Shouldn't be a problem. All our SRT's have 11's inside them some where just waiting to get out. I'm still with the single cai, stock mani's and stock heat exchanger. Some day I would love to add the stall converter, wavetrac LSD and TCU tune which I really think would get me close to the 11.5 mark. How I pulled a 1.695 60' with drag radials without breaking the stock rear diff, I will never know.
