i just put my 4.10s in with a cc and 31.5 in tires. while it is a big improvement coming from 3.23's i prolly could have gone 4.30s. so for u with 33's i think 4.56 would be nice. you can still add the heads later and have even more power too. what about intake mani to go with the heads?

hi I am having the same debaite hear as well my 2500 avy is a heavy truck but with the money I put into the 8.1 it seems slow I talked to yank converters and they told me with the towing that I do changing my stall was out of the question they recomended that I just put in lower gears. factory I have 3.73. I am also running 285-70R17 BFG
KM2s I am trying to decide weither to do 4.10 or 4.56. right now I am leaning toward the 4.56s. my truck has a lot of low end grunt but I still like to have a little fun hear and there. I raced a couple in a bmw 5 series last week and got in front of him and he didn't pass me back up till I was almost through 2nd gear. I SAY GO WITH 4.56 gears
