Both were great engines as well as the Series 60. They were all million miles plus engines when they were properly taken care of.

The amount of knowledge is one thing. Thr rase of explanation and teaching I'd a whole other level. This guy is a wealth if amazing know how.

[@johnmartin6200]

I sure am thankful for people like you. Just bought a 86 359 with a big cam 3 and looking for this exact information.

[@frankpeavy4538]

Definitely brings back memories when I was growing up and riding with my heroes who taught me how to drive. Pretty much every weekend one of us would have our fuel pump taken apart if we had gotten out pulled somewhere during the week LOL. So much more fun and Outlaw then plugging into a computer😁.

[@paulmartin3340]

Man The stuff you know about trucks, diesel engines and associated equipment to keep the wheels turning is amazing!! Speaking of wheels Are you sure you didn't invent the wheel??! Lol Love your videos Ez! Cheers from Sydney Australia! 🇦🇺🦘🐨🇦🇺🇺🇸

Unbelievable I think it would be great to hang with the knowledge and his experience you are so correct

[@DaleDirt]

Love this guy , straight forward ,direct and gets it done with great knowledge and experience . Best part of all is , he shares that knowledge . I have a Pete 358 getting ready to drop a fresh 350 small cam with a 15 speed . Presently it has a 5 and 4 . I would like to keep the aux trans if I have room . I am on a Island with large mountains (Volcano's) so a few extra gears will be welcomed at my experience level . I need all the help I can get .

Love this content keep it coming. KZbin needs more content about big cam Cummins motors

LMAO. Back 45 years ago. The first thing we used to do was change to a number 10 button and some shims. Usually wound up with a number 5 button and shims. JUST SAYING. 🇺🇸🤔🤣👍

Couldn’t wait to get home a watch. Old Red sure has come a long way.

[@Darth-Nihilus1]

Your truck is gorgeous! That’s one of my favorite things about the 855 Big Cam is how reliable they are and easy to beef up. My fire department just retired our 1973/74 Howe International Hendrickson with a Small cam NTF365 that I was able to tune it up to 400 horsepower. Smoked hard and only pulled about 1,050/1,100 ft pounds, it had an Eaton 906B 5 speed. It’s just sitting at the yard since 2017 😭. Great video! Keep her running strong

[@sodapop8408]

That will make that Cummins pull a lot better with those big loads 👍👍

Beautiful truck from a great era, I’m looking to do the same with a COE, cheers from Alberta

[@mybizz8542]

I got a big Cam 350, I put a "0" button in it & a white spring, backed off the Anoroid valve about three threads, shimmed to ,2450 rpm without a load! Shifts at 2100, love it! With 355 gears & a 13 speed od trans and tall rubber she is a Screamer! About 15 feet of black smoke out of the stacks between shifts! An.old truckers TOY!

Good looking truck. Have a good day

[@johnferreira2044]

Back in the day on my big Cam one I pull the bell of the pump and I would pull 5 washer's Sometime more off the shaff for more fuel and put me a 10 button in , I never did mess with the throttle shaft and she only had like a vapor smoke and In the mountains she really pulled good , I would only let it heat up to about 950 on the pro. I know you can go to 10 or 10.5 on the old school Cummins and let them run, but I never did do that always backed out, I got to admit This is the best page for knowledge i been on , Some of these guys that do not know what's going on with there truck they are Definitely learning from you keep up the good work be safe

[@paul2466]

Excellent video Ezra, I have heard some of my older friends talking about springs and buttons and never knew what they were talking about, “Old Red” is a lucky truck👍👍

[@ziggeziggeson5795]

Thanks for the really nice wideo. 🤠🤠🤠👍

[@GNX157]

I wish we could talk more in terms of foot pounds of torque and where in the rpm range. That is the measurement of force that is really getting the work done on this truck.

[@Ezrider359]

That's kinda a loaded statement. Hp is a mathematical formula of tq/rpm. Same horsepower will pull a grade at the same speed but less tq will be in a lower gear. Average power across the curve has a lot more to do with how two engines will perform different at the same horsepower. But that relationship of tq/hp and how it relates to performance could almost be a 20 min video all in itself

[@Ezrider359]

Any time you increase HP in the same rpm range you are also increasing torque

[@GNX157]

It would just be nice to hear the torque this thing puts out and what the increase would be from your mods. I’m more impressed by the torque numbers on any engine, and how flat the curve is.

