How Well with a W/C t5 hold up to my 350?
I just finished building my new rear diff with a new auburn posi, 28 spline moser axles, and new richmond 4.56 gears. I have mickey thompson drag radials which explains why im builing a new rear diff and tranny, i destroyed the old 26 spline rear diff. and non W/C t5. I have a 350 putting out around 490 horse and 460 ft/lbs. Im rebuilding a W/C T5 out of a 1990 formula, how well do you think it will hold up? Im thinking not very well but its all i can afford right now. Thanks for the input.

It will hold up more than a non-WC T5, but less than a T-56..

This is a pretty common topic.Mine lasted until I started running 12's, then it sheared the teeth off third gear.
If you dont race it, and baby it, it'll last a while. But get the coffin ready for it if you race it.
