I keep coming back to your older videos. Just wanted to let you know you should be proud of yourself for sharing this information. A lot of us understand the time and effort put in to such information. I believe I speak for all the true car nerds on youtube by saying thank you and we appreciate your channel so much.

Those 4.2 engines are one of the best engines ever made. Very robust. That car is really nice.

I love all the unique builds this guy does

This channel is giving me hope to be able to restore my 81 fire chicken. Seeing the things your doing with these 4200s is inspiring, seeing these videos gives me a little bit of hope that I could maybe one day swap out that cracked 400 and do something nobody else is really doing 🤘🏻🤘🏻 thank you for being the trailblazer of this platform!

Trying to pick up a 91 300zx roller and have two buddies that are arguing with each other over LS vs 2J swaps. Imma piss both of em off and do a 4200 now 😂. Thanks for all the great info. I'm a big fan of Haltech ECUs so I may splurge there just so I have all the parameters I may want to play around with.

I have been looking for an engine swap on my 4runner. I considered Ls, 2jz, and even a Toyota 4.8L. but this right here has completely changed my mind. The barra craze is starting and trying to find one is Expensive ! Loving this swap.. Thanks man !

I currently have one sitting in an s197 mustang. It's just for mock up. Still gotta figure out which transmission I was use. And whether I wanna put the ITB on or just sell it and get a better intake. I'm glad u mentioned the pan because I had to remove the pan to get it to set in there. I'll probably make a video series, but it's goin on the back burner for a couple months. I also think a cowl hood will fix my clearance issue

2:05 LOVE how keeping the flat hood was a priority.

This is absolutely brilliant… such fine work. I have an 04 and 06 trailblazer I’m working and all the info is so appreciated.

Great video , looking to do a volvo 240 sleeper, inline 6, this are way cheaper than the 2jz , and still hold with stock equipment , I believe it would fit, thanks for your knowledge , great job

Thank you for another great video. The detailed information, especially the variable valve timing controlled by the MS, very cool.

NICE job brotha, keep the tech tips coming. Very appreciated it!

Great information! Thank you for sharing. You have a lot of R&D into this .

Excellent! Thank you. I found out about your video from the Facebook 4200 forum.

Those individual oil feed ports are amazing. I honestly didn't know that was a thing with the atlas engines!

Very Inspirational video. Thats cool that the oil system can be modified with little effort on these engines. Thanks for all the info shared👍

Selling my C6 Z06, and me and some buddies are possibly going to turbo one of these. Thanks for all the insight and knowledge on this platform sir!

The video we've all been waiting for

Love the build! Thanks for sharing the info.

Thank you so much for sharing. This is my next engine platform. Been using Mitsubishi to get into the 8-9s for awhile, and wanted to try something new. Again thank you especially for the oiling tips and bellhousing tips

After building a honda I don't ever want to touch a V engine. It really nice to see theres a highly available modern straight six capable of power

I’m really getting fired up about these engines. I’m building a Lotus 7 type car. 400 reliable hp would be insane and the straight 6 sound would be more inline with that era. Plus the sound!!!

More knowledge bombs from the man himself!

Great and fascinating detailed explanation. Enjoyed every minute. Thanks.

Awesome channel man, been following the stuff matt shares on sloppy that you guys build. Never know you had a youtube channel though!

Always with good stuff man

Love that ending, that thing sounds amazing.

Thank you for the inspiration I'm looking to do this on my 50 Chevy Deluxe.

aussie here i love this engine and the barra intecs

Great info!! Thank you.

cool video. good information

I'm in love with this Channel. Your attention to detail, and step by step instructions on what is going on, it's just second to none. You guys put all the meat on the plate, and say, just fuk the potatoes. that, my friend, is exactly what I'm looking for. It's more than I had hoped for, especially from a KZfaq channel. Just like your Dyno numbers, your videos are just getting better, and better. I'm a crackhead that has found my crack. Keep up the good work. Stay warm, guys. I can't wait for the next one....💯💯💯💯💯😎👍💯💯💯💯💯

Dam man you are a very smart man.I have a 2004 GMC envoy with the 4.2 l and it is the most gutless piece of crap I've ever driven in my life

best video ever!!!!!!!!!

