For what it's worth, I have a buddy that worked at borg warner who used to do clutch durability testing. Now he admits that it was a small sample size, but the Alto Reds were by far the worst clutch he'd ever tested...

I know lots of guys use them, but I kind of wonder if all of the clutches aren't over kill?

We always used just the regular "tan" clutches in our 10 second Nostalgia Super Stocker... NEVER had a problem.

I just put them in the trans for my turbo small block... don't get too caught up in the hype.
