That would be correct sir. So your saying it would be fine then?
If I'm going to rebuild one, I'm definitely going to use the "performance" kit with kolene steels and red eagle clutches.

All I can tell you for sure is that I have been running mine for almost 10 months with some high gears in the rear and a stage 2 shift kit and have done some real hard second gear full throttle shifts and burnouts as long as half a block.
Seems fine. :D
