I can dig it brother!!!

 

This should be clarified a bit to specify that if you're having any fun at all regularly while in the 400's, it's probably abusive. If you drive it even as hard as you did when it was stock, you will burn up other trans parts, particularly drive clutches. The nice thing about more power with a tighter convertor and more line pressure is that you can drive it even easier than you did when it was stock and accomplish the same thing you used to accomplish while beating on it. But it's worth stressing: it takes a supreme amount of discipline to drive a 2nd gen Dodge that has been turned up at all and not find every week link in the transmission one tow bill at a time.

 

When I had my trans built, I spent just under 6k on it ($5,877.00 to be exact). It has a billet input shaft, triple disk convertor, VB, and high HP internal goodies. The builder indicated that this thing would hold 700 HP easily, all day long. Good for me B/C my mill doesnt make near that kind of HP. Should last me forever-ish.

 

Yeah, power ratings on trannies are very... case sensitive.
