I'd love to get my hands on an LS juan but the more I looked at my options the better the 6.0 looked.

Shoot, if my motor went south I'd be looking for the phone number for Duraburb real quick. He is doing Duramax/Allison swaps in the tahoes now, talk about all the power you will ever need in a SUV.
