You've said it previously - the Morrvair soaks it all up, AC runs cold, never overheats. Don't touch the engine! More power = more cooling requirements, busted transmissions, transfer cases or axles. It works beautifully as it is!
If power has never been an issue, don't mess with it. You're not gaining anything useful, and open yourself up to breaking parts that have this far been reliable.
You don't mess with perfection; upgrade the Morrvair's engine when it ceases to run, not before. Also, nice to see Jordan FINALLY get a proper introduction!

Razors are great, for what they're designed for. They aren't made for flying. We only see the small percentage of them that are broken because the working ones don't need recovery. Also there's a lot of tourists renting them who have no off road experience

But get the motor built and bagged before you need it. Upgrade the valve train so when you're winding out a gear you have some more rpm to play with. Just plan on a freshen up on the transmission when swapping it.
Yeah jumping up on the slippery wet metal and sliding back off probably just scared her a bit. It's a fun laugh once you realize she's fine (as seen when she jumps back up afterwards.)
I think the decision to upgrade the engine in the Morrvair is totally your call. The motor you have seems to be working just fine. The Morrvair does the work without struggling so do whatever you want. I’m satisfied.
It's a testament to "truck cams" in the purest form. Bigger ports/heads/compression and a cam would just make different reliability issues, but if you do it right, which LT would, it could light off a new level. Needs vs wants 😈
Practically speaking - if it a'int broke, don't fix it. I've never seen the Morrvair bog down so you don't "need" more HP/torque. Now, if you just want to put a bigger engine in for fun - go for it.
A low buck 408 stroker would put them in the 525hp range on a mild 91 octane. Moderately sized cam too. Would operate in the same rpm range but would make 30% more power. They would have to check the radiator flow to make sure they can cool that but that’s an easy solution.
10 minutes ago a crack off-road recovery unit was sent to collect a bunch of Corvair parts that they don’t really need. These men promptly escaped from the MOOR compound to collect the parts. Today, still wanting more parts, they survive as Corvair hunters of fortune. In the meantime, if you have an off-road problem, if no one else can help, and if you can find them, maybe you can hire the D-Team.

Morrvair just works! Don't mess up a good thing just because you can. Only reason to change the engine (and possibly upset the vehicle balance) is if the current engine is giving you trouble. Peanut is one GOOD DOG!
I agree. If they have never had a situation that the Morrvair failed to get the job done due to power, then adding additional power is just likely to increase breakage or wear and tear.
I seem to remember them taking the banana or wrecker on jobs because the morrvair didn't have the optimal power to weight ratio. I also remember them saying it's underpowered, but was built with what they had. Should never shy away from improving a work rig because there might end up being another weak point. They are improving and removing the weak points as they go. It's all part of going off road as factory vehicles and parts are designed to be used mostly on road under normal circumstances. The way these rigs are used is anything but normal. Look at all the improvements needed for the banana and how it's improved. This became even more evident when they built deja blue to how the banana should have been built from the beginning instead of countless variations and improved designs. I wouldn't say Matt is done with any of his recovery rigs. He's just in field testing phase to work out any issues and improve upon previous designs. Custom rigs are never really finished anyway.
I wouldn't change your MORRVAIR until it needs to be replaced, you have so many irons in the fire already. Don't replace that motor unnecessarily. If you are supposed to replace it something will come along that seems inspired, that will be time, hold off for now .
Who doesn't like more power and with what he does with them, more power is useful. He has the money to do this, he makes his money on youtube filming content like this and he gets to do this with his kids who are learning mechanic and fabrication skills everyday. Why not?

You know GM uses the same radiators and transmissions on both the 5.3 and 6.0, right? Considering how over built the morrvair is, there won't be any problems swapping it over, with its 205 tcase and 3/4 ton running gear.
@@thespacedpirateThis is the best comment ever Why or how are people only seeing negative things about a new engine like what. It really makes no sense to me why so many people want Matt to keep a 5.3l that has so many miles. When a new engine that will bolt right in and give more to the Morrvair its insane.

