1000hp Cummins conversion (4x4 CHEV)

[@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!

[@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.

[@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

[@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 🤩

[@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 🤙🏻

[@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.

[@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!!

[@craigjensen4179]

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

[@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!!

[@joshuabamford5396]

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

[@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.

[@PatrolLuke]

What a wikid build! Keen to watch this one.

[@huntsnewy]

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

[@fobbitoperator3620]

Best body style of any pickup on Earth!

[@teejayhoward]

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

[@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

[@jamesk4455]

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

[@TJANDMAC]

Thanks, will do James !

[@FlyingSpaceOstrich]

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

[@hiddenwatersflyfishing]

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

[@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!

[@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 😝

[@reddo84]

Soooo good! Great episode and progress Cheers Jim

[@JamieWilliams-j9z]

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

[@macpreston]

hahaha legit

[@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.

[@shanenorwell8580]

What an awesome build guys, pumped to watch this.

[@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 😎

[@jmac822]

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

Spooly boi is gonna be wild hey

[@dylanfrench9412]

Love what you blokes are doing. Brilliant channel 🤙

[@TJANDMAC]

Thanks so much !

[@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.

[@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

[@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

[@chrisledwith3216]

Still a better love story than twilight

[@macpreston]

HAHA yes couldnt agree more 😂

[@davegalassi2552]

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

[@TJANDMAC]

8speed.au They are located in Brendale, Brisbane

[@Riley.695]

Nice patio ornament Mac🧐

[@macpreston]

😉😉

[@craigjohnson7409]

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

[@macpreston]

Grid heater is deleted thats for sure!

[@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.

[@SUPERTRUCKER166]

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

[@macpreston]

Diff oil filters are interesting!

[@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

[@nathansingle9698]

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

[@mitchharper9300]

Coolant filters prevent cavitation mate. Like the work 👍

[@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 😂.

[@benpalermo9267]

jeez i love these guys so much

[@TJANDMAC]

🤩🙏

[@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!

[@JimmyL-r5t]

this build is going to be so sick👌

[@RustnDustoffroad]

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

[@jakeotto7508]

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

[@joshuajohnson4800]

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

[@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 🤣🤣

[@macpreston]

Haha sounds like a race to me!

[@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 💪

[@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

[@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

The original 205 t-case you pulled out is stronger than any 79 or 80 series t-case.

[@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.
