They are obsolete. Drive a Duramax or strong LS engine and you will see why nobody needs the old big blocks anymore. [/ QUOTE ] I drive a new 6.0 powered 3/4 ton Chevy every day at my job, and I have to say it's stronger than any older 454 truck I've ever been around.

[/ QUOTE ] LOL...true to a point, but the Dmax is terribly complex/expensive, and the LS engine in the HD series won't pull with the big block...my opinion, the 8.1L was *the best* bang for the buck for a no-nonsense HD/towing application. No, you won't have the unloaded fuel mileage of a Dmax (loaded they're nearly identical), but the 496 is 10x easier to maintain or diagnose than it's diesel counterpart. And, last I knew, the 8.1L carried the highest *legal* GVW in the 3500 chassis (before they axed the engine option)...  Not to mention the added initial cost, added maintenance costs, etc...don't get me wrong, we own 2 Dmax trucks and love them, but we also own 2 8.1L trucks...and I hated seeing the 8.1L option go.

Re: No more Big Blocks....R.I.P.
 I love my 8.1 and the 6.0 doesn't compare when pulling trailers. I can't offer an opinion on a 6.2 with the variable cam phasing. I'm sorry to see the 8.1 go, especially with how the newer diesel are less mod friendly and super complicated.

Anyway, every one of the 6.0 guys say it's the same gas hog the 8.1L is, minus the extra grunt...and you're stuck with either the 5-speed manual or the 4L80/85e, versus the 6-speed or Allison if you go 8.1L.

Do you happen to know what the last model year was that Chevy offered the 8.1 gas motor? And I have heard the same thing on the mileage, around 10 when towing with both  Your working the 6.0 harder with less tranny. JMO

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
