I’ve grown to love these videos so much and look forward to these videos.
Love your work! Don't ever apologize for asking a stupid question. There is always someone else who is interested in the answer.
A few years from now: "My daughter building her first car"
Should keep the current motor and build it with her for a first car
And over clocking the onboard computer.
Jay this is not boring. Me and my buddy Mike back early 90 s built a LS7 in a 72 Camaro. The first time we fired it up with the open headers it shook the whole Garage.. brings back some good memories.
Jay: You wouldn't use these bearings in a race engine.
Me: Actually...
Jay: Nevermind
Jay: "I hate the smell of raw un-burnt fuel."
Me: Wait you run pump gas?!?!
Jay: "I'm probably too stupid to do carb tuning."
Me: "I'm probably too bad with computers to do EFI tuning on my car."
Everyone is too stupid for carb setup, its not really a science more trial and adjust. Sequential EFI with lambda control takes alot of the guesswork out of the equation. Plus computer people get to talk about waveforms, duty cycles and use computers to play withh graphs :)
@@AutomotiveAddiction "its not really a science more trial and adjust." -- Common misconception here. Science is not modeling, modeling is the result of science that helps you try to predict things, but has limitations in virtually every application. Due to differences engine to engine however, even the EFI is using feedback so you can tune. Not every engine responds the same way to the same inputs. It's really just the same process, different set of devices and tools for configuring it.
In fact, this is what science is precisely. The process is: Question -> Hypothesis -> Experiment -> Analysis -> Observation -> Repeat. So, your hypothesis might be that your engine is running lean, so you change jet sizes, you test it again and see if the issue has been corrected, etc, etc. Absolutely, that's science.
How to do that for EFI? Well, you're going to adjust code which will adjust your PWM duty cycle on the injectors, which will adjust your mixture instead. But since the input might not exactly produce a modeled/predicted air to fuel ratio, you read from an O2 sensor to determine what the mixture actually is, and then correct from there.
Some EFI systems will auto-tune for you, but they still use the same process, just less intervention.
Edit, P.S.: On MotorTrend there's a show called Engine Masters, they try things and then dyno test engines. They recently did an episode that involved a lot of carburetor tuning, and they went into detail on how they were adjusting the carb, changing jets, changing the secondary opening point, etc. You're really just adjusting the same parameters, but with physical hardware instead of software.
@@Sevalecan Theres quite alot wrong in what you've said there TBH... Carbs are open loop, Lambda controlled EFI is closed loop control system that has LTFT and STFT (long and short term fuel trims) Carbs have very little adjustment and tuning potential for so many reasons... not to mention it depends on how many 'barrels' to cylinders ratio lol... its not sequential injection... its inefficient and really not so much a science as being hit on the head with an apple.
So excited to see a video today. Thanks for asking questions and helping to educate all of us Jay.
It drives me crazy when I hear someone belittling someone else for asking a question. Everybody at some point had to ask a question about something to understand how it worked! Making fun of somebody for asking a questions doesn't make you look smart, it makes you look like an A-hole. Share the knowledge people!!
As a wise man once said... “the path to knowledge begins with three words: I don’t know.”
Rules to live by. Ask the dumb questions to avoid stupid mistakes.
P
the sign of a smart person is one who can say they don't know and then go find the answer. Another one is that they see something new or something they aren't 100% on and ask about it.
This is really cool content. Most of us drive cars and you don't get to see what goes into an engine and its nice to see it before its covered in oil.
So you’re telling me that I have been watching JayzTwoCents for almost a year now as a car junkie and I just now stumbled on Jay’s car channel?
Whelp.
I watch you for the computer content, and knew you had toys, but never knew how much a gearhead you were. Hell yeah!
I learned a lot today too. I may forget stuff easily but that's what the favourites lists are for.
This was very cool. Learned a lot! Thanks for taking us along!
Great video, cant wait to follow the progress
I’m an accountant that grew up building cars and computers with my dad. I really appreciate Jayz thirst for knowledge in the automotive world, you can tell he knows quite a bit but is also learning at the same time which is awesome, bravo 👏!
Such a beautiful piece of machining.
great video Jay, Iove the perspective. We all want to know more and you are asking all the right questions. SOMETIMES LOL. Looking forward to the rest of the build. I hope to do the same one day.
