@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 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.

[Ada-znpw]

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.

[carolegischel]

Good to see Bob is still smiling. What a wonderful man. Thank you for helping my grandson do this right. God bless.

[lonewolf]

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.

[billyray]

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!!

[ls_]

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!!

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.

Everytime an SRC video ends, I wish it was longer.
Keep killin it guys!

He's a humble man, long live Bob. ✌️

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.

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.

[Rockyxplore]

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 !

[Dikka]

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.

[jkK-lwlu]

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.!!!

[Entertainment_Enterprise]

The S 10 is going to be on a whole new level now

[LucoreAuto]

So so so so so so 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!

[jacobohara]

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

[garry]

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

[kennethchapman]

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.