There was a rather nice Morrvair wipe cut at one point as well. Matt needs to look after young Colby, because he adds significantly to to this channel.
I have an 06' Silverado 2500 2wD 6.0L with 320,000mi AT still going strong and tight. We use it as a company workhorse pulling trash and tool trailers, hauling building materials and running errands. We've owned it since 90,000mi back in 2014. Maintained regularly scheduled maintenance, tuneups and all the standard attached running gears, bells and whistles. It is an impressive engine. We also own two other Silverado 2500's with the 6.0L 4wd AT 06' and 05'. Both engines going strong and tight with regular maintenance and tuneups scheduled and diligently followed.
I don’t drive the Morrvair, obviously, but from what I’ve seen it has lots of go and has never bogged down. It looks good to me as it. A bigger engine may be a nice to have thing, not a need to have thing.
So many times, I see people just "add" or "install" a blower and don't fully understand that going Forced Air requires a lot of changes to the engine, like the correct Blower Cam, bigger injectors, boost-a-pump or a bigger fuel hat, optimum compression, Etc. Then there are those who only plan on "a little boost", maybe 10lbs and fail to recognize that the demand a blower puts on an engine and only running a little boost is actually losing power or if anything just a wash. If you're going with a supercharger you need to understand the advantages and disadvantages of Centrifugal, vs Roots, vs Twin-Screw. And of course, the relatively new Electric blowers that take some real talent to correctly tune.
Fuel sump/surge tank and let er eat. You're wrong about parasitic power. Get a magna 4303 and pwm controller on fuel PSI if you're out of fuel... The LSA with the blue/red ECU is instant 4-8 lbs boost @ idle and has a sane bypass to not overheat intake charge. Need an intercooler, but it's sane up to ~8lbs boost on 6.2 liters.
I don't recall seeing many videos where I thought "man, the Morrvair could use a little more grunt." The way you've got that truck geared seems to work pretty well with the power the 5.3's giving you. A healthy LQ4 would be nice, but I don't think you need to consider that until the 5.3 starts giving you grief that you can't keep up with.
Regarding the morrvair engine, if it ain't broke, don't fix it. Bigger engines, means bigger power. Which means the possibility of more expensive parts breaking.
Wow, nice new video view... like the new wide angle view of this video. New camera, new settings. What ever this is I like it. Easy on the old eyes! Thanks and kudos to the camera/video people!!! 🎥
For the Morrvair, have him build you a 5.3 with a little bit of cam and some mild boost. That’ll be plenty and won’t be too much of a maintenance headache. One of the features that keeps your fleet reliable is not having too much fancy and finicky stuff.
He might be one of us weirdos that just builds up leathery dark skin on his head..... I only wear hats out of desperation, never remember to lube up the skull with sun block. I usually end up with a sunburn first part of the year, but after it's burnt once, I do alright. 6 hrs on the jet ski the other day added some color.... companion that was with me had sunblock and ended up lobstered. She called me a mutant.
Brother hailing from Arizona, monsoon season can be deadly -105F + 40% let's gooooo. These folks are cut from a different cloth. Rocky mountain strong is a different level.
The issue with most of the LS family of engines for rock crawling is the short 3.622" stroke most of them use. Only the LS7 uses a 4.00" stroke. If you need a bit more power and fuel economy is a consideration, I would stroke the 5.3. With a 4.00 stroke, you would increase displacement from 5.3 to 5.8, and a 4.125" stroke would be a 6.06 liter. Put a longer stroke in it for the increased lower rpm torque and make sure you are cammed, convertered and geared to match the RPM you want to run. My suggestion is build it for low RPM torque, and stroke is the way to go. If you turbo, go small turbo, low boost, so it's useable in the low RPM ranges. Don't compromise your compression ratio for the sake of a high boost/RPM power numbers. Regardless of the way you go, you must match your components to get the best performance for your spend. When you get the combo right, you will not have to work the engine as hard, it will run cooler, and get better fuel economy.