Really glad you decided to do EFI. Holley is a great system.
All engines are motors, not all motors are engines.
Real interesting stuff.
Can't wait for more engine building.
I love how low key and calm Mike always seem.. Seems like the type of guy I would have rebuild an engine for me 😊
Just built my wife's 96 Cherokee engine a few weeks ago, it was really fun. Enjoy the rest of your build.
Compared to your tech channel, it's really cool seeing you learn about something you've never really delved into a bunch.
You can do boost on a aluminum block without much of a problem if you get stronger sleeves. Cleetus Mcfarland ran Leroy with twin turbos on a aluminum block for a long time
Always good to ask questions and learn more. I've learned alot from Motor Trend's Engine master's as well. Really can't recommend it enough. I'll likely be putting in a 5.3 LS to replace the 4.0L I6 in my Jeep Comanche. Don't need big power, 350-400 is enough when the truck weighs just shy of 3,000lbs. Yank out all the horrible vacuum lines and get a simple harness from Holley. 80's EFI wasn't great.
Ended up on this channel because was researching my latest gaming rig and also being a car guy this is great. Thank you, magical TH-cam pixies for showing me this. Subbed.
If you can precisely overclock a CPU or GPU to its peak performance, you can tune a carburetor.
EFI is still better though, even if it's more difficult to set up initially. You get more power and better fuel economy at the same time, which is worth it if you ask me.
@@wowdogeful I wholeheartedly agree. I was only pointing out that Jay definitely has the skills to patiently test and tune a carburetor to get his desired performance out if it.
As well as better overall drivability.
@@wowdogeful a properly tuned carb will make more power, and noone cares about fuel economy in practice of power.
@@Joebauers2505 more power than fuel injected? That doesn't make any sense.
Any carb uses some sort of protrusion into the flow path to atomize the fuel(venturi). Fuel injected has no protrusion because its sprayed under pressure and can be placed anywhere in the inlet. Not only that but carbs are big and can soak up heat where they have to be mounted.
Wow Jay is sooooo out of his realm.
There's something incredibly fascinating about an engine going together :)
Came from your tech channel but im a hood tech at my local lube shop. Glad to find even more content that keeps me entertained
I agree its "simple" technology, but you really appreciate the 100+ years of fine tuning when you start hearing about bolt order and tolerances and how everything is honed to an exact science. So fascinating
I have only ever heard engine mount and engine oil, but I still think an engine is a motor so I'm with you.
7:25 - "I always like to see it because its just so freaking big". Thats what she said!
And it goes with the heads too
"well ill be dipped" i really hope that was a VGG reference
I’m excited to hear this thing 😁 can’t wait to get my Supra build started
you are the best dual niche ever
I fucking love you Jay. Theres such a huge overlap in our areas of interests as well as our sense of humor. Wish you all the best over there in the united states of freedom
Those Holley EFI systems make everything so much easier. Their premade harnesses save you so many headaches and they just flat out work. Great choice Jay!
@Austin M Yes
w8 this guy is not only tech guy i like this channel more and more i watch it
I'm so ready!!!!!!
Dang Frankenstein ported heads, quality stuff Jay!!
I am now officially caught up on Jay's new car and get more jealous every time I see it!
Jay, i never thought you were a car guy!!
Didn't know this dude was into cars that's pretty cool.
I've got no idea half the stuff ya said but I'll stick to something simple....
Hmmmm shiny parts 😘
As always great vid dude 👍
Back in high school, I took small engine repair my freshman (95-96) and sophomore (96-97) years, and planned on going further into auto mechanics/auto body then get into that as a career but... scheduling conflicts. Always wonder how different things would be if I had. But man, watching this brought back a lot of memories lol
Oh my god this is sick
Jay besides being a reason i switched to pc gaming you are also the reason i decided to buy a older corvette and own a car i have dreamed of owning. also these videos are giving me all kinds of ideas for it now.
The Holley Terminator X kit is epic! It can handle all the engine types, inductions, etc. I would build an LS with one. I plan on it, a 6.0 build and eventually boost that baby.
My guess that is the scat crank not fully made in the US. Still a great crankshaft!
