The 8.1 is a great engine. I have a 2002 Chevy 2500hd with that motor. I love it. I have a 91 octane tune on it that really wakes it up. The big difference between the suburban and the pick up is the transmission. The heavy duty pickups come with the Allison 5 speed (2001-2005 or the 6 speed 2006-07 classic) transmission and the suburban comes with the 4l90e or 4l80e. The Alison is a much better transmission. The 8.1 came in large motor homes, U-haul trucks and the heavy duty pickups. It isn’t the best on fuel economy but it is very reliable and has tons of torque for a gas motor. Pulling the fuel economy isn’t that far off from a diesel , not as far as you might think anyway. Empty it isn’t much better than loaded. I love mine and I think you will like it in the wrecker. Great choice Matt.

[@scottg391]

A couple of things you should consider on the 8.1 that will make it breath better and not diminish the low end torque. First and foremost is to remove the intake manifold and delete the internal PCV which is the reason the 8.1 uses oil. If you want more top end, cut the bottom of the intake manifold off and clean out the internal restrictions. This will push that long flat torque curve well past 5000 rpm. In stock form they are done at 4400 on a good day. Long tube headers and a tune will get you deep into the 500s for torque at the crank. You won't be disappointed with any of these modifications and this thing should be good for 300k miles +.

Others have mentioned the fuel mileage, but also watch the oil consumption. 1 quart of oil per 100 gallons of fuel oil usage was evidently considered acceptable by GM.

Wow Matt, picking a Big Block over the LS is awesome! This build just really got interesting.

[@joesephrich1924]

I’d love to have a conversation with Matt to understand where he’s coming from with his concepts of gas engines. For comparison, a Cummins 3.9l engine with a few bolt on upgrades but no engine work will reliably push ballpark 500 horse, 900+ ftlb of torque, weighs 100ish pounds less than the 8.1, won’t vapor lock because it’s a diesel, atleast double the fuel economy easily, and will last 4 times as long due to it’s low rpm (hence “million mile diesels”). Those engines are also very happy and well suited for idle work (running hydraulic pumps and generators off pto) which is one of their alternate uses. That being said he seems to have done his research which is why I’d love to hear how he’s come to where he is on his ideas. In the car community I find that there’s often something that the person who doesn’t agree with the decision is overlooking in the process of coming to said decision.

I acquired one of those 8.1 Suburban's from the Ministry of Health in Baghdad in 2003 because my military working dog needed A/C....good times.

I did some math and without at least a 4:1(thinking doubled 205's) transfer case this thing is going to have a lot of wheelspeed even in first gear. Would probably work fine in the sand, but will make rocks and technical stuff a lot more tricky. It does look like you will want an overdrive unless you want that 8.1 humming along on the highway at over 3k 🤣 Just for fun I did the math for a SM465 and a 4:1 transfer case and got just over 1mph per 1k engine rpm. Unfortunately that's a stick with 6.5:1 first and no overdrive. I would love to see you go with a TR4050, it's got good gearing and can handle 600lb of torque in stock form. I'm not too knowledgeable on automatics but you'll need something super beefy or a lot of gear reduction to reduce how much stress it has to take. My guess is you'll get creative with the transfer case and stick with the stock 8.1 transmission Whatever route you take it will be an interesting truck and I can't wait to see it in action Edit: just looked up the first gear ratios on the Allison 1000 (3.10) and the 4L85e (2.85) and hope your transmission is the Allison because it's beefier and at least cracks 3:1 gearing 🤣 you auto guys really don't get anything with deep reduction

you really dont have any idea of what you are talking about.

I like watching your trip from the different points of view based on the different channels, you do have fun. Glad you found the motor, this is going to be cool. Awesome work!

How cool is that to have mountains to look at out of your workshop? Beautiful. And I could see the GuhNats. Nasty little buggers.

I've been the owner of several GM trucks. I once had a used 3/4 ton GMC with the 8.1 engine (496 ci) with Allison tyranny with 40k miles on it and it didn't tow a medium weight 5th wheel camper trailer very well. And It got less than 7 mpg while towing and 10 MPG not towing and miss-fired a lot and didn't preform well. Found out the spark plugs were eroded. Replaced them and that solved the misfire but it still didn't pull too strong. MPG not much better. Found out many owners had same issues. You may have better luck. The one you found has a turbo charger and that may what you need. But you will need a huge gas tank..! I'm now driving a 2016 Chevy 1/2 ton with 5.3 engine and love it. Bought new. There are two leading engines that RVers highly rate for towing Very Heavy trailers, the GM Duramax and the RAM Cummings diesels.
