Decision on best traction for 9\", trac-lok, or Auburn is best???

I need to decide what to put in my 9" rear with 389 gears, a mild 351W with Edelbrock performer cam, intake, and carb in
my 70 fastback Mustang with a fresh motor and a fresh
C-4.
I need to decide if the Auburn is worth an extra $190 over a Ford Trac-Lok to take me up to the $1000. mark on a center section.

I plan bigger heads, performer RPM upgrade setup and nitrous 100HP fogger soon, as well as a 2500 stall TC maybe end of summer.

Ideas??
Thanks!
Todd

I would opt for the Detroit soft locker. It will last longer.

I too vote for the locker. I have had two buddies blow their auburns with "mild" street motors.
Just my 2-cents

locker & aftermarket axles if going to the track much. lockers can be harder on axles than a spool.

Locker!

How can anyone expect a clutch pack that is 4" in diameter to lock two 28" wheels together for long?

Locker!

Locker!