I have a 2015 Silverado with a 5.3 and at 210,000 miles replaced with new engine. A lifter ate up cam lobe other than the 4 to 8 cylinder bull that I stopped with a chip in the diagnostic port plled my 30 ft trailer just fine. Now have new brakes, struts,shocks,tires (ko 2s, it's a k1500), radiator, it's my last Chev pickup of my life. new truck. At 80 y/o a new truck would just be a rental. My 2008 f350 has 222,270 on the ticker, 6.4 powerstroke, front-end rebuilt, new tires, etc. Great towing, outfitted for overlanding, self recovery, and slight pinstripping. Over time, invested in upkeep, has paid off. I'll be by to visit you fellas this fall. See you then. Maybe this time I'll finally meet Matt, then have another old man story swap with Ed.
I like a big cams, big compression, tight heads, lots of carb. Almost blew heads off a 283 cu in, used 327/ 375 hp cam, stock heads, pushed studs out of heads. Found some 327/ 300 double hump heads. The studs were pinned. Made lots of power for a mostly stock motor.
On the Morrvair, it works. Has the power ever been a letdown? No point in having more power than you can put to the ground. I'd be temped to change the engine for it's "younger sister" just to keep it reliable.
Keep it reliable. You've got it to the point that its got a drivetrain that can stand up to the current motor and get the job done. Put in larger than is really needed and you could be chasing drivetrain upgrades for some time to support it. If you change the engine only do so because its worn or as I did to improve fuel economy and lower operating costs. It adds up at the end of the year and then as the years pass by. My wife's car uses on average $250 a month more fuel than mine does to drive a similar amount of miles which comes out to an additional $3,000 per year so $30,000 at the end of the decade and both are similar in size. What could you do with an extra $30,000 every decade? Best!
Good to finally meet the man in the background...Jordan. Nice work Colby, Dillon and Jordan Matt is doing a great job teaching all of his crew to do recoveries. 6 liter would be great to see plus the install.
I'm building a '74 FJ40 and I'm having the same mental battle about engines myself. The 4.2 straight 6 is great for crawling, but I can throw an LS in there with an NV4500, save almost 500 lbs over the factory drive train, and have more off-idle torque. What did you decide, Matt? It will be towing a lot too. Also, What is your take on BTR's Truck Norris cam?? LOVE, LOVE, LOVE your contend guys!! My wife and I can just sit and watch without my finger on the mouse button or the pause button on the Roku remote. Just good ol' fun edutainment stuff. We are moving from GA to the UT, ID, NV area within the next 6 mos. We have boys in both BYU's. Maybe we'll run into each other on a trail! Hopefully, it won't be at the end of a Yankum Rope!! LOL
If the Morvair engine dies then upgrade, other than that, don't fix what isn't broke. Add a new vehicle with the upgraded engine if desired. Don't forget, bigger engine will likely need a lot of other upgrades with it to handle it.
My opinion the perfect setup for the morrvair would be a 6.0 with flat top pistons and 862/706 heads to bump compression and a BTR truck norris cam. That combo would give quite a bit more low end torque then your stock 5.3 and let it rev to 6500 rpm for those long sand pulls in the dunes. The stock 5.3 cam is done at about 5300 rpm and way down on power by 5500. I would also install a 4 corner steam port kit that will help with cooling a bit too.
A Gen3 iron block 6.0 with headers, a BTR truck norris cam kit, and TBSS intake would net you a solid 500hp/tq with a nice smooth power band on 87 octane gas. This is the setup I have in my 85 C10 long bed and it will roast tires without issue but also easily pull my 20ft trailer with my 87 Jeep YJ on it while getting 15ish mpg. As a former Army 63B I can say I have never seen a ball joint rip out of the upper control arm like that, I have seen ball joints come apart and I have seen the mount rip out of the frame though.
I love that you guys know you're so underqualified that you didn't even try to pull off being the C team and went straight to D. 😂😂 Handled like the professor himself.
