im looking at doing a 6.0 to 6.6 swap i have a 2002 Chevy 2500HD 4x4 with 8.5" of lift and 36" tires and im looking to get some more power out of it. i am wanting to do the swap and i have the time and resources to do it just looking at what all i would have to change to do it. if anyone has done this or any information on it would be some great help thanks.

whippled 8.1l build

for one the 6.0 has a 10.5 rear gears and the duramax/496 have 11.5 rears.. duramax + allison + transfer + rears yea would be cheaper to go to texas and buy one for 10k used

Agreed, even though I was tempted doing this with my truck once i get done playing with big blocks. There is a complete setup for sale in FL listed for sale on here

whippled 8.1l build

yea i would swap my 8.1l to it but from all i have seen guys who go from the 8.1l to the duramax hate it