[@rockchimneyfabrication9838]

Could put a couple extra washers behind the high rpm spring to pop the pressure up a tad.

[@AbcXyz-rn2lz]

I'm researching turbo and pump tricks for a 3406B. The block is basically new

[@Bigmike3406E]

A 20 button is what I always ran in the 400s . That that should bring up your manifold pressure substantially. And throttle response should just crack now .

[@Ezrider359]

I was thinking it would be a bit higher as it has the larger flow injectors and fuel code calls for 160psi rail pressure. I was guessing it would be around a 22-25. But the guy that biult the pump said he set it at 180

[@Bigmike3406E]

@@Ezrider359 It was jacked up . They usually have a 35 button in them.😊

[@anthonymeyer537]

You should stretch the spring a little and buy a 10 button that will live in it up a little.

[@robertquast9684]

I have been leery about doing the button for fear of getting the pressures too high. I have heard that you can put a lot of wear on the cam with too high of pressure at the injectors

[@haroldbenton979]

The 88 IH I drove had over 750 PSI at the rail at max and the cam and followers are still in the truck 24 years later after getting that much pressure. Your never running that hard that long except on the hills. The power is there only when you need it.

[@RipRoaringGarage]

I love watching your stuff. I was hoping that maybe Id get some inspiration for my fuel pump but mine is clearly made with black magic voodoo....no idea how to adjust it yet LOL. Its a Bosch inline 6 and I do know its underfueled big time because I get about 20mpg on a 20.000lb bus. (Sounds great, but no...it has no uphill power at all). But one thing at a time...still have to find a leak..and then modify the brake cylinders. I have a hunch its one or both of them...and these brake cans look nothing like on a US rig...theyre like 18-20 inches long, and 8 inches round. Huge things...Why couldnt I get a 359? Why? lol

[@butterbeansbarstool5414]

The split fuel line to the front head will help a bunch

[@Ezrider359]

I had one on the truck I took it back off for the moment made no noticable difference under load exact same boost egt's and power. mabye a slight difference in throttle response.

[@butterbeansbarstool5414]

they are really simple pumps to work on.

[@bertgrau9246]

I think I would have went with a number 10. then if need be screw in the air valve to cut back the smoke. I have used a number 7 on a 300 horsepower big cam and it woke it up, and my fuel mileage went from 5.8 to 6.25 MPG. A few hills I was having to down shift on, I didn't have to anymore.

[@Ezrider359]

i was guessing it would have a 22-26 button in it so i had got 17-20-22 buttons

I truly enjoyed the lesson. I now know more about the Cummins big cam than I knew before. Thanks a lot. Did the oil consumption stayed the same? Was wondering if it did improve a bit with the new turbo.

[@MrYahoo74]

Add a few shims , let er turn up a bit more 👍🏽

[@staym925]

I got a question, i have a cummins nhc 250, 855 and it won't idle under 1300, at start up it will idle at 600 for 20 seconds, then jumps up to 1300rpms and stays thier. I adjusted idle at pt pump, I've turned down 3 times, and each time idle at 600 then jump up, adjusted again, idle at 500 then jump up on its own, adjusted again, idle at 500 and jump up to 1300 rpms, i can shut truck off, start up and idle at 600, then 20 seconds it jumps up to 1300 on its own and stay right thier. I'm not sure, it don't act like getting air, because don't stumble at all, everytime I start it, it starts right up, no hesitation.

[@moondogdieselworks3883]

Deliverance.

[@dark_one1337]

I remember reading that the N14 has different Liners,Pistons and Rods compared to Big Cams, but you could swap them in a Big cam or any 855 ,but have the block machined to make the Liners fit.

[@Ezrider359]

Yes the n14 and later big cams used lower press fit liners where earlyer big cams did not but the blocks can be cut to fit the later liners

[@rcuev118]

Can you do a video when you test the fuel pressure on the pump and where to buy it and where to plug it in
