@16:58 you could tell how proud Uncle Bob was of that engine. You can tell that man takes pride in everything he does.
I see him showing pride in Billy, too. My son makes me smile like that when I see him enjoying something I love doing.
@@Carl_Jr We agree Carl,, @17:40 Bob kinda has his arm around Billy,, that's kinda like a 'term of endearment',, sorta like a Father/Son. Bob and Bill both are proud of where Billy's knowledge is right now. Tommy is coming along at at even faster pace. These two Hoskinson boys are bound for greatness in the racing world,, they just are. They've had awesome mentorship their entire lives and they've responded. It has been stated by many on this and the other SRC channels,, "Where will these boys be when they're in their mid to late 30's and beyond?". Time will tell but from all we see on these RUclips channels the Moon isn't to high a goal. Will they go Pro one day in say Pro Mod, Pro Stock or higher? I'm thinking it is a good possibility 'IF' that's something they want. Moving up to BIG TIRE something on the line of NPK?? I'm thinking Billy is already talking about going BIG TIRE with his Nova. We're enjoying being along for their trip no matter where they want to go. Thanks to all who have been a part of these young men's upbringing. We can't overlook how important Uncle Bucko, Miss Vikki, BIG Rob and Kenny Powers have been in their lives, no Sir,, we cannot ignore the importance these people have played in Billy and Tommy's lives.
I would love to hang out with Uncle Bob at his shop to watch him in action. I know talent and he’s got it
@@quickdeuce ppl
That engine is a joke over 8.000 rpm and won't even make 400 HP
I just loved seeing Uncle Bob’s excitement on that last pull when it hit 607 hp at 8200 RPM, then the props he gave you when you suggested a different cam degree.
Ya I could tell bob wanted to see where it would stop making power. Billy is an 8200 guy
Bob suggested the cam change. He kinda had to talk Billy into it lol.
@@Degenerate124 yeah he pulled the ole drop a couple suggestions and make them think it was there idea trick

Damn LS engines are great and everything but nothing sounds as good as a big cam high compression old school SBC. Nice job Billy. That trucks going to fly.
Have you heard the LS hemi before that sounds wicked
Well, except for a big cam high compression BBC.
@@badluck4823 HAIL the BBC, still the KING!
If you like the sound of high RPM NA small blocks go to an NHRA Hot Rod Reunion and check out the Jr Fuel dragsters. Cast iron small blocks limited to 430 CI injected on methanol. They rev to what sounds like well over 10K and make the most glorious sound! Oh, and they are fast as hell!
@@danmyers9372 worth the watch I did catch that .
Uncle Bob is priceless, one hell of a engine builder. The S-10 is gonna be even more of a beast than ever now, I can`t wait. Y`all did a outstanding job!!
I love someone like Bob .Its awesome watching a true master at his craft and listening to what he's saying and learning little things. You can tell he knows his stuff for sure. Dude is a pro.
Lovin Billy's dedication and determination to get better and go faster. You don't hand your stuff to some big company and say "Make me fast!" You learning everything to be complete and well rounded racer! Can't wait to see the S10 back rippin!!
Good to see Bob is still smiling. What a wonderful man. Thank you for helping my grandson do this right. God bless.
I love to read the comments, yours was one of the best.
Nothing like having your Grand Mother in your corner pulling for your success.
To you God Bless and Take Care from Michigan.
Awesome reply
@@jerryfrederick6610 Just add, your Grandmother's Apple Pie."
Everytime an SRC video ends, I wish it was longer.
Keep killin it guys!
The S 10 is going to be on a whole new level now
I disagree. That truck can make 2,000 hp but it won’t put it down on the street. It’ll make the 1500 hp it is 😊
It's going to twist in half eventually.
Yeah it's their first rodeo oh please let em live so much power could be launched in to space
Back bumper launches like Farmtruck coming soon. 😆
Amazing how fast it revs from 6k-8200. Its like your spraying it!!!!
@@aady4697 aaayyy
He's a humble man, long live Bob. ✌️
Big respect to bob Mcvey the man is the real deal
It looks like this machinist knows what the hell he’s doing
He's a lot more than just a machinist. He's a builder a tuner and just a all around knowledgeable guy. He's pretty bad a**.
