I've watched yours and it is SWEET! Nice rig and if it'll run upside down it'll run anywhere. Thanks, Mate!

The 3406 has a half inch longer stroke. Bore is the same at 5.4 inch.

I was about to switch to your channel and check in on ya👍 Good to see you're still around!

Are 3408s a bit fragile? We have a Sig Series 02 KW Cummins coming up on 1.45m kms that has the shit thrashed out of it by 5 different people (all of who would be struggling to drive a stick up a dogs arse btw) and its had about 5 clutches and 2 partial gearbox rebuilds. The whole truck is turning to shit but the motor has had 2 turbos but not so much as the head off it. It overheats too. We just leave it alone as much as possible in case it stops lol. I suppose comparing an inline 6 to a V8 is a bit unfair since V8s suffer secondary vibration that inline 6s don't. We have a few 3406 Cats but they don't have the poke on hills our Cummins engines do. Would i rather a Cummins over a 3408 for the type of work you do? Nah I'll take the 3408 (that's the mechanic in me. I like you can open them up and the cylinder bmehp is lower than a 6 as well as the hp being at 1900 as opposed to 2100 ;)

ThePaulv12 I hardly think mine is fragile, just look at the hours it’s done and the weight it pulls in extreme heat. There’s still a few operating here in Australia with bigger loads than mine. As long as you do the bearing rolls, like any early 3400 series, and you don’t lug it below around 1400 rpm, the crankshaft will last. I’m a firm believer in oil sampling every oil change too.

Yes!

V8 is the superior engine design

Agreed Cat, Cummins, Scania they all sound good.

@@chrismckell5353 Mercedes Truck also ... their V8 engines have a particular sound, clearly recognizable

Mack E9. Ultimate sound.

would love to see some footage

Ray McGhee I’m just a wrench but I like the older 60 series. It gets no love. It’s fairly simple , has decent power and gets decent economy. It doesn’t kill any category , just performs well and that’s what’s needed for a workhorse. Done many a engine dyno pull with some guys from interstate mcbee as they were developing replacement injectors years ago. I forgot how many runs we did , but it was over about a 6mo period every few days, and probably 4-6 pulls each time they came. Heh those ol boys learned pretty good how to swap injectors, I think we got it down to about 45 mins with 3 guys.

I also like the 12.7 Detroit 500 hp. Dead reliable pull good and easy on fuel. To bad they stopped making them.

MrHillfolk Lifetime wrench here too , your description is exactly correct , been around them all , young and the old moth eaten stuff too worked on gensets w/v 71 series Detroit's, 1693 cats , all the old Cummins , even the ones w superchargers B's I think , compression releases also, but with the steel haulers and the graveltrains horsepower was/is king .But with the spreading out of the auto industry that isn't what it was years ago.

you can tell by the paint job striping...😊

Bly thkd the best way to get good mpg on the 3408 was lie about the miles or gallons.

Sounded like the trumpet part of the Jurassic Park T-rex .

He said the the engine was fueled. Meaning they turned it up.

@@rrobins9857 like most people do with the newer stuff

Tesla. That is all.

Nowadays they put out those kind of numbers with six cylinders not eight, plus considerably more torque and decent mpg not gpm like this hog. Don't get me wrong, it's cool as all get out, but not efficient.

@@opaqueman5043 we're still pretty far from making capable electric semis. There's just no way to pack the range a massive tank of diesel does with current battery technology.

lol and thats a lot of lizzards and stds to go along with them any videos of the ol days ?lol er truckin videos :)

Dwreck Baker gotta love them lot lizards 🦎

Purring? Pumping? 😂😅

@@biscuitninja he lucky to be still purrin after all those lizzards and STDs

biscuitninja Purring on the outside, pumping on the inside

My first job we had some 3408 Cats in trucks for peddle runs. They were very reliable but he was right in repairs being expensive. Parts are indeed expensive.

1693caterpillar still big power in miss my old 425 it was putting about 575 to the ground

@@justinlopez4806 Now that's a real ground pounder.

I haul logs out of Louisiana we’re always over not very many trucks around could have kept up with her unfortunately we got rid of her because body was falling apart it was all there though

Everyone forgot another powerhouse 12v71

Justin Lopez didn't forget it, it just wasn't in the same realm as the big dogs.

WOW!!!!

@@camelmanjd2671 Yes Sir , It was in a Long Nose W900 KW , Double Over 13spd, 3.55 Gears . That thing was an animal ,owner had a driving award for 138mph from the state of AZ. Owner said " Shit I was on the Jake for a 1/4 mile for he clocked me !!!"

