Bought a new 2019 Corvette Grand Sport, with a MANUAL TRANSMISSION, and it’s a great car! Huge power, fantastic handling, and with the magnetic ride control, the car goes from track stiff to cruising smooth in an instant. My wife even asks when we can go for drives in the Corvette Grand Sport, and that rarely happens with my NSX. Buy one, if at all possible, life is short.

This is the perfect c7

Impressive build, and it's refreshing to watch a build video without BS punk rock music.

Now THIS is the kind of content I like to see. GOT DAMN... 700 naturally aspirated horsepower is freakin' impressive! That 2 month turnaround time is super impressive as well!

Deadmau5 + Vette engine build = me happy

Incredible build by obvious pros. Well done and dope soundtrack too.

I am impressed with the wrenching - using hand tools - something very organic and old-school about it. A real hands-on connection. Awesome!

Very professional build and all the attention to detail is very impressive and your shop looks immaculate!

I really like the styling and videography of this video. Keep up the good work.

You have a very impressive facility. Its easy to see why you have such a great product

What an amazing build. I like your shops attention to detail and the obvious love for the job. Great work!!🍻🍻

Best video I have seen with integrity!!!!!! Amazing company.

Exactly how it should've came from GM. So damn cool!!! 🤘🏻

WOW, excellent video. I have a 17' GS and didn't realize you make built motors like this. Gonna have to do a little homework!!

Incredible team @ Katech Jason !! The very BEST ! All of you should be very proud of the finished product you guys deliver to the clients of Katech, job well done as always brother, take care, Happy Thanksgiving Katech team of professionals.

This was one of the coolest build videos I’ve seen

So awesome! Enjoyed watching this. So wish I owned a Z06 and you guys do the work on it.

Boost is great, but I love seeing how much power you can get out of a normally aspirated engine. The LS7 is still one of my all time favorite GM engines. Nice to see a big cube NA Gen V engine! I would have loved to get a good listen at the start up and idle, though.

The best part is the car is very quiet at idle...then BOOM!!! Engine and exhaust sound amazing, almost C8ish while revving.💪🏾💪🏾💪🏾💪🏾

Love the video and the quality of work is more than evident.

That was one amazing build and video.

Very impressive so thanks for posting!

Awesome video I got to come by in person on your next built keeping them coming

Best move.... we tired from Supercharger and Turbos ... we need something like this

So sick! Need a quality shop like this in South Florida.

NA 700hp manual clean build you guys are amazing!

Amazing what guys can do love your videos.

After only a few minutes I was hooked! I mean really, the level of pure craftsmenship when putting this engine back together proved this is some legit s*@$ :) massive props guys!

You guys should make a lot more videos of builds like this

Hollyshit!!! clean work! I wish i had the fund to build a 427 N/A GS to go along the Z06!!

Great video! This is my dream setup, that's one lucky owner.

Really enjoyed this!

Keep these videos coming !

All motor is badass. I would want one badass supercharged monster and one badass all motor monster. Best of both worlds

Wow nice work!

Sweet setup!

That was so beautiful *wipes away man tears

These boys seem to know what they're doing. 😎

Wow, this is truly badass! For a plebian like myself, 32K for this is beyond me, but had I the money...Oh yes!

Professional work

Always interested in NA upgrades...esp from Katech. Great job, gents!

Well done!

Mechanical poetry.

AWESOME VIDEO

The fact that no power tools are used shows your quality of work. Amazing build

God that car is Sooo sick

Amazing! 😮

Amazing!

Sweet frosted tips bro..

"If you want it done right. Send it to KATECH". TRUE STATEMENT!

I would absolutely love a chance to drive that car.

700 NA HP? Now that would be fun to drive. Nice work!

Nice build

all motor beast.. oh yes

That rear diffuser is sweet !

that look awesome

Really 9ice vid, keep it up

700hp N/A... You guys alien!

700 n/a HP? shut up and take my money

amazing!

cool video guys

Awesome!

I am in love, i will get a grand sport and send it to yall pair perfect with my c6 z06 I would like it with a big cam, ported heads and lots of NA power. You guy are really professional i am serious i will get in contact

With that much power, the driver better dominate everyone

That burnout at the end 🤤

good job

Australia needs Katech

you just talked me out of a C7Z06....I don't want a blower motor....I LOVE the LS7. I want NA 427 in a C7 and this is the answer.....BRILLIANT. This should have been an option at the dealer like the callaways.

I had a feeling they had to add sleeves, And I wondering when someone was going to build the ZO6 Small Block 427 up. It's a great motor!

Now that’s one bad Vette!

More content like this, please.

Good job bud

Imagine this in the C8. Katech needs to make it happen.

