Which Dana 60 Differential and axles ?

[DonnieLawson]

Getting ready to have my Dana 60 narrowed , I have a 4.10 track-loc in it now with 30 spline axles that I will toss and have new axles made .
My question is ...... should I throw even more money into it and get another Differential , such as a TrueTrac or a Detroit Locker ?
Are the 30 spline axles strong enough with my stock track-loc ?

My car is an all steel 68 Barracuda fastback , 505 cubed RB , 727 tranny .
I haven't picked out my converter yet .
Rough guess is 600-630 HP with the CNC'ed stealth heads .
99% street driven with a few passes at the track a year , and maybe some on the street also
I will have drag radials on the car as soon as I get it mini-tubbed . Which is being done now .
Should I stay with 30 spline ? Or jump to 35 spline which then I have to get another differential .
And which differential if I do change ?
I did get the wilwood rear disc brakes for the car .
I was hoping the factory dana stuff would hold up to my heavy right foot .

I would put a call in to Dr Diff , he is the master of those and will steer you in the right direction . Google him .

I would get a powerlock or a Locker with 35 spline axles.

By all means a Power Lok with 35 splines. I'm interested in your old 30 spline posi, What do you want for it? Email me at [email protected]

I should be stopping by my friends house Sunday after work . I'll take some pics and try to get some numbers off it for you .
The Dana is with the car , and the car is being mini tubbed now .