Knew a guy that had one twin turbo that was putting 1050 to the ground.... Something must have been choking the quad if it only made 900...

jkdwayne we had a black w900L that was a glider kit with a 6nz cat it was tuned and all that and it’d go 132mph. Lost it a couple years ago when our driver lost control in the smoky mountains and had to use the runway ramp. Hit the pit so hard it snapped the frame on the truck and ripped the steering axel off

jkdwayne 3408 don’t have a jake guy

Fuel is an issue today... I have no idea which old and new engines are the most fuel effiecient... Guess alle the elctronic injection and working together with the auto transmissions works for better fuel consumption. But all the emmisions after treatment works the other way... Just a thought and in no way an expert opiniun from me

Up to 900 with marine cam and turbo.

Laiken Bellesario is that a gasoline engine? The horsepower and torque numbers are really close.

post video!

Anatoliy Dashkevich Yes it’s a gas engine. It’s a 454 LSX with twin turbos. Finally found a great tuner in Florida. Low boost in 1st gear. Maybe 7 pounds. 2nd gear 10-12 Pounds, 3rd gear 16 pounds and 4th gear it rips at 24 to 26 pounds of boost. It’s had 100+ dyno runs and 300+ passes at the strip. Texas Speed & Performance know what they’re doing.

What a ass .

Let's see your Chebbie pull Monteagle @ 80,000 lbs tough guy! LOL!

Uh Cat makes better v8s than Scania also can your Scania turn 1000hp with 2 parts changed and a tuner a 3406E Cat makes about 600hp max and gets 6.5 to 7 American mpg or about 10 or 11 euro

Plenty of parts are interchangeable though. I’m rebuilding a spare 3408 truck engine and a lot of part numbers are the same, except for heads, block and crank of course. Water pump and oil cooler are different too.

You can make it a b model 3408 by putting a b model crank and cam in it convert the fueling over to a b model cut c16 pistons in it c 18 connecting rods and a 3508 turbo and marine heads then you can put some real power to the ground

@@bryanwilson5011 And hope that offset crank won't break. Why don't you think that truck pullers use the 90 degree Mack V-8? Because it is nearly indestructable. Caterpillar 60 degree V-8 (from a shortened 3412) crankshaft is weak and cannot take much more than 800hp reliably. Why don't you think that Caterpillar doesn't make the 3408 anymore-in favor of the superior C18?

@@Tchristman100 that's why they put the b model crank in them old tc cats bud in 1987 v8 cats were b models bud that's why you cut in c16 pistons I mean really you need it all spelled out for ya

@@bryanwilson5011 Really sort of a moot point now since the only 3408 that Cat makes is the G model for natural gas with spark plugs putting out a measly 425hp maximum. They do still make the 3406C mechanical (like my 3406B jacket water aftercooled).

a world and i say a world of difference from the 3200 series lol

nope there is more

Curt Ray no doubt there are more. This is the only one I’ve seen.

And it's a glider? Maaaan that is niiiice, real niiiice!👍

I had a “real” one not a glider with a 5x4 trans

that's a glider it was put together and put why it's a 1990 mid Pete with a 1983 V8 cat

That's for sure. Even more so if you happen 2 b running a 3412. Yes they DO exist in trucks but very rarely. Nice rig.

@@paulkirkland1535 yes they do but to heavy for American trucks. See them Australia

No it is a 13 speed now.....

Cool story but it’s power didn’t break the chains lol. Must have been a weak link. 1700 foot pounds torque and 600 hp doesn’t equate to much in today’s standards with what goes on these dynos. It was powerful for its day but the worked over 6 cyl are putting out way over that in torque and you have trucks with worked over cats and Cummins putting down over 1200 hp on these dynos. So no, this 3408 didn’t brake those chains because of its power

you can get a truck like for 40-60k. expensive but def dont need to be a millionaire. get to work

That isn't how you get to 1.8 million miles...

Me tooo ! May we both Win!

Is that the normal torque for a 3408? Figured it would be higher. I’m sure tweaking can be done to increase horsepower and torque.

