[QUOTE=Chris Buresch;327863]Yes it's very possible. Guy here in Florida does it to Suburban, Tahoe and Silverado. You have to change transmission, front and rear axles and lift truck minimum of 3" for clearance. Fuel tank too and other electrical and computer changes also. Going to replace my 5,3 with a 2011 6.6 duramax.

Where is the Guy in FL located, I would like to get more details for this swap & recommendations. Thanks.

 

what about springs...how are you gonna fit torsion bars into coils? the rear spring shackles won't fit.
and after all that, your still on a 1500 frame so your tow rating is less than original due to the weight of the swapped engine and trans

$10g for a motor and then add all the other stuff?
