I wouldnt be surprised if it made 850+ on the tire spin hit. It sounded like it was making way more steam than any other run. I still have zero doubts you guys will beak 950 or even 1k with this platform. Awesome video!!
"Oopsie" is always a good word to remember in times like these! And then there's "induced voltage". Those are good words too... Who knew that stock rods would last to 800+ hp? Good job finding the limits!
Iridium and small electrodes are not your enemies but rather your allies, look somewhere else for your foes(heat range, electrode gap and ignition system "strength").

Wow, Six in a row sure can go! Sorry to see this particular engine break a rod, but, as you have pointed out, these engines are inexpensive in the wrecking yards.

@@Calvin-Nelson That's why I like your stuff. You are finding the inexpensive way to go fast. Much more interesting than spending cubic dollars. Whichever way you go, I'm hooked.
I found your channel by accident. I have owned a 2006 Trailblazer from the time it rolled out of the showroom. At this point I am keeping it and have considered making a project of it. Your videos have helped clear the air as to what is possible with this platform. Thank you.
Nice job, better you than me blowing mine up to push to the limits! That basically means stock bottom end took 1000 hp, which has been the number floating around….and about 3-4 times the stock power output!
After finding this channel I've been obsessed with researching these engines and come to the conclusion My 81 Zephyr is getting one and the ls is coming out!
So you finally found the limit of the bottom end after all that abuse. Wow. All your real money still sits there waiting on another $250 donor engine. Way to go out with a bang Calvin. Can't wait for the autopsy and the next 4200 engine series.
That should have thrown red flags but.. we wanted to max the turbo out so we went for more boost. Bang away. You don't know limits until you exceed them.
Thank you for having the guts to push it that hard. That's the only way to learn the limits, and I am pretty sure you never even really reached it. Maybe some ring gap, a little more fuel with the added timing, and you will hit 1000whp.
That is just AMAZING! 800+ horsepower at the WHEELS with 4.2L of six cylinder power. Would have loved to see the numbers at the crank. Those rods put up with some serious power per cylinder before letting go.
its amazing if you think about it the variable cam timing make such a long torque curve got a big long twisty crank a long stroke and making 800 hp with 250 cubic inches !!! thats crazy
Like I always tell Holdner, if you chrome plate the cam cover (aluminum is plateble) or in the case of a carb, the air cleaner, you can gain at least 50hp (lol). Holdner doesn't believe me but when you consider it reflects Lazer rays, gamma rays, and other rays from outer space (maybe the cause of spark breakup), it's worth a try, even though the red looks good. Great video, I love following the developement of this "truck" engine.
Outside our family and those involved, Richard was one of the first to hear the news. He is an inspiration for us and many others. We truly appreciate all he has done and will do in the future.
Can you do a turbo build series on the LS/LT based 4.3L V6 (LV3) from a 2013+ Silverado/ Sierra? I think it would be cool as shit to swap it into a G body or S10/ Blazer in the spirit of the Grand National and Syclone/ Typhoon. Too many people are LS swapping those vehicles unaware that GM makes a V6 with LS/LT architecture that they can boost.
When the bearing is perfectly fine, that indicates the WRIST PIN likely started binding in the piston. If that doesn't shatter the piston (either split in 2 or crack off a skirt), it usually bends/breaks the rod. All because the piston can't rotate on the small end, but the crank keeps moving the big end. Bend, snap, boom.
You think it's most likely that the pin binding in the piston STARTED the problems, or a slight compression/bend of the rod misaligned the pin in the piston relative to the cylinder bore, which STARTED the trouble?
@@tptrsn It's the binding that starts the failure. GM has fairly large gaps either side of the rod's small end to make it worse. If the rod was buckling, it would fold in the weakest direction. I think the most simple way to picture it is to smash the handle of a hammer into a concrete block. The head's momentum is going to rip the handle in 2. Check out the Cleetus Mcfarland channel where they tear down their built engine after it took 61psi: the heavy duty pins didn't flex/bind so the rods bent sideways (weakest direction, 90deg from thrust). Then look at most factory LS rods that bend - they bend in-line with thrust/rotation instead.
So much potential in this platform a built bottom end or maybe someday even a billet block the sky’s the limit I see 1k hp in the near future! keep up the great work!
Cant wait to see what you guys can do with a new rods and piston combo and maybe a ported head Great work Men ! And a great sent off to your ( little soldier)
Nice job nivlac... that is amazing what that " little engine that could"" went threw before throwing the white flag. That recap at the end made the video for me. Thx for taking us for the ride.
@@Calvin-Nelson I meant what will be the ur guess on the next weekest link. Assuming better rods/pistons and some head studs since ull have the head off what would the best weakest since u found rhe limit on a stock one....
On a stock bottom end!? I never would have thought it would have been able to see that much boost/power with stock rods! I have the 5 cylinder, I love it and considered boosting it but got an Audi instead. Lol
It’s a testament to how well these are built. I’d say the factory vehicle would wear out well before a maintained 4200 i6 that’s some serious HP over stock.
