- This is part 1 of a series on building a p pumped 6.7L 12 valve, this first video covers about 90% of the work needed to make the engine all work, while the following video will cover final assembly and some detail work (fuel system, turbo, porting, valve train)
This build has spanned over a while so the clips arent constructed in the most streamline fashion, in addition to it being my first attempt at such a engine, however all the methods shown are correct and accurate.

I also carry various diesel related items (new and used) on my website www.hhkperformance.com - ยานยนต์และพาหนะ
It's a breath of fresh air seeing someone try out different combinations to see the real world effects. You are educating us diesel enthusiasts. Keep up the good work!
Thanks man! Ive got lots more in my head i'd like to try out, who knows, maybe this youtube thing will take off and I can share all my zany ideas with the world!
My research on a 12v 6.7l street/strip build said to run the stepped lip stock dodge piston. Turbulence of re-entrant/closed bowl makes it cleaner running on the street. Thanks for the video. I need to get my block to the machine shop.
So far the engine has been running great, Im curious to see in the future how the burn looks with the stock style bowls, I -think- when i measured the bowl position vs the 12v piston it was still shooting in the 6.7L bowl
You can get a straight cut gwar for the ppump its stronger as well.. power driven diesel have some stuff about this for their "godfather" race 2nd gen truck
I did a quick search and wasn’t able to find any product listings for straight cut p pump gears
Hell yeah 👍
At my job we built a 6.7 vp44 to replace a failed 53 block. He's pretty happy with it
I bet it runs good ..
Badass! When I first picked up this 6.7L that was one of the directions I was considering for it. Maybe the next one I build will be a VP44 6.7L with something dumb for compression like 25:1!
Iv been watching you and rob. Your content through insta. Didnt realise or forgot you had youtube. And the panic i felt watching rob hand drill the case holes!
Interesting build, thanks for taking the time to document the build and share it with us!!!
Great video! Can't wait to see how it runs.
Oh hell yeah! Subscribed for MOAR!! This is gonna be cool
I haven't taken notes during a video in a long time. I have a heap of parts and I really want a big stroke p pump for my second gen.
Looking forward to seeing how this runs
The next 2 parts of the video series were just uploaded! Go check er out!
@@Hazardous-Hotrod-Knowledge Nice! Yeah I follow you on Instagram and was psyched to see them on there. Looking forward to watching them!
I like using arp bolts in everything, especially the rotating assembly,
Same here, you can never go wrong with making sure everything is clamped down! This is a budget sorta build so we’ll see what the stock bolts will hold!
so sick!
Thanks! You should see it now that its got some paint on it, I just uploaded the next 2 videos in the series so go check em out!!
I watch CutterUpRob videos also . I now subscribed to your channel..i appreciate the information. I sometimes like to use a bolt thats exactly the right sizei in a hole . I drill a hole through the bolt in my lathe on center , then i can drill a hole in a place that i want it centered.. i might at some point have a p pump 6.7 as long as its capable of given good economy..thanks i believe Robs used GM case sealer on a lot of the areas to seal up
Damn that’s a genius idea! Could probably do it with bar stock, mill it to exact hole size, then have it as a guide too (bolt may be wobbly)
I been looking around for a good mag base drill ..I have a bridge port and a couple more drill press but a mag base is handy on projects . Like drilling a frame or whatever whatever. However if someone comes along and trips on the cord the mag base will fall and real possibility of getting damaged . We used those mag base drills a lot at the power plant
you can get straight cut gear's for your build from power driven diesel
This is a neat build i like something different thats what im into. I used to love the idea of the ppumped 24v till everyone and their brother did it. Im really curious how this one will sound. Also i wonder what it would be like if it was done with the cp3 pump instead of the ppump. Id love to just do all different setups id like to do this build with the 6.7 12v with the ppump like he is doing and id like to do it as a 6.7 12v with a cp3 and id like to go back and do a 5.9 12v with a cp3 and do a old rotory pump for the hell of it on a 5.9 24v and a 6.7 24v just for the hell of it just build all these different setups
HAH Sounds like you've got the mad scientist bug as well! I sorta built this engine for the same reason: WHY NOT! See what happens haha
I run through build combinations in my head daily, I love building engines.
For the 12v head and the CP3, the main obstacle with that is finding and fitting an injector that would work. I -believe- Wagler makes a billet aluminum common rail 12 valve head that I have a picture of saved somewhere. Theres also another youtuber who found and hot rodded a factory cummins common rail 12 valve.
Have you ever worked on a 6.7 FPT Iveco engine? I see them in farm tractors but I think they are used in a fair amount of industrial stuff. The heads on the Iveco look exactly like a 12 valve cummins head, I've used cummins gaskets on the Iveco and they match perfectly. The only difference is the Iveco has steam ports and uses a mls headgasket. I can't remeber the injector placement, if they are offset or not. I'm going to check that out next time i have a head off one one.
