This has been great. I think you have learned a lot and that’s the best part of it all. I love how you aren’t afraid to ask questions. I feel like In todays society people feel ashamed if they don’t know something. It’s ok to not know everything. I am 35 and learn things everyday. I am proud of you for sticking with this and the end results will be even more satisfying. You go girl

[@loubianchi2577]

Kayla....Your mechanical side is putting together an impressive engine and your artistic side is making it a real looker. Great job!

[@grahamerosewarne6656]

Kayla your should be so proud of yourself. Most people are scared of having a go at building there engine's. Can't wait to hear it running. Great job Kayla 👌👍 Aussie Fan 🤘🇦🇺💪

[@andrewcammer2535]

Overnight parts for Japan!? You're going to enjoy the heck out of this. Great power - can't wait for you to share!

[@jirving24]

It's not everyday you can get an opportunity to get hands on with your engine. What an experience!! Thanks for sharing!

[@chadoliver2966]

Kayla this is soo cool seeing you put your own motor together. Keep up the great work. Your car is going to be a beast once its finished.

[@victorwilburn3498]

Kayla: You have now surpassed quite alot of car people with this engine build. The work is meticulous and once the car is finished and you mat the throttle in that thing..LIFE CHANGED👍.

[@ssoffshore5111]

I haven't seen one of your videos in a long time, you've come a long way! Looks like a great build!

[@C10Scottsdale]

I enjoyed the video greatly Kayla, Thank you. I'm sure your engine will rock! Sorry to see you fall when the socket slipped while torquing the rod bolts, Proper footing is a key element when using a torque wrench as you found out. We've all stumbled at some point in our lives but at least you're OK.

[@bighouse1695]

That was awesome watching him spin the crank with the speed wrench and watch the pistons move

[@los8956]

good job block is coming along looking good, so many 'that's what she said' moments 😀

[@dparis1768]

Good job on the build!!! Nice series of videos, your camaro going to be monster!

Kayla you’ve convinced me to pay the $5000 option to assemble my Z06 FPC engine at the Bowling Green factory

[@timbo2ssrs]

[@roydagger]

Kayla's is such an attractive girl. Especially when she has her hair in a top ponytail. Love it!

[@bmwe30guy]

Hope to see 625-650whp with Az air and E85? Assembling long blocks is very therapeutic with the right company and some good music

[@robertwestover2125]

Great learning experience for you ❤

[@MrSamz400]

Kick ass and take names woman!! And be careful

[@clydegreenwood5673]

What a beauty

[@johngrimley3523]

Kayla the engine builder =)

[@gloriamaletta8667]

Sweet engine prefer this 416 to the new GM 5.5 LT6 engine 750 crankshaft horsepower should give you 620-640 rear wheel horsepower I'm not a big fan of manual transmissions but l can imagine how good this engine would be connected to a very built 6L80e automatic transmission with a 4200-4800rpm Circle D lockup stall torque converter even with the stock 3.27 gears low 10s possibly high 9s should be a piece of cake and could be driven anywhere naturally aspirated I'd imagine this engine will be a monster from 4000rpm- 7200rpm while being street friendly from idle-3000rpm only wish l had this engine in my 2011 Camaro SS but I'm thankful for the GM performance LS3 495 horsepower crate engine in it wish l had the cash to do what you did at GPI to me it's the absolutely best setup available for all around street and strip performance enjoy it good luck with it I'm sure GPI building a engine like this with all the upgrades would be approaching or close to the 20,000 dollar mark with parts and labor this engine with 11.7 to 11.8 to 1 compression ratio running on E85 would be absolutely perfect

[@dutch971]

A lot of opportunity for some good comments in this video.

[@KaylaRundle]

The Process of making this video was hilarious. Had to make quite a lot of cuts in the editing process that KZbin prob wouldn't allow.

[@alandelgado798]

awesome!

[@oliverplowboy]

What cam are you using kayla. Im building 416 myself

[@TyphoonJetPilotMeteb]

Kayla Rundle I hope this message finds you well ❤

[@young11984]

Oh yea that was a lot of editing, reminded me of the time i helped a friend put her engine together. Everytime i said lube it, blow it or any of the standard terms she would laugh and of course it turned into sexual terms for her to remember lol. Was fun though

[@jamesh1273]

What cost build that engine and can get one that’s built already and ready to install already

[@jimromero1384]

I like it I like it alot!!!

[@Schlipperschlopper]

Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station fuel pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called "Abgasbespaßungsverbotsverordnung BABVVO" in German.)

[@daldrickwhite9067]

Hello.... Can you give me the specs on this engine please.... From Cam to pistons

[@bryantracing3022]

Your smokeing hot

[@popatop6657]

Keep that oil off of them rings!!!! If you need ring compressor oil use ONLY A LITE OIL like WD 40!!!!

[@STARSHIPTROOP]

What HP are you expecting? 650-750 ? Now do you go E-85? maybe adding methanol or straight pump gas ?

[@KaylaRundle]

Expecting exactly those numbers. We are running it on Pump E!

Hi Kayla What would you say to me if you were about to leave to drive somewhere and saw that i was laying under your vehicle would you ask me to move or take off walking ??

[@KaylaRundle]

My car is too low for this to happen

[@katieowen3858]

@@KaylaRundle Well in that case Kayla, I will just glue my face to your exhaust pipe then i know you can't drive it anywhere then . :P

So would you give me your car or start it up anyways ?

[@jaimeedwards1269]

Who the hell was saying it's common for a N/A LS to make 700whp that's like 800+ at the crank? Sure with a big cam, hi compression, race gas, and alot of head work it can make 800hp N/A but that's a full on race engine. I bet you're combo will make around 560whp. I built my 2010 Camaro myself. built the engine into a 417ci with a F1A-94 on 10PSI boost and it made 720whp. i need to upgrade fuel pumps AGAIN then I will give it more boost.

[@ricktaylor3748]

No. Her 416 ci engine can easily make 600-750 horsepower. With the right cam, and some trick parts, it can make 800+ hp. You must've never owned any Chevy engines.

[@ragtopdlxzl1]

The 750hp for that set up is at the crank and without accessories (-15,20%). Even so that would be a great number. If you add boost the numbers go up quickly. Her engine would have a 4 in stroke with a 4.075 bore for 416 cid. Our ZL1 has a LSA motor at 419 cid.The only thing left is to get a bigger blower for more hp. I would have put a turbo on her build to which 1000hp is easy to obtain.

[@jaimeedwards1269]

[@josephsolomon8623]

700 horsepower easy

[@MrJoseeclipse123]

750 nah

[@reifonseca5767]

No way 750 hp ....with supercharger yes or nitrous.you be lucky to make 600/625

[@lars277]

Normally aspirated. An engine is not an organism. A bodybuilder who does not take PEDs is a natural body builder. A normally aspirated engine is an engine that is equipped like millions of the run of the mill engines, with no forced induction. Your engine is a normally aspirated engine. Just saying. There is nothing natural about a man made engine.
