Re: No more Big Blocks....R.I.P.
I have an '04 2500 Extended cab 4x4 with the Allison and 4.10 Posi. It pulls anything I put on it and has never ever let me down. The Duramax is a great engine but I move my truck almost every day out of the shop and would have gummed up a duramax long ago. Unless your non stop towing the 8.1 is the perfect truck. I ordered it new and will keep it forever. JMO. Ed