I would highly suggest going through the Holley training on their efi stuff. I have finished 2 out of the 3 courses and loved every minute. Unless they have changed, you can take care of it all in a single week and get to check out the awesome corvette museum at the same time.
I am new to your computer channel and BRAND new to your car channel! glad I found both
Wow after looking you up for computer advice 6 years ago, you're doing cars just as I'm getting interested in them
nice engin have nice sound
An example of why you use the correct weight oil: One of the farms near me bought a brand new '16 Silverado 1500 with the Ecotec3 5.3 in it (direct injection, variable valve timing, etc). That engine calls for like 0w40 or 5w40 oil (forget which, exactly). They keep drums of 15w40 in the shop for tractors and big trucks. The guy who ran the shop told them to get the right weight oil for it, they ordered him to just use 15w40 oil. Cooked the engine by 12k miles, and GM wouldn't cover it under warranty. The truck wasn't even a year old.
it’s coming along👌🏁
Torque to Yield or Torque angle yield (further called TAY) bolts can be smaller for the same application because as it was told to me, "Some Japanese Math Wiz went to Honda and saw the really big bolts they use to use on cars and said, I can do that with a bolt half that size and it hold with more force." The reason that happens is that when you Torque a bolt just right and to the exact point where it starts to stretch it holds way more force than it would normally and is the strongest it will ever be. This is also why when you are working on your vehicle it's important to know if a bolt is TAY because you MUST (I can't emphasise this enough) make sure to replace any TAY bolts because the old bolts are stretched and will snap and break and cause serious damage or ( in cases such as suspension bolts) kill you.
Love the VGG reference at 17:55 #VGG
When dad ran A/ED back some years ago there were "Total Seal Rings". Basically the top ring had a thin oil ring type that went under the top ring. Then the gap were opposite of each other to create a total seal. The engine was a 427 4 bolt main block that he had bought back years ago for 75.00. The good old days.
Literally understand nothing of car talk and it's not my preferred thing in any way, but the guy from RedBarnRacing (I forget the name) is the absolute chillest dude
Is that oem sized intake valves, they are massive! Would have been rad to hear more about some of the clearance specs. I am imagining 1 - 3 thou piston to wall clearance and similar for main and rod bearings. Curious about ring gap positioning and spec as well ..
High flow exhaust, black widow exhaust, exhaust tips. Your good.
To my knowledge interchill systems work off air con yes, but when you wide open throttle you shuts the air con off. It’s doesn’t rob you of power during pull. And most definitely good for street racing.
Jay, dude... you need to mark these videos NSFW. That motor is just pr0nographic!
That really grinds my gears
Nice video even for those with less experience in engines.
It is a nice video even for those who have built engines
@@scott2100 Indeed
Hey I just wanted to let you know you are not alone in having that realization about the offset cylinders in a v-type engine.
When I first started getting into mechanics I thought each piston had its own crank bearing it wasn't until later I realized while watching a tear down that the two opposite Pistons share the same crank bearing.
I have to agree with mike down the road Jay is going to get the itch to start drag racing and that ls7 is gonna get swapped real fast.
Obviously the 350 is your engine and you can do what ever you please with it but it would be a super cool giveaway!
I agree, my 67 C-10 is in need of an engine right now.
Jay: "Not many moving parts..."
Every EV driver: "yaaa... I have one moving part in my MOTOR"
:'D
guess they don't have AC?....or much of a steering system?...
@@MatthewAucutt No bearings, either
@@MatthewAucutt Well, those do in fact have absolutely nothing to do with the drivetrain in an EV, they have their own accessory drive that runs off the EV battery. An EV's motor isn't spinning at a stop light to power the AC, the accessories have an independent drive.
@@Rappoltt No reason why you can't build an electric motor with bushings, the efficiency loss pretty marginal in the big picture. Obviously the OEMs are optimizing for efficiency though.
Tesla drivers specifically are always such douches. Like the worst combo of BMW and Prius driver lol
E85 is a great choice Jay. It's got a higher octane rating and it can pull heat out of the intake charge.
Progress!!
Haha. Cool I didn't know you had another channel. Building a motor is very tedious and more if it's custom even more. It's still a good experience.
Nice cars. I have a 996turbo with a built engine and 18G twins. My dad has a 69 Camaro convertible.
