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.

 

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

 

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

 

Yeah if i built one it would be far from stock
