8 3/4 What will it take ?

Keep in mid that the max wedges and early 426 hemi's used the 8 3/4 and survived back in the day
dual points were the rave at one time...
But they didn't have the tires, suspension and track prep back then that allows cars to hook as well as they do today!

The ring gear is the weak point. I would suggest a Dana 60 as well.

Yep...."back in the day" pretty much the only way to get a car to hook was to run wide slicks....now-a-days there is several small tire class cars that hook hard....
