1000hp Cummins conversion (4x4 CHEV)

[@Rossco139]

Im doing something similar with an old 67 C30. I cannot say how awesome it is to see this being done! Cant wait to start.

[@dodgyfab1231]

I love these old American utes so much. My dream one is a 1970 f350 dually 4x4. I’m so keen to watch this thing progress and it’ll be sick seeing it with the Cummins in it.

[@bamafencer12]

Ahhhhhhhh! It's like Christmas day! Been waiting for this build series. As an American that loves older trucks, especially Chevys this makes me so happy. Those trucks are well built and won't let you down. Easy to work on. All I drive is older trucks. Y'all Enjoy the hell out of that truck! Cheers TJ & Mac 🍻

[@TJANDMAC]

Thanks mate always great to hear we have American viewers 🙌 thanks so much 🙏

[@macpreston]

Cheers mate! Cant wait to enjoy it on and offroad!

[@mikemorgan4670]

Great to see you back in the shed doing what Macca does best! This will be fun!!

[@TJANDMAC]

Yep the big Chev is gonna be a beast

[@geofftuck7347]

Ahh been hanging for this build for what seems like ages, Maca you didn’t disappoint!! Compound turbos, built axles and coil overs to come too!! Man this is going to be a beast on the tracks 🤙🏻

[@NateH-qd7bm]

Super cool to see one of those old trucks getting somewhat of a restoration

[@TJANDMAC]

Yep gonna be a big build 😅

[@aaronmcclanahan7870]

Looking forward to seeing the whole build

[@TJANDMAC]

It’s going to be a rippa 🤩

[@brianwayne3029]

A coolant filter traps scale and corrosion buildup in the cooling system. Our larger farm tractors all had them. Over the road semi trucks often do as well.

[@joshuabamford5396]

Can’t wait to see this monster finished! K20 for the win!

[@craigjensen4179]

What an awesome build series this is going to be. Keep in up boys

[@roningrae]

Metric tap drill size is thread diameter minus thread pitch. Example: M14x1.5 14-1.5=12.5 tap drill size

[@richardwalsh5570]

100 percent 🎉

[@macpreston]

Bloody awesome to know thanks!!

[@SamYoung4x4]

EVERYTHING NEEDS 1000+ HP! 👑🔥

[@TJANDMAC]

🤣 how about 2000nm ? 😜

[@huntsnewy]

Heaps cool! Cant wait to see it done!!!

[@rainbowags7168]

love everything about this, i had one of the nicest looking OBS f250's with a 7.3L powerstroke here in sydney, recently sold it. this video makes me want to get a chev now haha.

[@TJANDMAC]

Haha yeah for sure! , it’s gonna be a big build 😝

[@rouseyanglerholics]

Love this build! Always loved these style rigs. Looking forward to seeing this completely finished. One day I’ll find an old F100 or F350 like dad use to have and build on up.

[@TorqueMediaau]

I’m beyond excited for this build!!!

[@jessetink3753]

Welcome back lads. Hope you had a good new year and chrisy 👍🏽🤙🏽

[@macpreston]

Thanks jesse you to mate!

[@coreybrown1703]

Coolant filter is for slow release of SCAs in the coolant to maintain required levels. In particular blocks prone to cavitation require correct SCAs kept up. That's be my guess for the filter. The filters come preloaded with SCAs. Is a thing with trucks, pooley would know being a cummins dude..

[@TJANDMAC]

Ahhh true !

[@OzzyFarmer75]

It is not so much a filter, it contains anti corrosion chemicals that are slowly leeched out into the coolant as it flows through. Standard fit on earthmoving and mining gear with larger engines than standard light vehicle engines.

[@wildcustomsandmechanical6528]

That 8speed will last one decent drive

[@macpreston]

I dont think it will last the dyno run haha but what we have planned for the second 8 speed will be sweet!@@wildcustomsandmechanical6528

[@macpreston]

Ah makes sence ive learnt something new!!

[@danielalamo2075]

Very cool old truck?? I have a few. I have seen a Cummins engine in this body style about 5 years ago. These trucks, now, are $20k for rusty junk. A worn-out 200k mile Cummins $5-10k. I have already watched most of the other build videos. Great job!!! I prefer to keep mine with the 454 that I put in it. These videos get me wanting to get mine running again. Thanks for sharing your build!! I'm from the central valley of California.