Excellent point you made. As one who's lost $400 a day for the last 20 work days because I can't find an available $189 an hour mechanic to take me within 4 days after I call them I'm calling a mobile mechanic and just crying uncle. Don't forget about the DEF fluid cost which could be as much as four cents per mile and then those DEF filters are like $1,500 so yeah.... I might hop on the spreadsheet and try and drill down more on this. But for me, hauling intermodal containers, I pretty much have to get 6 miles per gallon but I still use a pre EGR pre ELD tractor to do it. If I were in higher paying freight I think I could stand a five mile a gallon truck.

Dan R that’s no shit half of my bosses trucks have preemission motors again 2-08 and 1-12

That is very well put: making them only last until the warranty period is over. I just don't think heavy duty diesel engines can take all the emissions b******* that gasoline car engines can with without consequences.

true, but they have refined diesel fuel for cleaner burn, less lubrication now so wears engines faster. I would imagine regular early oil changes with a good fuel additive they should all go 800k+

Neither of those 2-strokes could ever out pull a Cat, even if they had more hp

vsTerminus hello. Is this the same guy who makes engine mods for ets2 an ats? If so thanks for the work. I really enjoy using your Mack engine mod.

You can make it a b model 3408 by putting b model crank cam and fueling system cut c16 pistons in it with c18 connecting rods marine heads and a 3508 turbo then you can put some power to the ground

​@@bryanwilson5011 can't put a 3406 cam in a v8🤦‍♂️

That's about average I think. 5 at best.

Second Nature Lawn Care 3.5

4 was a good number you could turn them to 400 horsepower on both sides and still do 4 mpg engine brakes were the reason they dropped it in us. Was still available in Canada after 87

550hp 3406's were putting out 2000 ft lbs box stock nearly 20 years ago .. this 3408 is less powerful than 550 and 600hp 3406E's.

No , because 3400 series cat don't have a rocker arm for injectors ( which is used by a jake ) 3406 uses a adjoining cylinder rockers to triger the jake the timing of rocker arms don't come out wright for a 3408.

Direct drive

Every dyno, whatever the vehicle type, always done at direct ratio (1:1). On semi truck like this, if it got 13 speed or 18 speed eaton fuller, the direct ratio is on 7H gear (11th gear on the 13 speed eaton or 16th gear on the the 18 speed eaton)

yup, but the Scania can do 6.5 mpg easy...

Our 08 Cummins only gets 4.5 mpg . Had a friend had that had a 84 model 3408 that would get 5.8mpg pulling doubles 1300 bushels of grain!

My C15 gets 4.5 pulling 160k.

Modern engines have the pollution control, which unfortunately, and somewhat counter-intuitively, uses MORE fuel.

Benjamin Esposti Dumbass regen that uses fuel. Smh, so dumb. Modern diesel emissions equipment reminds me of the year I was born. 1973. Let’s slap some shit on here to choke power and kill fuel mileage, and still not be all that clean. But look at cars now, who drives a new car home and cuts the cat off anymore? Besides the engine management issue , it won’t really add much more power even if you retuned for it. Modern gasoline emissions equipment actually works and isn’t much of a hinderance. I won’t buy a 08 or newer diesel, I’ve gotta resort to my old toys now.

Ive worked on all of them.... Cummins and new detroits are SHIT.

@Jim Allen not true... At all.... Any mechanic knows that...

Shit? Give me a break! 90% of the motors in our shop are Cats. On the rare occasion we have Detroit, it's more often than not a fuel or blower problem. Almost never mechanical.

@@SgtStickyTits notice I said NEW Detroit's. It's sad a shitmins can't even go 100k without a cam lobe shittin the bed. Series 60 Detroit's can't even go 75k without shittin the rear or front main seal. I worked for caterpillar for 7 years. I worked for Cummins for 6 months. I quit Cummins when I found out what a bunch of fraudulent fucks they truly were. Ship a cam to us with "MADE IN USA" on the box. Pull the cam out to find shitty grinds and shitty hard faced surface. Look on the end of the cam and see "MADE IN BRAZIL" the fuck? Call Cummins. "The camshaft are casted and hardened in Brazil then shipped here. The finishing process is done here. There for its "MADE in USA" " uh.... That's not the way it works.... But... Ok. Every single cam we replaced lasted between 65k and 100k. The shop wound up habing to replace a guys fully built and tuned 800hp big cam 400 because the cam was hollow 😂

@@robby844 You must of worked at a shop with a bunch of morons working there because I have had #2 Big Cam 3's and a Big Cam 4 and they ALL had over 1.5 million on them without ever being apart or rebuilt and the factory installed camshaft still in them never replaced.

That was me and my dads old truck there was 7 of them all the same color just diff years and motors
