Seriously….. Your 8 3/4 will go before a 23 spline.

Unless you are putting out like 800hp+, I wouldn't give the 23 spline a second thought.

Lots of better places to spend $2000.

I know, thing is a got a Dana 60 and was thinking of Turbo my 440 later on and guestimate arround 850 to 900 hp. but i am giving a sh.,.t too much i better get to the river before trying to jump over it!
