LOL....wow! I wish I could see that.

Funny now it's got me thinking of how cheap those 8100's are going for...$9000-$11,000 with low miles just because no one wants a 7-9mpg gas sucking beast. Would be a fun truck for sure.

His was a 2001 Reg cab 4x4 with 79,000 miles on it. Said it got 8mpg loaded or not. Sold 'er for $9500.00 and bought a 04 PSD that coughed-up it's HPOP the 2nd day he owned it.

Figure all the 8.1L is, is a stroker 454 big-block. Drag racers have spent a lot of money for a lot of years to get that kind of displacement from their BBC's.

Man, my friend had one of those 8.1s. His was prob a 2002? He installed exhaust, CAI and a Hypertech. It was a reg cab 4x4 with an auto. Even after all that work it was a major pig. Id have to see another one that ran good to change my opinion. I bet the D-Max would whoop it pretty bad.

maybe he's just flabergasting... since the "pink slip" isnt actually pink, so ok and get a pink slip of paper. wire doen " you" on it, and win.. see what happens... either way, he didnt specify

The 8.1 is a design of its own, It was used as marine engines before making its way to teh trucks.

Yeah the 502 was a crate motor, I thought that's what the 8.1L Vortec used as a block.

we got a bunch of them 8.1 at work and they haul man, i wouldn't toy with one of them. they pull awsome too. we have them in 2500,3500 singles and two 4500 box vans, and they ride like a dream. and also i got a new chevy gasser 6.0 and don't seem to have a problem gettin over 98 with it. only done it a couple of times gets kinda scary with the utility box i got on it.

I drove a 8.1L with the Alison auto 1 time. It was a crew cab 2500 and I believe it was a 2002 model. I don't really know much about them but I was disapointed with it. I honestly thought it was a dog.
I have a hard time believing a stock duramax couldn't take it.