Stock 05 trailblazer with a almost non existent matenince and constant abuse had transmission fail before the engine (will replace transmission to get it going again)
love to see your own "limited edition" 1978-1980 Buick Century Coupes with tuned 600hp atw 4200, better brakes, suspension and handling, 5 speed and LS. Would sell out.
For sure. The 7875 ripped. I honestly think all it had to give was ~31. I kept trying to give it boost duty at only 6000 and above and the boost just wouldn't go up.
Once watched and engine build with boost. Finally it was dialed in pretty much and there came a time that they wanted to throw more boost at it. Didn't make appropriate hp. In the end, when switching to iridium plugs they got the appropriate gains.. There conclusion was that the boost was snuffing the spark!!
Do you know the back pressure on the exhaust side? Have a liltle hunch that the turbo was close to maxing out on that setup. Damn impressive numbers for a stock bottom end!
Man you got me convinced with the vortec 4200 I’ve always had and interest on them since they are relatively everywhere and best part dirt cheap but never got to see many or any videos or forums on how much potential they have,and thanks to you we all now it is worthy of a performance engine even in stock form,on the other hand I had an idea on mounting this engine on a 90’s bmw mostly a e36 with a 6 speed manual put a turbo on it and do like a budget drift car but my main concern is how big it is and what 6 speed would be good to mount the engine too so it can handle the power.great info and videos I just got subscribed 👍🏻
Hey nivlac57, I have a 08 3.7 I5. I love what your doing. I wish you could do some 3.7 i5 mods. I still haven't seen any atlas engine with all forged parts and have forced induction. I found forged connecting rods for really good prices when searching on google for performance parts.
Yeah. The 5 cylinders are a little attractive to me, but it would have to be into a chassis that we just absolutely could not squeeze a 4200 into. Well see what the future holds.
A piston and rod setup i think would easily handle making over 1000hp, and i feel like a self racing style build with sleeves etc.. should be good for 1400+, theres a reason that engine out of the nova wagon that self racing built has lasted for 12+ years at 1000hp+, thats also without aluminum rods and newer piston tech, this platform is looking very promising.
Love to see all of this. Looking to do one in my 55’ 1st Chevy 1.5ton. I’d love to see details about each build in comments, such as year of engine, ecu, basic boost and whp etc. imma have to tap your brain
Sounds like a good time. I honestly hadn't heard of it til just now. That will be right after drag week. Not sure I will have the vacation time to pull that one off unfortunately
Man, when I drove one of these in a LWB Trailblazer, my thoughts were always "a great engine that needs at least two more gears". I doubt I'd have that concern with this monster.
So now that you have the formula figured out for 800+ RWHP, how long do you think a less beat on 4200 can last at that HP level? Are there any options out there for a more stout bottom end?
I don't think it would last very long, but I could be wrong. Thats almost 4hp/ci. Thats pretty amazing for a stock rod and piston. Yes, there are options for built bottom ends. Stay tuned.
Absolutely badass! 3 questions: 1) Do you think it was the timing you added that finally did in that rod? 2) What turbo is this again? 3) Did you show the dyno curves? I'd like to see if this thing could be biased more away from making torque..
1)I think so, but may have been the 40 psi boost it saw for a brief moment. 2)Ebay 7875 with a VS racing custom fit compressor wheel. Lol 3) I didn't show the graphs. Unfortunately, the RPM probe was giving us fits so I don't have any torque values.
@@Calvin-Nelson Interesting stuff, thanks!! So this eBay 7875 isn't one of the ones that come with the billet wheel already, or it is, but you tried a different billet wheel from Viren that you "custom fit" in it? (Nice work on that, BTW! I was curious if that wheel was going to be balanced well enough to work after that, and obviously it was.)
Good grief..! I'm looking forward to seeing what the power limit is on a "trustworthy" SBE setup. Could it be that you can get more reliable power out of a 4200 than a 4.8? I think the standard Sloppy 4.8 setup is something like 550-600?
I doubt it, cause the HP per cylinder is alot favorable for the 4.8, cause its an 8 cylinder vs the 6 cylinder. Still when compared to other great 6 cylinders like the barra, 2jz/1jz, RB this is right up there with the best of them.
@@thewraith6360 Most inline motors carry the advantage of more main bearings per cylinder versus their V counterparts, the 4200 is over-head cam, and is 4v/cylinder. Without knowing rod and main sizes and all of that.... At a glance the 4200 is better at everything. So far, it appears the testing is showing that too. I'm not sure how many Sloppy 4.8 setups got this far. I think 700hp was where Matt stopped with them? I'm not intending to put the two builders against each other. I'm more thinking about what you can get for the dead _cheapest_ amount of money. Even the lowly 4.8s are starting to get more expensive. I don't know what the 4200 market is like, but I would suspect cheaper?