That was nice

This is why I drive a Chevy!

I own a 2017 Chevy SS Sedan with the stock LS3. I've been on the fence as to which upgrade to choose. If I were to follow the primrose path by others, I would have a new block cam-ed, ported with internals, coupled to an SC, and tuned as a daily. Conversely, I just can't shake my desire for an NA alternative. This video inspired me with the cleanliness of their shop and how they approached the build with surgical detail.

Finally a manual. I dont see those enough anymore.

BAM !!!!!!!!!!! KICK IT UP A NOTCH !!!!!!!!!!!!!!!!

This is EXACTLY the Engine the CORVETTE GRAND SPORT should have, with the Z07 PACKAGE. AWESOME CAR! !!

Now I SEE what y'all cost so much... well done !! I'm impressed ! Y'all hiring ? Looks like a place for me .

Niiiiice!!!

Yes lawd ! Finally a N/A 427 LT1... where those darton sleeves?

This is the PERFECT Corvette. All black GrandSport with Steel Brakes. 700 N/A horsepower. MANUAL with Forgeline wheels. Omg. PERFECT. #SAVETHEMANUALS

It all looks beautiful I was wondering if after all the working of putting everything back together perfectly to the best of ur ability does the engines have problems where you’d have to pull it all apart to fix stuff or if it’s done right it should last a long time with this much horsepower?

This would be perfect in the new C8.... Wow!

I can't wait to get my GS so I can send it there and only 35 minutes away.

I have decided to take you up on your idea to see what is runs at the track that still will not explain the poor numbers on the dyno,thanks Bob

When building an engine like this, don’t you have to run it for like 200 miles with break in oil or so to create cylinder and piston wear patterns before all out dyno-ing?

I'm a die hard GM and N/A fan, and seeing 100hp/L out of a 427 is always cool. I know you guys stopped making Corvette race engines after GMPP brought everything in house in 2010. However, I hope that your work with Pratt & Miller still created a strong bond. I have several questions, the last of which is more of the blurred line between race and road engineering. 1) When it comes to the Gen V LT1, how long do you think it will take the aftermarket to come up with a true tall-deck block with direct injection that will support 100hp/L and 500ci? The LSR-TDRC2X block from Concept Performance has been hailed as the next big step for making reliable power for the LS platform - and it supports up to 505ci SAFELY. Obviously with the LSR block reliability is key, and it supports 505 ci (4.180"x4.600") safely before the wall thickness is no longer sustainable. But it's still an LS-based block, without direct injection. Also, the tall-deck version only weighs 120lbs, which is kind of crazy. A tall-deck production LT1 (LT7?) block that weighs 120 pounds would be sheer insanity. 2) Going back to the LS architecture, an engine builder (who shall remain unnamed) using what looked like a Dart block, old-school intake, made nearly 870 hp/740 lb-ft out of a 'conventional' 502ci (4.165"x4.600") build - and it was meant for a STREET DRIVEN car. They posted the dyno run on KZfaq only a few weeks ago, and it looks entirely legit. What kind of cam and compression ratio would support such a ridiculous amount of torque AND power, even with a huge stroke like this? 3) Everybody talks about drivetrain loss and the different ways to calculate it. You lost about 76hp from a 700hp build, so I'm gonna round it and call it 10% loss total. Most people land somewhere between 8 and 15 percent - but obviously it's different for every engine, transmission, and drivetrain package. Which transmission did you get that loss with, auto or manual? And if it was the manual, how much more or less power and torque would you see at the wheels with an auto (or vice versa)? 4) Lets say we take the aforementioned 502ci crazy engine, and we drop it into a car running a CF driveshaft and a 9" rear with 3.00 gears. What would be the difference in horsepower and torque at the wheel with a traditional manual (say a beefed up T56 Super Magnum) versus a 6-speed paddle-shifted sequential box, like something from Albins, Holinger, HGT Precision, or the like? And would it be practical (not necessarily comfortable, but practical) to run a sequential on the street assuming that its torque capacity exceeds 1,000lb-ft? I've heard that the HGT boxes are the quietest and have barely any gear whine - plus they're EXTREMELY light.

There is a heaven

That house they drove past , just damn

40psi of oil pressure at 4800 rpm. These motors sure are some voodoo magic

Wow!!! That’s all I have to say.

Deadmau5 song. Love his music !!!

Now THAT is a car. #NA4LIFE

Can you do an e85 tune after? For more hp. 🤔

Nice 👍🏿

How does power to weight for this car compare to a H/C/Exhaust C6 Z06 with 650HP? How much was this build?

This is what the C7 Z06 should have had

This is what im talking about!