Your pulling around big tires and other rigs. Yes, more motor. But naturally aspirated, maybe lt 6.2. Does chevy still make the zz 502? All aluminum about 500 hp reliability
IKR. How many towing companies would go out to your vehicle, diagnose the problem, go to your yard and pull off a part then go back and fix the vehicle? That's service. It wasn't outlandishly difficult but most places wouldn't have done that.
The Morvair is a great troop transport/recovery vehicle, in that order. Do a good 5.3 build, no crazy power or torque, and have it waiting for whenever that original mill gives up. More power=more cost=more problems=more costs, and on and on.
I agree 100%. The Morrvair's 5.3 has proven powerful enough to break components in the drive line at least twice (maybe more?) Two sayings come to mind, "If it ain't broke, don't fix it!" and, "Don't go buying trouble. It's free and it knows where you live."
If you are "bent" on dropping a new engine in the Morrvair, I suggest something in the 6.0L range built as boat motor. Think torque, NOT high rpm HP. Basically the same thing as what you have now but with a touch more grunt.
With a built motor, you start having to improve everything else. That's when it gets expensive. More fuel, exhaust, transmission heat, transfer case heat, and snapped axles. More power isn't always the answer.
I think the 6.0L would be amazing. I did not know that you can put that big an engine in that Lakewood, but hope I can see the finished product, either in Utah or in California! Recover on .....
Could use a rebuild to tighten things up. Wouldn't need a bigger cam if did more efficient roller and bolt ons. It would gain more power and torque naturally. Would still need different cam, but a roller cam. Roller rockers, forged pistons and push rods, timing chain slack adjuster, underdrive pulleys, multiple electric fans, additional Trans cooler. It would be 11% MORR efficient, 100 extra HP and 45 pounds of extra torque minimum. I did a SB350 19 years ago in my 91 Silverado and it still has tons of HP & Torque. So much it chirps second gear with an automatic when I stand on it still to this day.
Those A-arms on the Hummers are a common failure point. In the Marines we had a brand new, less than 520 miles on it, M998 that someone was driving along the border and caught a lip on a cattle grate, tore the A-arm half off.
That ball joint mount is such a terrible design. There's almost no support at the end of the control arm. I'm surprised they don't fail more often honestly.
And with no pic of the problem, I hope they get billed for all the extra time involved. The company should have had the part pulled and available for the team to pick up on their way to finding the problem HMMWV. What a poor way to run a business.
Love the channel, and the Morrvair has been an amazing rig, a total workhorse!!! It never overheats, never leaves you or your customers stranded, and has never failed to unstick some of the most stuck vehicles. It's your money and who am I to tell you what to do with it, but unless you find the Morrvair suddenly struggling or letting you down honestly I would not swap the motor. 😁
@@doug112244there are several different tours as I recall. We went to the top of the world, the flintstone house, the toll booths and the infamous bobsled. In fact the same hummer we were on broke down on the bobsled the next day. It was featured on a MORR video the next week. (10/23) Check out their Google reviews you’ll see my review and many others with pictures.

I have an 06' Silverado 2500 2wD 6.0L with 320,000mi AT still going strong and tight. We use it as a company workhorse pulling trash and tool trailers, hauling building materials and running errands. We've owned it since 90,000mi back in 2014. Maintained regularly scheduled maintenance, tuneups and all the standard attached running gears, bells and whistles. It is an impressive engine. We also own two other Silverado 2500's with the 6.0L 4wd AT 06' and 05'. Both engines going strong and tight with regular maintenance and tuneups scheduled and diligently followed.
I don’t drive the Morrvair, obviously, but from what I’ve seen it has lots of go and has never bogged down. It looks good to me as it. A bigger engine may be a nice to have thing, not a need to have thing.
I feel like this is a rhetorical question! 10,000,000% yes to new engine!! Mo Powa!!!