@@TheBrokenLife 4.8s have made over 1300 SBE. Extra main bearings and main sizes isn't really ever an issue with the SBE stuff and thats more so an oiling or RPM issue then power taking capability issue, its usually piston issues or rod problems. For the sake of argument lets say the 4200 has rods and pistons that are just as strong as a 4.8, the 4.8s advantage is that it has 2 extra cylinders meaning the 6 cylinder would have to deal with more HP per cylinder than a v8 would. That is how all the major aftermarket companies rate their products HP per cylinder. 1200 hp on a v8 is less stress on the internals then 1200hp on a 6cylinder. Hence why calvin says this is the equivalant to 1100hp on a v8. Also 4v or 2v head doesn't matter, internal strength is the main concern when talking about SBE stuff.
Gone but not forgotten. This engine's sacrifice in the name of science will pave the way for many 4200's to come. o7

I was curious if that wheel was going to be balanced well enough to work after that, and obviously it was.)
@@tptrsn I've done that same method in the past on some gt3582s. I had reasonable confidence it would be fine.
Great job Calvin! what ECU are you using on that? How much dwell are you running on the stock coils? How much on the Race coils?
It has a megasquirt goldbox. The stock coils I gave 4ms. The race coils I gave 3ms for most of the pulls. For the last couple I gave them 4.5ms
@@Calvin-Nelson we got rained out on the 13th so we haven't tested Leo Santucci's car yet.
@@LANDISPERFORMANCE darn. I was going to ask, but figured something like that must have happened.
Love the content , thank you
You're welcome. Thank you for watching
awww man. what was oil pressure showing you? Awsome infor though. Good luck for your next one
80 psi
@@Calvin-Nelson before it chucked the rod? usualy it would drop a bit first
Hooray
That shit will buff out
Good grief..! I'm looking forward to seeing what the power limit is on a "trustworthy" SBE setup. Could it be that you can get more reliable power out of a 4200 than a 4.8? I think the standard Sloppy 4.8 setup is something like 550-600?
I doubt it, cause the HP per cylinder is alot favorable for the 4.8, cause its an 8 cylinder vs the 6 cylinder. Still when compared to other great 6 cylinders like the barra, 2jz/1jz, RB this is right up there with the best of them.
@@thewraith6360 Most inline motors carry the advantage of more main bearings per cylinder versus their V counterparts, the 4200 is over-head cam, and is 4v/cylinder.
Without knowing rod and main sizes and all of that.... At a glance the 4200 is better at everything. So far, it appears the testing is showing that too. I'm not sure how many Sloppy 4.8 setups got this far. I think 700hp was where Matt stopped with them?
I'm not intending to put the two builders against each other. I'm more thinking about what you can get for the dead _cheapest_ amount of money. Even the lowly 4.8s are starting to get more expensive. I don't know what the 4200 market is like, but I would suspect cheaper?
@@TheBrokenLife 4.8s have made over 1300 SBE. Extra main bearings and main sizes isn't really ever an issue with the SBE stuff and thats more so an oiling or RPM issue then power taking capability issue, its usually piston issues or rod problems. For the sake of argument lets say the 4200 has rods and pistons that are just as strong as a 4.8, the 4.8s advantage is that it has 2 extra cylinders meaning the 6 cylinder would have to deal with more HP per cylinder than a v8 would. That is how all the major aftermarket companies rate their products HP per cylinder. 1200 hp on a v8 is less stress on the internals then 1200hp on a 6cylinder. Hence why calvin says this is the equivalant to 1100hp on a v8. Also 4v or 2v head doesn't matter, internal strength is the main concern when talking about SBE stuff.
Curious to see autopsy.
Lack of ring gap probably?
Piston or rod.
Doubt it, but it's possible.
The king has fallen :( on to the next one lol
What transmission are you guys running on builds like these to handle that power?
TH400
I love your channel, due to being a I6 guy myself. Did you open up the ring gap on this engine? If so, how much?
Thanks. No we did not. It was 175k miles engine so we hoped it would be naturally ring gapped
@Nivlac57 I see you run mega squirt, do you know if holley terminator/ dominator can control this engine properly? (VCT/VVT)
@@timothydurm4366 they cannot.
Nice man that thing was cooking bet it would have done a 1000
I wish someone would come out with a T56 bellhousing adapter for these engines
They make adapters to go to SBC pattern.
Nice numbers. What spark plug gap on those plugs?
Honestly I never checked them. They looked to be about 0.020-0.025 just by the eyeball micrometer. Lol
@@Calvin-Nelson I think they are .030
Motor could have held 799hp forever.
For science!! 🤣
I know i comment alot on your videos calvin but did this have the BHJ dampener and what RPM were you spinning it to?
It's all good. I appreciate your comments. It had the BHJ damper. We were spinning it to 7100. Have had them to 7500 with the damper in the past.
That had stock ring gap right?
It did. Could have been the cause of death. We will find out in the autopsy