Man you got some cool rides 😎 👌 👀 🔥 💯

I am so grateful for this Chanel! You speak of 1st Gen systems, and the downfalls of the stock ECU at 16 psi boost. Say I want to run 8 psi max. Say it’s my first vehicle that I have boosted and say my kids will occasionally drive it and I don’t want crazy I want fun. Can I run the first Gen ECU then?

Calvin, great idea on fitting the turbo! I am left wondering how you feed exhaust pressure to your waste gate?

I subscribed !!

My brother from another mother! The internet is a beautiful fucking thing!

Great video, Calvin! Appreciate you taking the time on top of everything else, to walk us through it. One point of clarification. While the 2002-2005 factory ECUs are very limited, the 2006 and 2007 P12 is setup for 2 bar out of the gate, including spark and fuel. The E67 used in 2008 and 2009 is even more flexible with scaleable axis on the timing tables. Still, neither will ever be as flexible as MS.

Great presentation! Oil filter is questionable with all you invested I would definitely upgrade, NAPA gold or Wix.

Just found this video and I love it. So creative! Just curious what did you do for a flex plate?

Thanks for the video. If you read your comments, I would love to see something covering what you are doing for adapting, what I assume to be, different transmissions ti the 4200 and it's different starter location.

Great automotive engineering. Great mechanics are so under rated. Too bad the video sound is so bad with the wind noise.

Calvin thank you so much for putting such a great informative video together! I have a question for you regarding using this family of engines for road racing application. You mentioned that the stock oil system needs to be upgraded and modified to keep the oil pressure up. How would these engines hold up with pulling some serious lateral Gs while going through corners?

Just quick questions I have earlier 02 will it handle build like this cool channel ima keep checking out the vids.

GM has a very tough version of the 4L60e for the Trailblazer SS and Corvette. You can buy the parts or have a shop upgrade the regular version or put race ready parts instead. That car really goes! My trailblazer won't go that fast but I'm past the point of wanting speed. I already got my ya yas for speed out yrs ago lol.

I’m gonna keep this video in mind for whenever I get around to swapping my firebird. You really know your shit about these engines. Only thing I’d do differently is I plan on going with an ecumaster stand-alone just so that I don’t run into those issues you were having with the ecu not being able to support certain hardware EDIT: with regards to the intake manifold, how’d you go about making the one for the stude? I remember you posting about a 3D printed runner setup that would allow you to run a generic plenum setup, but never saw anything else regarding it

I would like to see this engine in a pickup truck. I doubt I would need a shoehorn to make it fit. There is always an option of doing a body lift to obtain a few more inches of clearance. The trailblazers are being parted out left, and right. The internet has web pages full of electrical problems reported, and other fix-it solutions. I would sure like to have this engine in my 96 GMC.

I really like Sleepers

I have just a normal 04 Vortec 4200 engine yet this vid reveals some secrets to me. thanks. What do you think of "boron nitride" lubricant

My 61 falcon ranchero will be getting a 4.2 swap one day. Won’t be anytime soon but it’s going to happen

In the future, dead cat on microphone, and speaker should have a lapel mic. Should fix your wind noise. I want to use a 2006 4200 in my 2001 Sierra using a stock ECU and only 6psi of boost with the .48/.61 T3 turbo that I already have, but I'm hoping to use a 6L80 behind it. Is this possible, and do you have advice and/or information on where I should look for the intro I need to make such a build possible?

I wanna drop one of these in my 66 C10.

Thanks great video, lots of info , I have a question , did this 4200 or 4.2 came out without a turbo, love LS swaps but 4.2 sounds very interesting, thanks again

I have a 3SGE beams engine running on microsquirt and was tempted to try and use the pwm wire for vvti control. I wonder how wired it would be on that engine due to both intake and exhaust cam gears are adjustable. But either way thanks for this video! Great info and way simpler than I would have thought. I think I'm gonna find a 80's c10 to swap these motors into. Do you think a adapter plate used for bop to sbc would be a great starting point or are the dowled bolt holes off from atlas to sbc/ls?

The h3 hummer comes with a rear sump pan im pretty sure it was a 4200 but it could have been a 5cyl i put a trans atcase and diff in the one i worked on it doesnt have the diff through the pan like the trailblazers

You could do a video just on the oil pan build.