So many times, I see people just "add" or "install" a blower and don't fully understand that going Forced Air requires a lot of changes to the engine, like the correct Blower Cam, bigger injectors, boost-a-pump or a bigger fuel hat, optimum compression, Etc. Then there are those who only plan on "a little boost", maybe 10lbs and fail to recognize that the demand a blower puts on an engine and only running a little boost is actually losing power or if anything just a wash. If you're going with a supercharger you need to understand the advantages and disadvantages of Centrifugal, vs Roots, vs Twin-Screw. And of course, the relatively new Electric blowers that take some real talent to correctly tune.
Fuel sump/surge tank and let er eat. You're wrong about parasitic power. Get a magna 4303 and pwm controller on fuel PSI if you're out of fuel... The LSA with the blue/red ECU is instant 4-8 lbs boost @ idle and has a sane bypass to not overheat intake charge. Need an intercooler, but it's sane up to ~8lbs boost on 6.2 liters.
I don't recall seeing many videos where I thought "man, the Morrvair could use a little more grunt." The way you've got that truck geared seems to work pretty well with the power the 5.3's giving you. A healthy LQ4 would be nice, but I don't think you need to consider that until the 5.3 starts giving you grief that you can't keep up with.
@@boaz_macphereson BORING
@@alistairbartlett1930gotta get them clicks!
@@Eyes0penNoFear im all for the new motor spend all the money
Would it alter weight? Morrvair seem really well balanced for its requirements, additional weight up front would change everything.
No the 6.0 is same weight@@russbell6418
Peanut was embarrassed that she was on camera when she cased it tryn to get on the trailer.....such a sweet dogo ❤️
Regarding the morrvair engine, if it ain't broke, don't fix it. Bigger engines, means bigger power. Which means the possibility of more expensive parts breaking.
Kolby and Jordan really impressed me with their trail repair
Wow, nice new video view... like the new wide angle view of this video. New camera, new settings. What ever this is I like it. Easy on the old eyes! Thanks and kudos to the camera/video people!!! 🎥
For the Morrvair, have him build you a 5.3 with a little bit of cam and some mild boost. That’ll be plenty and won’t be too much of a maintenance headache.
One of the features that keeps your fleet reliable is not having too much fancy and finicky stuff.
Leave the Morrvair alone, it’s got plenty of power and if you raise the power you will start busting stuff. You need it dependable. You guys rock
As a fellow bald dude, you gotta get Jordan a hat! My head got sunburnt just watching him out in that 100 degree sun.
With a shaved head, you can use sunscreen for your head. And it's cooler than having to wear a hat.
He might be one of us weirdos that just builds up leathery dark skin on his head..... I only wear hats out of desperation, never remember to lube up the skull with sun block. I usually end up with a sunburn first part of the year, but after it's burnt once, I do alright. 6 hrs on the jet ski the other day added some color.... companion that was with me had sunblock and ended up lobstered. She called me a mutant.
My boss got skin cancer from shaved head and exposure. Had to do months of topical Chemo and head cover.
ALWAYS REMEMBER BROTHER + FRIENDS, "grass doesn't grow, on a busy street". Shaved/bald heads are beautiful, indeed!! Rock on brothers! 👨🦲
@@paultrujillo9923 My Dad would say that and I'd ask him, "You let people walk on your head?"
Definitely put a larger motor in the Morrvair!!!! 6.OL with some cam would be sick!!!!
Injectors, fuel, and compression. ALLLLL the compression.
Amazes me it can be hot and humid in the desert. Strong bench means you never run out of talent. Nice job fixing/recovering the humvee.
Brother hailing from Arizona, monsoon season can be deadly -105F + 40% let's gooooo. These folks are cut from a different cloth. Rocky mountain strong is a different level.
Colby is an unsung hero of MORR, what a guy!
The issue with most of the LS family of engines for rock crawling is the short 3.622" stroke most of them use. Only the LS7 uses a 4.00" stroke. If you need a bit more power and fuel economy is a consideration, I would stroke the 5.3. With a 4.00 stroke, you would increase displacement from 5.3 to 5.8, and a 4.125" stroke would be a 6.06 liter. Put a longer stroke in it for the increased lower rpm torque and make sure you are cammed, convertered and geared to match the RPM you want to run. My suggestion is build it for low RPM torque, and stroke is the way to go. If you turbo, go small turbo, low boost, so it's useable in the low RPM ranges. Don't compromise your compression ratio for the sake of a high boost/RPM power numbers. Regardless of the way you go, you must match your components to get the best performance for your spend. When you get the combo right, you will not have to work the engine as hard, it will run cooler, and get better fuel economy.
