have the axle RPMs. Take that answer and the tire diameter and do the math and come up with the max MPH.

Wind resistance verses horsepower determines the Max speed of any vehicle on a level plane.
I do not know what your tire diameter is but 119.4 is a lot for a 4.10.
I do not think the C6 or any Auto Tranny will last long running a 4.10 at 119.4 MPH.
There is also a max rpm for the torque converter and above that it comes apart with authority.