If I remember right the Iveco Cummins is a rear gear engine, has the same bore as a 5.9, but the stroke is something ridiculously big. The head and many things interchange, but the block and bottom end is quite a bit different
As I recall the really wide bowl in say an 05, pistons would tend to have issues seizing when making big power & why they went back to the narrower design bowls? Do you have a dyno to test your builds, know Rob planned on getting one but hasn't got there yet as far as we know. Very interesting build! The larger bore I would think would require more fuel than the sb CR, wouldn't it be even more efficient to run a sb vs bb?
Hi how reliable is a decked block I have mine decked as well going to use QSB 6.7 pistons and VP rods
for mine I just cut the front 4 bolt holes off of the front of the pan and welded a flat piece of steel to the pan and drilled the bolt holes. I tried 12v rods but with the stage 5 colt cam the rods were too close for comfort to the lobes. went with waglers. your budget turned out to be way cheaper than mine. after you get so deep into it you almost can't stop. make sure to post a running video.
Damn, that’s not a bad idea! I have 2 more to build after this one so maybe I’ll try that next time!
Waglers would be nice to have ugh! I’ve been eyeballing the carillo hybrid kit for a couple years
He means .003-.004” back lash on the gears
I honestly didn’t even think to check back lash… this is a good thing to note for the next build haha! I just did a “feels good enough” lol
Awesome build! I hope those stock 12 rods don't foul up the potential of this engine.
Ive seen as high as 1300hp on factory 12v rods that have been shot peened and fitted with ARP bolts. The most I expect out of this build is 800-1000hp, but I may also build it more for drivability than all out power too.
I just released the next part in the video series, go check er out!
I don't know if I missed it. But is that a 5.9 block?
6.7 block and crank! Only the cylinder head is off a 5.9L
The German in me is screaming unt dowl in each and every hole ja do it now! ... Don't worry I shut him up and I'm listening to you
Where do you get your machining done?
Cutterup in Calgary Alberta
Deboss garage you guys need to hang out!
I've been told that I'm like the younger Deboss haha! I dont doubt we wont meet at one point or another!
So. I’m wanting to know. I don’t have time to watch this all. But this a 6.7 block with a 12v head or the other way around
6.7 block, 12v head and gearcase!
any updates on your build?
Got the truck running last week, the engine is working good and overall has been a success! I have lots of filming and editing to do but expect to see a part 2 here soon :)
👍👍has anyone out there ever tried running an Iveco NEF67 crankshaft in a b series? It's 5.2" stroke I believe,that would fit ...not sure on connecting rod length or anything... perhaps that would be foolish ... there's a " mile high" striker crank someone designed that was like 5.4"?... based off a B4.5 Cummins of the same stroke.. that engine was 12 or 24 valve head with 4.02 bore..not sure on connecting rod length.ill to look in the manual..but anyway 👍👍👊
I think Cutterup has one of the engines and had planned to try and fit it into a regular 6.7 or 5.9 block, but I have no idea about the scope of machine work required to fit that monster!
Are you going to polish those forged rods?
No they’re just staying as is, I have another set of shot peened rods with arp bolts for another 6.7 12v I’m building
How’s the build going?
Priority at the moment is on the nova and after that’s running and driving I’ll be shifting back to the 6.7
@@Hazardous-Hotrod-Knowledge looking forward to it
Power driven diesel can explaim any and all questions you have about piston bowel and etc
My cousin has talked to Will lots, they're great people over there
Doesn’t the p pump rob hp
I mean, it’s a less efficient system Vs the common rail injection system and it does take a lot more power to turn than a CP3 so you aren’t wrong
Can't you just bore a 12v 5.9 out to a 6.7
You could if you ran a aftermarket sleeve I believe, but I’m not familiar with the specifics of doing something like that
@@Hazardous-Hotrod-Knowledge
Yeh after thinking about it, it's probably way more involved... P-pumping the 6.7 would probably be a better way to go.
why not put a matching gear on the pump, so factory 6.7 parts work as repair for the other items
Could you elaborate more? Like running a 6.7 straight cut gear?
There’s way to much math in this video!!!😂😂😂
Don’t worry, part 2 for the video has 80% less math and 100% more engine noises 🤣
@@Hazardous-Hotrod-Knowledge nice can’t wait 👍
I've spent whole entire life offshore I'm going to tell you right now Cummins is the worst water you can have if you want long life in jeopardy you going to go cat are the old-time hero Volvo these diesels idle four years at time and just work in my history Cummins is like the Harbor Freight Tool tell me I'm wrong because nobody will
You are wrong
I've seen a 12 valve with 14,000+ hours without any engine work. My buddy has a 5.9 common rail with 600,000 miles on it with no engine work done to it. They were both stock engines. I think the 6.7 gets a lot of hate from people that think they can make 600hp without head studs or people that don't watch egts and burn them up.
I seen a 12 valve in a generator role on a ship with 59000 hours and it died because someone on the crew overheated it (something to do with not running water or some sort of negligence)
People can say good and bad things about all engines when you really start to scrutinize Cummins Vs CAT vs Volvo vs something else and it comes down to what someone prefers
Something I like about the Cummins in non automotive applications (equipment), is that I can go to local NAPA or on rockauto and find most of anything needed to fix it