I have a 2015 Silverado with a 5.3 and at 210,000 miles replaced with new engine. A lifter ate up cam lobe other than the 4 to 8 cylinder bull that I stopped with a chip in the diagnostic port plled my 30 ft trailer just fine. Now have new brakes, struts,shocks,tires (ko 2s, it's a k1500), radiator, it's my last Chev pickup of my life. new truck. At 80 y/o a new truck would just be a rental. My 2008 f350 has 222,270 on the ticker, 6.4 powerstroke, front-end rebuilt, new tires, etc. Great towing, outfitted for overlanding, self recovery, and slight pinstripping. Over time, invested in upkeep, has paid off. I'll be by to visit you fellas this fall. See you then. Maybe this time I'll finally meet Matt, then have another old man story swap with Ed.
Man it’s nice seeing dad and son together looking soo relaxed. God is good!
I like a big cams, big compression, tight heads, lots of carb. Almost blew heads off a 283 cu in, used 327/ 375 hp cam, stock heads, pushed studs out of heads. Found some 327/ 300 double hump heads. The studs were pinned. Made lots of power for a mostly stock motor.
On the Morrvair, it works. Has the power ever been a letdown? No point in having more power than you can put to the ground. I'd be temped to change the engine for it's "younger sister" just to keep it reliable.
Keep it reliable. You've got it to the point that its got a drivetrain that can stand up to the current motor and get the job done. Put in larger than is really needed and you could be chasing drivetrain upgrades for some time to support it.
If you change the engine only do so because its worn or as I did to improve fuel economy and lower operating costs.
It adds up at the end of the year and then as the years pass by. My wife's car uses on average $250 a month more fuel than mine does to drive a similar amount of miles which comes out to an additional $3,000 per year so $30,000 at the end of the decade and both are similar in size. What could you do with an extra $30,000 every decade?
Best!
Keep it stock and reliable. You have relied on it for quite a while. Don’t introduce questions into your daily routine.
Where's the fun in that?
BORING
The lsa is extremely reliable and stock for a cadillac, camaro and vette
That stock 5.3L gets the job done just fine and very reliable at the same time. Leave it alone.
Agree more power=more issues.
Good to finally meet the man in the background...Jordan.
Nice work Colby, Dillon and Jordan
Matt is doing a great job teaching all of his crew to do recoveries.
6 liter would be great to see plus the install.
Great to have Jordon there with his skills and the rest of D team working hard ✌🏾👍🏾👍🏾
I'm building a '74 FJ40 and I'm having the same mental battle about engines myself. The 4.2 straight 6 is great for crawling, but I can throw an LS in there with an NV4500, save almost 500 lbs over the factory drive train, and have more off-idle torque. What did you decide, Matt? It will be towing a lot too. Also, What is your take on BTR's Truck Norris cam??
LOVE, LOVE, LOVE your contend guys!! My wife and I can just sit and watch without my finger on the mouse button or the pause button on the Roku remote. Just good ol' fun edutainment stuff. We are moving from GA to the UT, ID, NV area within the next 6 mos. We have boys in both BYU's. Maybe we'll run into each other on a trail! Hopefully, it won't be at the end of a Yankum Rope!! LOL
MORRvair is a workhorse with elegance. Don't change a thing. Not broken, don't fix.
I agree.
Way to go "D Team"! The depth of the MORR personnel roster is amazing.
If the Morvair engine dies then upgrade, other than that, don't fix what isn't broke. Add a new vehicle with the upgraded engine if desired. Don't forget, bigger engine will likely need a lot of other upgrades with it to handle it.