Have you looked into speeduino it’s still batch fire but you get 4 injector outputs and 4 ignition outputs and still uses tunner studio for the software and you can control Vvti with it and boost control. I really like this build and wanting to go the route you did oh and the speeduino is cheaper than the MicroSquirt assembled

If you have a lathe just make a allen plug to replace the fill cap

Awesome ride I'd like to do that to a something. I've always been an inline 6 fan,I think it was the Jeep 4.0 that did it for me. I like the chevy 250 inline 6 also. If I wanted keep the engine mainly stock but add 25 more hp,can it be achieved with the stock ecu? What would it need a chip or would I need to mod the ecu to advance the spark?

How are you running your accessory drive? I also want to remove my AC compressor.

Not knowing much about Microsquirts or even Megasquirts have you looked into some of the other aftermarket ecu's such as a Holley, Hal-tech I know that some of them will allow much more IO's and programability. Would love to see what you could do with one of these if you could control every aspect of the tune

Great info! Ever thought of trying the 5cyl? Or are they not as strong?

My brother just told me about these swaps being done. He pick up a 4 door nova with no engine said had I-6 factory think pit in a newer 4.2L

Killer setup and car! So Im curious why you went Microsquirt? I'm currently tuning the 08 4200 swap I did in my Boneville and the stock E67 ECU with an LSA 6.2 Maf sensor I'm already at 12 lbs of boost with no issues. Not hating your decision just curious. I come from the LS world, and keeping the factory VVT and knock sensors (I need to run 91 octane and have very limited access to E85 here) was big for me. And I'm not a pro tuner, so having the stock GM tables was helpful.

Aww yea! 4200 !

If you ran a better more capable ecu would you have better luck with the the various options you talked about struggling with controlling?

Do you have detentions of its current setup?

smart pop and son!! bitchin car and motor!

What is factory injector size and could you run bigger to run e85 on stock motor😊

Looking to swap this in a Mercedes 190e for a unique street build no real reason just like unique builds

Could you use a WOT switch to trigger the cam timing?

What injector can you put in 4.2

Someone need to do an all aluminum v12 based off this block and head.

my ideal candidate for one of these is like a 75 Monte Carlo with those giant long noses.

Forgive me if I missed it but I'm a GMC owner that has a 4200 vortec and I know that the standard oil capacity with the regular pan is 7 quarts could you tell me how many quarts you can hold once you switch to the Colorado pin?

Cliff notes; '06-up engine, aftermarket ecu, custom oil pan, feed main #5. Did you guys use the special balancer on this engine? The manufacture name escapes me...

It would be nice if hptuners could do a OS change on the factory ecu

Someone [who has the talent; not me!] needs to do a trans adapter to give the Atlas ["Why you keep calling Atlas 'Vortec' Quimosabe?"] the Slant-6 treatment, which would at least address some of the engine height issue...

How do I go about getting a aftermarket ECU just trying to get some power out of this

Hey, what do you use to tune these? I have a supercharged one I’d love to get running. Thanks!!

And the Ford Fairlane

Hood scoop? A nice hood cowl would have been cool.

Does the 4.2 OE torque converter mate up with the TH400 utilizing the EM Tech torque converter adapter and bell housing adapter? Also, would a junk yard T400 work fine with a stock 4.2? Thanks again

Would this engine be a good swap for a 1 ton pickup truck that came stock with a 454 v8?

How is there not more aftermarket for this engine? Cams, oil pans, even a piggyback ECU to simplify everything. Anyone just did a turbo on the 5-cylinder?

So what do I need to do to fit one of these into my 02' Silverado?

What’s the drawback of using an unlocked stock ecu over going to mega squirt

How would I be able to get ahold of you if I had any questions? I'm looking to swap one into my 04 1500 silverado

For those who like the Ford looks but chevy power. I'm curious.... why not on a chevy classic?

What if I did a 4200 swap in my 1993 Chevy s10 ext cab?

I know this is an old video, but what was the motivation of putting this engine in that particular car? Just curious if you are still reading comments.

do you know how much the emtech adapter plate is? I hate when companies don't list their pricing on the website.

Do y’all think it could be possible to be done in a third gen camaro?

Hey for the ls1 throttle body did you have to do any modifications for the install just wondering? Any info would help and much appreciated

What did you do about the torque converter?

Wanna build my car like this for me?

What kind of k member do you have? Is it like a upr with ls mounts?

How much power have you consistently achieved out of a turbocharged Vortec 4200? I was thinking about building a street/strip car using this engine.
