I would love to see you guys offer new 5.9 12v long blocks or complete create engines. Definitely interested in that.

[@bernhard8540]

Pretty sure you can use the D&J short block..? It would be an upgrade compared to the old 5.9 blocks also because the commonrail block gets rid of the thin block early cummin's issues 😀 don't quote me but the block should work, you will have to use the 12v pistons though i think :) happy building ❤️

[@N.A.J.]

Whatever happened with the UCC engine from Todd's truck? No failure analysis or update on what is planned next after the big explosion. Good collaboration of parts and team effort in this video.

[@1276Tim]

You know it's a good day when there are two uploads, one from Josh and one on here from both of you together 👌👌👌

[@jamesmarlar696]

I just absolutly love how relaxed and down to earth you guys are.

[@mikestrucks]

Awesome video guys 👍🏻 can’t wait to see the race !!

[@coalstang]

love the vids boys. just cool to hear specs and opinions. really appreciate it. keep up the great work. 👍👍

[@deadlift4life1]

Really curious to see what Todd will end up putting as atmosferic charger/s?

[@bdjm8595]

Great breakdown guys, thanks a lot!!!

[@jeffbeaird747]

Love it..! I’m excited to see what’s next..!

[@kylegodderidge2049]

Love these kind of videos! Keep it up

[@bernhard8540]

One thing I love about my 04 haha no emissions crap in the way of hp haha just had to swap an 06 ecm in it and some wiring and I can now use efi with switch on the fly tuning 😀 that's the one downfall to the 03-04 ram trucks is you can't use a 5 position tune of the fly switch 😞

[@colinlawrence2186]

Great video guys really good to compare the two engine specs back to back i can't wait for the dyno sessions and possibly a little street time to check out there street manners God bless stay safe and good luck 🙋‍♂️🇬🇧

[@jeremiahmoss6015]

Did you guys post on all the results of the comps that you used the motors on?

[@tonyhawk8461]

I love every video you guys put out. 🙃

[@turbodieselgarage]

Good luck to you both from Canada EH!!

[@73cjproject]

Really awesome to see how the experience you both have had gone into these builds. Cool to see the difference between a solid build for a tow/street set up versus a more aggressive street/ripper type truck. But I know Josh will still hook the gooseneck up to the 07 if needed.

[@biggemaehlich]

Where’s the rest of the the videos? I want to see the event and results.

[@jesserasso1042]

A thanks Josh for the shop tour I happy you your a really good dude and all the crew you guy deserve a 100⭐ ratting I highly recommend your shop to everyone thanks for getting my block done tell Phil/Felipe he's a very good dude to I wanna see him more in the video thanks again bro looking forward to you guys running my truck when it gets done thanks again

[@RadDadisRad]

I love these Cummins builds.

[@MrShanegoldman]

Enjoy the videos, what cams are you running?

[@bernhard8540]

The issue with the 14mm pump is the modded regulator it causes surges but if you use a stock cummins one in the 14mm pump it gets rid of the surge

[@MAC_6.7]

Was that picnic awning you guys were working on slinging a head out under? Lol

[@jimmungai1938]

Hey I was thinking a while back Todd you were talking about Val Springs in one of your tutorials and a real heavy valve spring high-pressure spring is hard on the block I got to thinking why not you can put cambering bushings all through the air all the way down why not do diamond light coating on the cam bushings and on the journal of the cams I think that would help this is six in a row jim from Kennerdell Pennsylvania

[@MQuinn-si4tp]

You've been talking about piston bowl shape vs. Power on fuel only, what are the power digits between a wide flat bowl vs a narrow deep bowl? We're doing tractor pulling and all we care about is power, nothing else. Thanks for answering, great content, take care, Greetings from Germany!

[@HunterRoenfeldt]

You referenced a podcast. What podcast do you like to listen to for the diesel performance stuff

[@jimkillen1065]

I enjoy watching these videos . When you call there shop they always answered my questions and very helpful . I really like the way they build there automatic with the modifications to make them live

[@ryanstafford6874]

How well would the total seal rings hold up on the street. In a mild build/ tow setup.

[@bcbloc02]

So when Todd said aftermarket 6.7 block is that a Hamilton or a China?

[@timothymroberts2949]

I would love to buy a copy of your engine Todd!

[@jaythacker5160]

Hey yall use P or H bearings? Would you use the same clearances for both or not. thx

[@garycraig4277]

Soooo is The Godfather coming back? I love your videos I’m trying to figure out what I want to do to my 2012 6.7

[@bagged1998]

What is the difference in the 6.7 rail and 5.9 rail?

[@chucktraughber505]

I've replaced tons on #4 fuel lines on 5.9's

[@alexpigusch7954]

What are y’all running for camshafts?

[@jeremiahmoss6015]

What podcasts do you guys recommend?

[@titanfab3816]

Josh rocking those cody James work boots

[@kylegodderidge2049]

What cams are in each engine, 188/220s?

[@michaeltrue1143]

I will be a test guinea pig for one of your cylinder heads lol it will take a beating daily.

[@steveleach6641]

New engine baring tool? Nice tease… Why not extend flange sleeves above the block and into the head to eliminate the fire ring? Would that even work?

[@michaellawrence3796]

Whats the difference of a sleaved 6.7 to a 6.4 and a decranked 6.7 to a 6.4

[@jimmungai1938]

Is there any chance that a guy could get the diamond light coating on the bearing surfaces in the or I should say were the camera aids in the block and then the cam journals itself why couldn’t you do that anyhow that would help your make your block last longer because you’re running pretty high spring pressure I would help this is six in a row jim again

[@evelandjd5111]

If clientele agree to distribute video of your work and builds on their vehicles I would appreciate the content. “Builds for Clients.”

[@TheProchargedmopar]

👍💪

[@jimmungai1938]

I wish a guy could get the second ring as a step ring you don’t have an a gap all right I mean you still have your end clearance but one ring one into the ring steps over the other that really helps with blow by and it makes your engine more efficient goddamn if we could just get people to start making them Charlton Albert well now Ackerly and Albert he just won’t make them and I don’t know if his partners run out and probably has I would imagine someone else can start making them anyway this is six and a row jim I’m trying to build my engine get it as much horsepower as I can without adding lots of fuel trying to do it through efficiency and deathly gonna do an upgrade on my HX 35 and anyways I wanna put a butter turbo on there I already have a 4 inch exhaust I don’t have a 4 inch downpipe that’s next anyway hey you guys do good you’re really good for the industry and I like the idea that you try to keep them clean OK have a good day be safe out there guys

[@Sdukes001]

Good luck guys I think PDD goes 1-2

[@frediefarmer]

👍🏽👍🏽

[@M-FE]

I wish that I didn't have a g56 in my 06 3500 ram now :(

[@M-FE]

@Cam I didn't buy a manual transmission diesel truck to drag race, I'm just sad because I know that with a g56 I'm fairly limited to the amount of power I can throw at it .

[@AnonYmous-kd9el]

I want to see another grandpa truck gone wild

[@bladenrexroth2555]

I want to see one of your engines reach 1 million miles towing 45k#'s

[@chevyon37s]

....so you want to see them drop a 6.7L in a semi truck?

[@bandabanderos]

Drew w ignore Blasen, he’s the kinda guy that thinks the government should make having fun illegal.

[@bcbloc02]

That is the world of 11liter plus engines. No light duty diesel or pickup is going to do that.

[@bert5003]

you guys playing with water meth at all?

[@BigGroupHug]

Could y'all talk any slower?