[@TJANDMAC]

Thanks Daniel ! yeah these are very rare vehicles in Australia, hard to get and crazy expensive !

[@fobbitoperator3620]

Best body style of any pickup on Earth!

[@jamesk4455]

Absolutely love the channel. Keep up the great content 👍.

[@TJANDMAC]

Thanks, will do James !

[@PatrolLuke]

What a wikid build! Keen to watch this one.

[@reddo84]

Soooo good! Great episode and progress Cheers Jim

[@TJANDMAC]

🙌

[@hiddenwatersflyfishing]

It would be amazing to see this thing on a trip like the old telly track when it's done!

[@locobogan9588]

Keen for this build 🤙 twin turbskies sounds like fun 🐌🐌

[@davegalassi2552]

Where did the adapter plates come from for the transmission and T case ? Allison

[@TJANDMAC]

8speed.au They are located in Brendale, Brisbane

[@jmac822]

Yes, I've been waiting for this build. Sick😎👌

[@TJANDMAC]

Gonna be a beast

[@jasondaley6723]

Another fun filled episode, the introduction was man

[@haraldkonig8317]

I think a coolantfilter is in there to filter rustparticles from the engine.

[@macpreston]

That also makes sence! A few replies have said it conditions the coolant aswell!

[@shanenorwell8580]

What an awesome build guys, pumped to watch this.

[@tomwhelan7901]

What's the go with the new 79 round the side of the house at 16:30 🤔 new giveaway ? 💁‍♂️

[@macpreston]

🤫🤫

[@tomwhelan7901]

I'll buy tickets if it's a giveaway my 79 due for a tip run amd just leave it there

[@teejayhoward]

Coolant filter guess - They had a rusty radiator or heater core, and used it to catch the metal flakes running through the system.

[@thomjanson9644]

Man, gagging to hear this thing run and spool up.. 🤤

[@TJANDMAC]

Spooly boi is gonna be wild hey

[@FlyingSpaceOstrich]

@9:48 It's just like a usb; you have to try to plug it in both sides before it will go in

[@ko1113]

If the coolant sits in the engine long enough, it tends to react with the iron (or aluminum) inside the engine. The filter is to subtract those small corroded pieces so the rest of the engine will rust less rapidly. (It's basically a sort of anti-rust system.) The coolant filters are commonly used on bigger diesel engines such as cats for bulldozers, but also on some bigger car engines.

[@dylanfrench9412]

Love what you blokes are doing. Brilliant channel 🤙

[@TJANDMAC]

Thanks so much !

[@JamaineObah-mt6sk]

Was panicking for a moment. Thought you and macca had left us, up the Cummins!

[@TJANDMAC]

Never ! 😝 it’s gonna be a beast

[@intimatespearfisher]

boys, I can feel a dad segment coming on. Regular side eps giving dads tips on how to camp and wheel with a miso and kids. Please start with how the camper trailer has changed things for you. TJ what have you been doing mate? Finish the job, your like 37 or something?

[@macpreston]

haha im working on him do youtubers get paternity leave tho?

[@MattysWorkshop]

Gday, I’ve been waiting for this to start, absolutely shit hit build, all the trucks I’ve drove (Kenworth, Mack, Freightliner) had coolant filters, its to catch and scale and shit floating around, top job mate, cheers

[@TJANDMAC]

Oh true ! So it’s a truck thing to have eyyy

[@samwayne5765]

First video I’ve watched of yall, love the truck. That first scene about how impractical and overpriced those old trucks are is on point. Yall might wanna put some captions from time to time, that down under dialect is hard to pick up on for a novice. It’s ok people dont understand southerners either. From texas

[@TJANDMAC]

Great idea ! I will do for the future episodes on this build 😎

[@JimmyL-r5t]

this build is going to be so sick👌

[@Wr3ckit]

Finally! Can’t wait to see it get sent! Wonder if you’ll finish your engine swap and coil overs before I finish my engine swap and coil overs? 👀

[@macpreston]

Haha sounds like a race to me!