With all of the great work and support Uncle Bob gives, he has definately earned a sponsorship type deal, promoting his business with a good sized decal on the truck.
Alcohol doesn't add more heat to the oil, it takes heat away from the water due to latent heat of evaporation. Some big alcohol cars don't run cooling systems due to the cooling effect of alcohol.
Bingo. The IAT, EGTs, and everything else is cooler so the water temp drops a lot. The oil is under pressure, and eating friction no matter what the fuel is, so the oil temp was relatively normal.
Revs like it's got a flat plane crank in it, loves rpm. Sounds incredibly strong, Bob definitely knows his stuff, great job guys. Wonder what she is going to make with 30 lbs of boost. Go fast and be safe. God bless you and your family and friends.
Exactly what a screamer completely different sound like a indy flat plane.
I would figure 30-40hp per pound of boost.
600hp na X 2 atmosphere’s = 1800hp approximately. 1 atmosphere = 14psi
@@kennethwindstein2907 i believe the truck is capable of makin 2000hp
@@bird197196 1 atmosphere=14.7, and w/slight loses, its better to round to 15psi w/turbo, and w/centrifugals superchargers, it takes 19 to 22psi to get 1 atmosphere net power, cause it takes so much power to turn the impellars with the engine. If Billy pumps the boost up to 40psi, it could make 2,200H.p.! Out of a 372cu.in. small block=Wowzers!
Nothing sounds like a small block at 8200 thats music to my ears.
Hell yes!
nothing on earth can compare to the sound of a screaming small block chev i hope that engine can withstand the beating that is coming
Mine too especially if it's pulling a hard load .a laboring engine sounds great like at tractor and truck pulls
It’s Like Fine Wine. With Time it only gets Better . Leaps and bounds from where it all Started. 🔥🔥🎥💪
Great video! Great new motor!!... that will rock the racing world ....SRC / Billy is blessed with the best racing crew in the world! and Uncle Bob is a constant professional who really cares !
They're a bunch of good people sure enough, but I gotta hand the best crew to Ryan Martins people! They win way more than they lose, they got it down to a science!
Billy, what you are seeing when you force the water temp to be much colder, like with what happens when running alcohol from gasoline, is the engine now relying on the oil to keep the parts cool. Yes. Alchol burns cooler in the chamber, but it still produces heat in the parts and if the parts can't transfer heat into the coolant as quickly and the coolant is being forced to stay cold, it can't do it's job to absorb the heat, so it relies on the oil to do it. Don't confuse running alcohol with NO heat. The combustion heat goes down a bit, but there is still friction and moving parts still get hot.
Technically, it's not the coolants job to keep the oil temp cool. In reality, when the water IS able to absorb the heat, the parts run cooler and the oil doesn't have to make up for it, so it runs cooler. It still absorbs heat from the parts, just not as much. Hence why in a typical running engine, water temp rises faster than oil temp and usually takes oil temp much longer to rise, but ultimately oil will be slightly higher by about 10⁰-15⁰ in a controlled atmosphere. The more you hammer on it, the coolant stays the same but the oil temp rises considerably.
Colder water loses it's ability do absorb heat as quickly, because by nature the colder you make it, the more heat it releases not absorbs, until it ultimately turns to a solid form, ice. The colder you make the water, the less efficient it is at absorbing heat, and in turn actually acts as a thermal barrier, or insulator, holding the heat in. When you force the "barrier" to be cold, everything within the barrier becomes hotter. Now the oil has to work harder, and for its efforts, becomes hotter.
This has been the norm when switching to alcohol as fuel. Not a bad thing, since you need the hotter oil temps to burn off moisture and contaminants in the oil from the alcohol. You also want to run a specific thicker oil in alcohol engines to make up for that. I use Bradd Penn 20/50 race oil in these.
FYI, colder running temps, colder intake charge, combined with hotter oil equals more power.
What you were experiencing was pretty normal. Nothing wrong with hotter oil temps, to a certain degree. Definitely something i would be monitoring in a race engine. Many different things can cause hotter oil temps. What i listed was mainly because of the back to back change in fuel only and why it is happening. Hope this helps.