My opinion the perfect setup for the morrvair would be a 6.0 with flat top pistons and 862/706 heads to bump compression and a BTR truck norris cam. That combo would give quite a bit more low end torque then your stock 5.3 and let it rev to 6500 rpm for those long sand pulls in the dunes. The stock 5.3 cam is done at about 5300 rpm and way down on power by 5500. I would also install a 4 corner steam port kit that will help with cooling a bit too.
Great job on the trail repair, guys!
11:00 - Wasn't Matt a Roofer for a long time before MORR took off? His hands are used to dealing with some of the hottest stuff.
Jaymee
More motor = breaking more stuff. The Morrvair is pretty solid, leave it alone and let it work.
Colby is so humble! His team swapping out part and being the H1 back to it’s stable is on par with Matt’s recovery
Do it! Go with more power and entertain us by replacing the drive train little by little as they break. 😅
Is more content. We love it!
I was curious for a while who the quiet guy was. Nice to meet you Jordan. You fit in nicely with the others.
Has had been mentioned already. If it ain't broke don't fix it. The morvair is a tool not a toy
That ain't no air cooled 4 cylinder 🤣🤣
Seems like you recover a lot of Humvees and this company seems to have lots of spare parts for when they break. Great recoveries.
Great behind the camera, great in front of the camera, great under the hood, Colby's a very capable young man.
Yes, yes. yes!!! 4:04
Good to see Jordan on camera more and on the trail
As a mechanic I have to quote our credo "if it ain't broke don't fix it"
Exactly.
I have to agree! Simple and enough power keeps things reliable for more years of work!
And leave well enough alone
BORING
Or upgrade before it degrades! 😅
"Can we Get a Razor ? " - No 🤣
Matt is a very wise man.
@@4knanapapa Wisdom in one word!
I suppose Kaulin will have a beard soon too !
A missed opportunity for a “we have 🪒 at home” site gag.
😂😂😂
A Gen3 iron block 6.0 with headers, a BTR truck norris cam kit, and TBSS intake would net you a solid 500hp/tq with a nice smooth power band on 87 octane gas. This is the setup I have in my 85 C10 long bed and it will roast tires without issue but also easily pull my 20ft trailer with my 87 Jeep YJ on it while getting 15ish mpg.
As a former Army 63B I can say I have never seen a ball joint rip out of the upper control arm like that, I have seen ball joints come apart and I have seen the mount rip out of the frame though.
Nice to see Jordan out!! Good wheeling
That be cool to see but the morrvair don't seem to struggle with what it has that thing is an ultimate beast of a machine
I love that you guys know you're so underqualified that you didn't even try to pull off being the C team and went straight to D. 😂😂 Handled like the professor himself.
1st rule of maintenance for ANY kind of equipment - If it ain't broke, don't fix it.
Leave the Morvair alone.
Your pulling around big tires and other rigs. Yes, more motor. But naturally aspirated, maybe lt 6.2. Does chevy still make the zz 502? All aluminum about 500 hp reliability
handy to have a capable mechanic along on a recovery!
Good to meet a new member of the crew.
Team “D” for Damage Repair! This was an incredible rescue.
IKR. How many towing companies would go out to your vehicle, diagnose the problem, go to your yard and pull off a part then go back and fix the vehicle? That's service. It wasn't outlandishly difficult but most places wouldn't have done that.
The Morvair is a great troop transport/recovery vehicle, in that order. Do a good 5.3 build, no crazy power or torque, and have it waiting for whenever that original mill gives up.
More power=more cost=more problems=more costs, and on and on.
I agree 100%. The Morrvair's 5.3 has proven powerful enough to break components in the drive line at least twice (maybe more?)
Two sayings come to mind,
"If it ain't broke, don't fix it!"
and,
"Don't go buying trouble. It's free and it knows where you live."
That shot of Matt holding the gate open gives me a great idea for a MORR teapot for the merch store
If you are "bent" on dropping a new engine in the Morrvair, I suggest something in the 6.0L range built as boat motor. Think torque, NOT high rpm HP. Basically the same thing as what you have now but with a touch more grunt.