[@benpalermo9267]

jeez i love these guys so much

[@TJANDMAC]

🤩🙏

[@sav2762]

OMG FINALLY 😱

[@TJANDMAC]

Here we go 🤩

[@reubend340]

Very keen to see how that 8 speed goes with the mega ton of torque once thats engine is tuned. Im very close to getting one for my 79 thanks to you Maca 😂.

[@JamieWilliams-j9z]

Still newer interior then a 79 series hahah love the content.

[@macpreston]

hahaha legit

[@JakzW-r9f]

1:29 ahhh that's where our pallet trolley went 😂

[@6226superhurricane]

you should keep the np205 transfer case because it's far stronger than the landcruiser one which i have my doubts would last behind a 1000hp cummins that would have around 1700nm of torque.

[@TJANDMAC]

Yep all an experimental process at the moment , turns out the 79 transfer doesn’t work so will be going a different route next episode 😎

[@6226superhurricane]

@@macpreston that's why you use a 205 so you don't have to get one. you can also beef them up as well. the downside of the 205 is 1.96:1 low range but that won't be an issue with the low revving diesel and auto it'll still crawl. and these days you can get parts from usa just as quick as from melbourne or perth.

[@nbenson243]

Where did you get the adapter plat for the 8 speed transmission and what 8hp 8 speed transmission are you using?

[@buildersofarchitecture42]

Came here for the same reason

[@TJANDMAC]

8speed.au They are located in Brendale, Brisbane

[@crimsonstride5457]

man i cant belive youtook everything off the block to paint it lol the one thing i know cummins for is the nice factory red and black paint over every connector and wire

[@struuuth]

Sick truck with that ShedLife twist

[@SUPERTRUCKER166]

Coolant filters are pretty common in heavy vehicle applications as are things like diff oil filters etc

[@macpreston]

Diff oil filters are interesting!

[@JasonMcMahon-h1c]

Because old cast iron blocks rust internally and a filter will stop your radiator from blocking up and keep the engine cooling system running smoothly

[@mitchharper9300]

Coolant filters prevent cavitation mate. Like the work 👍

[@offgrid4x481]

YEEEEEEEEEHAAAAAW BRING ON THE K TRUCK!

[@andyharris1979]

might have coolant filter for when it was in america it gets really cold you might be able to turn it off so truck warms up quicker

[@jakeotto7508]

Loving the content fellas!! I see a cheeky brand new 79 in the background there 🤔 new build giveaway? 🤷🏻‍♂️

[@HardstylePete]

Will the zf hold up to the Cummins? I know they are solid but that motor is well over its rated input torque?

[@macpreston]

We shall see, have some plans for the 8 speed

[@lessworkmoreplayy]

Sitting in the engine bay is good to work on the big rig and it would be even easier without the bonnet on it…….get tj around to help lift it off 🤣🤣

[@Timberstuff]

the box as you call it is a ZF or a Allison?

[@ryanpitts9620]

u using the 8hp gearbox? if so where'd you get the bell housing adaptor made? im looking for one for similar build.

[@hamishjohnson9678]

Mate metric threads are easy to know the drill size you don’t need a chart. just take the pitch off the shank size eg 12x1.75 thread needs a 10.35mm hole, 10x1.5 thread needs a 8.5mm hole, 8x1.25 thread needs a 6.75mm hole ect.

[@danielthornton3277]

Are you guys going to relocate the ECU under the dash or somewhere similar?

[@chrisledwith3216]

Still a better love story than twilight

[@macpreston]

HAHA yes couldnt agree more 😂

[@nathansingle9698]

You normally see those coolant filters on industrial diesels. Lot of Cummins and CAT have them

[@daniellablee6682]

Terrible proyecto me encanta este tipo de videos,por mas felicitaciones👍👏👏👏👏👏🇦🇷🍻

[@TJANDMAC]

😜

[@danielminett6716]

Any information would be amazing, I’m looking to swap my 1960 ford one ton flatbed Dooley with a 12v Cummins but not too sure what to use for a transmission, rear end and front axle.

[@jaybutler6391]

That’s so sick

[@TJANDMAC]

Gonna be a beast 🤩

[@norego6237]

were did you get the cummins i need one

[@TJANDMAC]

Will show ya next build episode 😊

[@macpreston]

Bruce from Rammit conversions

[@charlie2king]

TJ what size and offset wheels you run on your NAV???