Look at uncle Bob he looks like a kid in a candy store it look like he was more excited than Billy. Uncle Bob your a rare man indeed. Wow Billy I'm impressed that little 372 is a screamer and definitely looking forward to seeing it in the S10 and making killer hits. Best of luck and I sure hope that 372 don't find your weakest point. As I always say Tommy your doing a awesome job. God bless you all and as always be safe 👍
Hats off to Bob he's the Man !
I'm curious how it's smaller and will make more power. Is it because your reving it higher?
@@havocracing6019 Heads and cam combo makes the power, shorter stroke helps keep piston speed down in higher rpm so internals has an easier time in high cylinder pressure.
Uncle Bob. He's the man. If he can't do it nobody can. That's that old skool machine work. Good job Bob.
@@chrisjay7736 I understand stand that. But it's missing over 50 ci
@@havocracing6019 shitload of compression
As I posted on the original reveal that Billy was building a 372…
He better be ready for RPMs!!!
Going to be totally different animal.
So so so so so so SOOOOO glad you all are going through this process with Uncle Bob and breaking it in and trouble shooting on the dyno! Incredibly valuable experience and will make the process once it's in the truck (hopefully) a whole heck of a lot smoother. Kudos to all of you guys, can't wait to see the fun ahead for 2023 sounds like a WHOLE lot of upgrades to the little truck besides a healthy new heart!
Billy liking Brittany Auto
As a engine assembler/ machinist in a race engine shop, we install bronze bushings in the lifter bores with a Rottler F69A, we buy them plain and then calculate where the lifter travels and drill a .040 oil feed hole in it to control the flow, then the slot size isn't as fussy like what you went through.
We do have a Superflow 901 engine dyno with improved water brake to help with water loading to help prevent run away power during the run.
Really cool to see all the learning from doing it the hard way. Bob M. Will forever be in your toolbox of knowledge if he doesn’t even see you again. Thanks for sharing this experience.!!!
Father like son always good content y’all’s 3 channels r the best out there
The alcohol keeps the top end cooler but the rest of the motor is still under the friction forces producing heat. The fact the top end gets cooled so fast does not allow it to pull the heat from the oil going thru the motor as fast as it does. Just like a radiator with a thermostat. It holds the water still until it pulls X amount of heat, then flows again to pull in more cooler water to heat soak again. I would assume thru physics if you could keep oil pressure up but flow low on the oil it would balance more as there is longer time sitting in the cooler parts of the motor. Just be sure to run an oil cooler when you switch to the new fuel system now you know there is that much difference.
Or put heads together and come up with an oil pan chller system where heat soaks off the pan and gets cooled externally like a computer water cooling system.
Never been a chevy guy but I give respect 🙌 yaw are truly passionate about what yaw do and yaw got a Hall of fame Dad can't wait til spring truck going to be nassssttttyyyuy
Don’t feel guilty, Brittany got me too 😂 . I like the way you figured out the oil issue, I commented once before that once you start building your own engines, that’s elite status. 🙌🏁🏁
Britney is famous! that motor should be a ripper in that little truck!
And that's the difference between in a hurry and doing it all right the first time with the best of the best an someone who knows an cares
BRING the thunder. I woke last night to the sound of thunder. IT was a small block What size I wondered.
I'm so stoked about the 377 S10 gonna be a big contender when you get done this round.
Fuel/octane have nothing to do with engine operating temperatures. You likely have another problem that seems to only be happening the times you run 91 vs E85.
It isn't a "problem". It's what happens.
Sounds like a Beast. With Practice comes Perfection. With the knowledge you gain from every build. 5 yrs from now. Youll be one of the best tunerr/ racers in the sport and in drag racing in general. Big big gains. Proud of All who put their parts and wisdom to making it come alive. BEST of LUCK. And thanks for taking us along
I'm a little surprised it didn't make more with 372ci and TFS heads. I believe I have seen a 358ci 9.5" Windsor make 595hp with TFS 11R 190cc heads. Not bagging on your work, I always thought a 4.125" 3.48" stroke high revving SBC would be sweet. I have a feeling a 377ci 4" x 3.75" would probably be able to make just as much power, if not more and not require as many rpms, even if they were made equal with 377ci each and a 4.155" bore in the opposing engine.SBCs are still the budget champion for a regular guy builder, they're not necessarily the best option out there for all situations. LS and 9.5" Windsors are extremely viable alternatives.
