Not very likely with your setup and an automatic trans. The 9" and Dana 60 are heavier, eat more power, need custom sway bars, and usually require you to use non-GM brakes.

Unless you've got a solid 9 second car cutting sub 1.4x 60ft times, go with a 12 bolt.

Not a "Dana 60"!!

Check out the gears section on LS1tech.com and read all about the 12 bolt vs. the 9" vs. the 60....I ended up going with a Moser 9"....I didn't need a custom sway bar and my Baer brakes work perfectly....

Learn how to drive and you wouldn't be breaking rears.