Don't apologize for asking questions that's how you learn.
JAY - buy a product called "RACE GAS"(yea, the name, I know...) to keep with you for just in case you can't find E85. It's an actual race fuel concentrate(not a cheap junk "octane booster") that is added to pump gas to raise the octane up to anywhere from 102 octane to 112 octane.
BTW, good man, that Mike guy - I'm in the process of planning a stroker 460 Ford big block for my nephew's Fox body Mustang. 4.440" bore(stock truck block), 4.500" stroke Jon Kaase SR71 cylinder heads, 13:1 compression for E85/race gas. EASY 800HP @ a relaxed 7500RPM, with the potential for an easy 4-figures with very mild boost from a moderately sized turbo.
BIG BLOCK LYFE
Yay car content.
Funny story: bought a forged TSP 427 (14k long block) to replace my LS7 as I lost cylinder 7 to ring gap plus boost. They gave me a US forged crank because of covid (shipping problems). It was actually cheaper than the Chinese forging.
C6Z w/ Novi 1500 704 RWHP uncorrected on mustang dyno in 85 degrees. Now to tackle the IATs.
Your engine is so cute. Vroom!
Now Mike's engine... daaaaamn...
Your truck seems really loud. How do you like the exhaust now that you put miles on it? Idk if we got an update on it. Keep these great videos coming!
I hope Jay and cleetus does a colab.. Two of my favorite youtubers
I was hoping for a Texas Speed 427
@@lordcommander3224 He's got a 427, just missing the texas speed portion of it
I really appreciate that "Here in my garage" joke :'D
Finally!!
E85 for the win! Even non FI cars can benefit just kinda depends on the platform. The newer mustangs love E85
On a long enough timeline, everything will eventually get an LS. 🤣
Even in the UK i hope this to be the case. My Mr2 might be a tough one tho ;)
Automotive Addiction - I’ve seen it done! Good luck with your build!

Crying in 2jz
I'm so happy you ditched the carb idea. Because that's what you were going to do first iirc. EFI all the way
did you do any block or cylinder prep or just drop in pistons?
Hard question for you Jay. What you enjoy more... working on your own vehicles or working on your own pcs
Also, with EFI/Holley, you can time your injectors to somewhat tune the smell of unburnt fuel out.
RING GAP! Super important if you ever go with boost.
As a person who works in an engine machine shop, I see so many experts doing stuff that makes me cringe. I was a bit nervous about this video but to my surprise this is in my opinion the right way to assemble a motor.
Great parts, and obviously someone that knows what they are doing assembling it. Looking forward to the next video.
No assembly grease is a fail
FLCivic I’ve already forgot what they used for assembly line but we’ll see. Maybe they will prime it with a pressure primer
I had to look up what was meant by E85. I don't think you can even get that in the UK. I certainly have never seen it for sale at any petrol station.
Jay got some deep deep pockets for custom PCs and custom classic cars.🤔😩
I wish I had his pockets to more or less do the same. Hahaha!!🤣😂
Love the car content!! 👍🏾👍🏾
I'm just saying, dudes got a 67 Camaro... in restored condition, thats like a 60,000 dollar car. Plus hes putting a 20-25 thousand dollar motor in it, he's either KILLING IT with ad revenues or the patreon guys are getting screwed.
While I find his content entertaining on occasion, I suspect he is way overpaid.
So does the extra cylinder just get capped off if you're only using 7 pistons? Or does it just get left open but with no injection?
I'll be Dipped!!!! #VGG
at 15:47.. what ratchet is that in the middle in between the pistons? i want one
I'm not an engine person or know much about America's fuel at petrol stations. But is their E when it comes to fuel the same as our Ron in the UK? Cos we have 95 and 99 as standard fuels at the pumps
Are you running stock or 1/4 race cam ?
You should do a custom build based on this car. Like you ZL1 one raffled. Think old school plain black case and threadripper guts.
That E85 May Work In Cal But Not Here in My Little Hick Town ! I Thing The Closest Place around Here Is About 45Min To 1 Hour Drive B for ya can even think about finding it !
haha jay you'll annoy us brits as well, they're engines! love these videos tho really fun
Motor ;)
@@Dracossaint The one under the bonnet yea? ;)