She was getting me with them damn short she had on during drag week
She’s sounds pissed af!!!!!!!!! 🔥BOB knows how to build a motor!!!!!
It is going to SCREAM!!! Can't wait for spring! It's going to be a long winter, time for lots of work, and killer videos for all of us to enjoy! PEACE ✌️
That's cool guys... just keep moving forward... also I would like a Bob McVay t-shirt.... the one he wearing, like it
Job job gents, you could feel the excitement when that nasty lil thing REVed! Excited for yall. Cant wait to see it run and the upgrades coming on the truck. Loved the collaboration between the different Generations. Nice numbers! Gonna fly out the back door- Get Some Get some haha
Yea no I'm cool with females working on my engine, I prefer it actually.
Hell yeah guys💪.. can't wait to see this thing hurting people's feelings
Man that's one NASTY small block!!!
Now you got to build some custom big tube headers
Bob is the bubble's of engine tuning. I love Bob. A master of his craft.
Great job guys!! That little 372 is going to be REALLY strong when you add EFI & boost to the combo!! Now is when the hardest work begins as far as trying to get those rear tires to hook just the right amount!! It's going to be fun watching the progress over the winter!! I'm looking forward to the spring & seeing all of the updates for the Nova, S10 & the Falcon. I've got a good feeling this upcoming race season is going to be the best one ever!! Thanks for bringing us along!!
Efi usually loses peak hp
Alcohol will run cooler PERIOD! I have actually seen times where the intake would have frost on it, Your combustion temps however will still be there and possibly even a touch warmer because you typically run more timing with alcohol ( HENCE THE REASON FOR RUNNING ALCOHOL IN THE FIRST PLACE ) I think if you were to time how long it takes to bring the oil temp to 180 on racing gas vs alcohol you wouldn't see much difference, It is deceiving because when you would time how long it takes the WATER temp to come up on alcohol vs racing fuel you would find that the water temp of the alcohol would come up considerably slower than the racing fuel which can also be another reason for running alcohol., Common in cemented blocks etc.
Sounds like your going to be shifting it at 8200. Now you just need to make sure you have a converter that is going to work best with that combination.
The converter he has now is probably a little too tight download for that engine. His last engine made quite a bit more torque downloads than this one does. But I bet you it's not tight enough up high for when he really starts throwing the boost at it. You can probably do a stater chand it would be OK until he decides to really open it up at the track or no prep at a track.
Lol Britney automotive got ya Billy 😂
OMG I’m so proud of the hard work you guys have done to build this monster motor. With boost it’s going to be insane. Thanks to all of the supporters of this fantastic family and friends.
Can't wait to see how the S10 and falcon run with new motors in both of them 😀😀😀😀😀😀
God forbid you tell that woman anything about cars though. She will block you so fast for offering info
Bob is a great mentor. Patience is second to none. Your new motor combo is a killer piece.
Let’s face it, your watching Brittany Automotive because she’s hott lol
I know your dad won’t like you going EFI but it clearly is time. At the power level you are making having the ability to tune each hole independently is so critical.
I know this change may make your dad feel it but unneeded (I am older than your dad and get it) but it is a part of letting go of your kids. It doesn’t mean Billy doesn’t appreciate all you have taught him Bill!
17:26 - The big disparity in the cylinder EGT’s here shows the drawback of a blow through carb set up. It just can’t compensate for any distribution issues inherent in the intake manifold.
I told him to put EFI on it. I’m not interested in babysitting it anymore
@@theoldmansgarage - Wow, that’s a change. Good on you Bill!
I know this sounds crazy; but I’ve seems some combos; where there was injectors with a carb on a nitrous combo (think old pro mod). The injection was just used to trim the cylinder to cylinder differences a bit better and keep to tube up more stable as atmospherics change.....It sounds over complicated but, I could see it as an advantage, given there’s no intercooler on the truck, and a carb does better introducing the fuel further upstream for charge cooling.....just a thought.
He must have been talking about Brittany Automotive lol she got me as well laying across that beautiful LT engine .