[@TJANDMAC]

17 0mm offset 🤟

[@Riley.695]

Nice patio ornament Mac🧐

[@macpreston]

😉😉

[@maccastringer]

I’m frothing this build so hard already

[@RustnDustoffroad]

This is gonna be awesome, keep the patina, way cooler !!

[@joshuajohnson4800]

Was that not a gear driven NP205 transfer case? Why pull that for an aluminum Toyota case? The 205 is basically indestructible.

[@christiaangrobbelaar3338]

Howzit Gents, awesome channel and prob the best build I’m looking forward to. How did you guys start out to get where you are with your shop etc, I’m from South Africa and am really keen to start the same….

[@flipenloony]

What 8 speed do you use mate? Is it a zf? Just watched further and saw it’s a 8hp. All g mate :)

[@TJANDMAC]

Yep same as the cruiser , if it breaks Mac plans to replace with a fully built version 💪

[@Andrew-hu1bx]

Sickkkkk boiz this is that good!!!

[@craigjohnson7409]

Don’t forget the killer grid heater bolts see Gale Banks for these

[@macpreston]

Grid heater is deleted thats for sure!

[@samsymes001]

Caterpillar run coolant filters along with most heavy machinery.. some say helps with keeping coolant levels.. my opinion is saving thousands of dollars worth of radiators and waters pumps if a part fails or corrosion. I'm putting coolant filter on my rig to stop blocking radiator cores if I have a good mob of shit come shooting out of the block!

[@macpreston]

Makes sence for sure!

[@connorexcell1387]

What Tig/mig welder do you use?

[@macpreston]

Unimig mate!

[@BootstrapRevival]

What transmission is that?

[@4WDSKIDS4321]

Omg u guys never have a bad vid

[@TJANDMAC]

Well thank you 🤩

[@jonathantanner9517]

“Gained some time,” man do I understand that statement.

[@macpreston]

hahaha its hard to come by that time stuff lol

[@paulw9293]

Ah someone like me...pays too much then tries to reverse engineer everything purely based on the love for the vehicle & its history! My wife thinks I'm a genius 😂. Luckily for me she's stuck with me unlike many of the poor vehicle decisions I've made over the years...i love this thanks guys! 😊 ✌️

[@macpreston]

haha thats gold! Youll enjoy this one than!

[@lazy6608]

FYI look at most trucks with a Cummins engine they run coolant filters

[@jackjames1543]

Ol simo seems like a top bloke

[@macpreston]

Bloody good egg ol simmo!

[@blair_bsting]

New cruiser in the back there 😂

[@ezandiffy]

cutting with plasma and doing all that work in flip flops is crazy!!! but good job guys

[@cyclemoto8744]

Wicked. cheers lads

[@cameronandrews9286]

Was that a JZ in the shed?

[@TJANDMAC]

Indeed 😎

[@witcher71]

Who is offering the adapters to install the 8HP to Cummins? I hope there's room for radiator. cooling fan and intercooler.

[@TingleTalesStudio-sd4yz]

Yesssssss when is episode two??

[@sumnersmith8819]

What year truck is this?

[@DonnyBool-x9p]

"using a seat belt because we lost the chain" Love it

[@josephparent2226]

You need to get the banks 6.7 intake to prevent engine damage due to the grid heater!!!!

[@omfgishBenneh]

Kid knows the rules, don't like the video til the end. Gotta make sure you deserve it 😂🤙

[@Iamwilczyk]

Chevy dream car 😍❤️

[@charlesboetel1324]

Keeps crap, like casting sand, rust etc from circulating and clogging stuff up. My heater core is full off crap, my oil to water heat exchanger once clogged as well.

[@macpreston]

There ya go! Makes sence!

[@monsterram6617]

That trans isn't going to last behind a Cummins, even in stock form. If you're considering 1000 whp (you've got a long way to go still), you might want to check out what's behind 1000+ whp diesels; a built FMVB 48re. No need to waste time and money "experimenting" when people have already done that for the better part of 20 years and figured out what works best. A 1000 whp Cummins build is quite easy, if you know what you're doing, and there's several (Firepunk, Horsetorque Diesel, etc) who go into the details on how to get there.

[@haydensmith6809]

I see a new 79 series tucked in the corner? 👀