1:44 LOL at Kaulin's exhausted sigh while the celebrity dad is posing for a fan
That mechanic Jordan is a keeper!
With a built motor, you start having to improve everything else. That's when it gets expensive. More fuel, exhaust, transmission heat, transfer case heat, and snapped axles. More power isn't always the answer.
I second this.
I think the 6.0L would be amazing. I did not know that you can put that big an engine in that Lakewood, but hope I can see the finished product, either in Utah or in California! Recover on .....
Could use a rebuild to tighten things up. Wouldn't need a bigger cam if did more efficient roller and bolt ons. It would gain more power and torque naturally. Would still need different cam, but a roller cam. Roller rockers, forged pistons and push rods, timing chain slack adjuster, underdrive pulleys, multiple electric fans, additional Trans cooler. It would be 11% MORR efficient, 100 extra HP and 45 pounds of extra torque minimum.
I did a SB350 19 years ago in my 91 Silverado and it still has tons of HP & Torque. So much it chirps second gear with an automatic when I stand on it still to this day.
Those A-arms on the Hummers are a common failure point. In the Marines we had a brand new, less than 520 miles on it, M998 that someone was driving along the border and caught a lip on a cattle grate, tore the A-arm half off.
For the weight of that vehicle, the stamped A arm looks like it might as well be made of aluminum foil.
8:55 Using the shock method of getting ball joints loose! Keep that guy.
Man, those tour hum v's must get the crap best out of them. I've seen them needing rescue quite a few times. The savior of MORR
That ball joint mount is such a terrible design. There's almost no support at the end of the control arm. I'm surprised they don't fail more often honestly.
And with no pic of the problem, I hope they get billed for all the extra time involved. The company should have had the part pulled and available for the team to pick up on their way to finding the problem HMMWV. What a poor way to run a business.
Jordan is like one of the dogs, as soon as you open the door he's off on an adventure!
I think the Morrvair needs at least 800hp. Just think of how quick you could do recoveries!
The D team did a good job.
That humvee at this point should be a paid actor
Yep, they need to do a playlist of all the appearances
You sure it’s the same one? That tour company has a bunch of them.
Not very tough for a military vehicle. Tested on the streets of Detroit, land of many RR tracks.
Military grade = lowest bidder @@brucegrunewald8423
Its a herd of humvees
Impressive acceleration on the Razor, driving onto the trailer!
Enjoyed that Colby and Jordan segment
Love the channel, and the Morrvair has been an amazing rig, a total workhorse!!! It never overheats, never leaves you or your customers stranded, and has never failed to unstick some of the most stuck vehicles. It's your money and who am I to tell you what to do with it, but unless you find the Morrvair suddenly struggling or letting you down honestly I would not swap the motor. 😁
I’ve toured with those RedRock Humvee Tours. It’s 100% the best time ever.
What does a tour cover?
@@doug112244there are several different tours as I recall. We went to the top of the world, the flintstone house, the toll booths and the infamous bobsled. In fact the same hummer we were on broke down on the bobsled the next day. It was featured on a MORR video the next week. (10/23)
Check out their Google reviews you’ll see my review and many others with pictures.
@@doug112244there are several tour options. The RedRock Humvee website has all the details.
Our tour guide was the owner, he was super cool. When I mentioned a couple of sites we’ve seen on the MOOR videos he readily adapted the itinerary.
We saw the sunset at the top of the world, toll booths, flintstone house and had the time of our lives cannonballing down the Bob sled.
@@doug112244 lots of cool stuff.
My favorite was seeing the sun set from the “Top of the World “
@@doug112244 this is weird. I’ve tried multiple times to respond to your question. Something keeps removing my response.
I’m here for the LT engine build for the Morvair. Maybe even a tiny supercharger pushing 6-8lbs. She’d sound more sweet. Maybe even a baby turbo instead.
AGREED! The Morvair DESERVES a Bad A$$ engine.
All your employees should think you are not a mere mortal! That final scene was priceless!

Don't mess with Morvair. You are messing with perfection.