Hahahaha I was watching her video before yours dam yoga pants
what is the best way to get a Bob Mcvay t-shirt? awesome stuff guys, good job Bob !
Engine sounds great but in all honesty, I would’ve thought it would’ve made a little bit more steam than 600 being an 18° engine
Tommy, that was a great intro. Billy those funk tests were awesome, she sounds sweet.
MONSTER BigEnd Backside wheelies coming soon
I would love to have Bob in my area he’s definitely a awesome machinist.
This is how Legends are made!
The micro attention to the final details is life!
Five star buddy...
In reference- methanol is derived from alcohol, has two less carbons thus the power burn rate . Alcohol thusly will produce more pure power the on burn rate buddy!
I cant wait.man i sure love to see billy the kid and that little whistle he makes before he comes flying around all these BIG BLOCKS AND MONEY CARS (GAPPED BY STREET CAR) LMAO. Man i have loved learning so much from you billy old man and honestly jjboss. Big chief... Take these old hot rods clear up function of how these little small blocks are so tough.i have 283 outta old impala with good set iron power pack big flow valves.now jj said go through it like little humingbird. And screw you in 2 sets of 350shots nitrous. Make damn sure i have tough rearend 4-10s tough trani and great brakes. And last of not least best seat harness laundry out back and best of best cage around me ill be fine ...
We need a Uncle Bob shirt 👚 asap!!
What’s up with the Britney reference? 👀
Need some hoodies with Bobs logo on them an give him the profits, after overhead. I know you pay him but dang that man is an awesome builder

Really looking forward to that content 💪💪👍
Extremely impressive. Goes to show the right parts mated together will definitely improve power. Hope to be there some day with our race program. Have a long way to go but we have to do it on a budget, one or two components at a time with lots of upgrades to make from one end of the car to the other. Can’t wait to see the S-10 make a pass.
Billy that smallblock is set on kill mode.Uncle Bob is the man.Congrats to Tommy on the content with Allison's Dart.Its nice to see all of the knowledge you guys are learning.
Uncle Bob looked happy as hell you and him.both had big smiles on your faces great build can't wait to see it in the truck with all the upgrades
The sound of that new motor at 6500 rpm+ is wicked. Like its possesed! That thing is gonna something to watch once you get it on boost!
Can’t wait to see that s10 haul some ass at a no prep event. Great job billy
The reason for increased oil temps on 85 or alky when idling or warm up is because of the high volume of fuel needed with those fuels, and oil dilution past the rings as you would have seen in the past, well that fuel past the rings carries combustion temps with it, there is the reason for higher oil temp.
That was a good video, thanks for sharing and figuring out the oiling problem on your lifters, good job on passing that information to all fellow racers and small time engine builders.
Lake Speed has talked about that oil temp issue many time's in great detail. He says you want to run a specific oil with special additive pack as the alcohol kills some regular additives that aren't made for it. That extra friction caused by the wrong oil generates much more scuffing by the rings which generates the hotter oil temps
Fuel burns different some burns hot than other fuels that can effect oil temperature every time I haul feul for a living and if you look into how fuel burns you will understand that not all fuel burns the same and they act differently
E85 burns cooler than gas so why does it make the oil temps hotter immediately
Uncle Bob is the man! Allowing you and the Old Man to use his shop and his willingness to show and explain his building and tuning techniques says a lot about the respect he must have for y'all. Having people like Bob behind you is what's needed to make great things happen.Congrats on staying positive and getting one hell of an engine up and running.
foxbody funerals coming soon in a town near you😆 I can't wait to hear it on the chip😬
Long live Bob you guys rock
Solving the oil supply problem past the lifters was epic ! Excellent ! Wish I had an uncle Bob in my 318-340 days !
Good job guys. Thats gonna be a game changer in that truck
Not sure why but Brittany gets everyone. lol. She is good.
I like the way you all share your findings and not trying to hide it all. You all did the right thing holding out on russing for the races.... do it right the first time. And smoke them all.....
That lifter deal is pretty much par for the course on SBF and Lunati lifters. Congrats on the new bullet. Trick Flow has said in the past they run their hydraulic rollers close to 8k on spintrons. It’s no surprise that solids will easily get there.
