Chevrolet C3 Corvette LS Swap 6 Speed Manual Transmission Swap at V8 Speed and Resto Shop Part 4
This 1969 Chevrolet Corvette Convertible came to the V8 Speed and Resto Shop in need of some serious power, performance, and reliability upgrades. This C3 Corvette was powered by a non-original and well worn 350 cubic inch V8 backed by a Muncie 4 speed manual transmission. The goal was a Corvette LS Swap to add modern power to this C3 Corvette. A C3 Corvette LS Swap seems to be a simple job at first glance, but the more you investigate, you'll see that a C3 Corvette LS Swap isn't quite so simple.
PART 1: • Chevrolet C3 Corvette ...
PART 2: • Chevrolet C3 Corvette ...
PART 3: • Chevrolet C3 Corvette ...
In this episode, the V8 Speed and Resto Shop crew installs a custom fabricated air intake and K&N Filter to feed fresh air into the Chevrolet Performance Parts LS3 480 HP crate engine. The LS3 is managed by a Holley Dominator EFI system. The LS3 is finished off with a pair of Corvette engine covers.
Next, the team installs a set of Wilwood disc brakes designed for the C3 Corvette. C3 Corvettes have 4-wheel disc brakes installed from the factory, but Wilwood 6 piston calipers were installed up front, along with Wilwood 4-piston calipers on the rear of our 1969 Corvette. Wilwood Corvette brakes are direct bolt-ons for C3 Corvettes. The brake system is also upgraded with a Hydratech Hydroboost brake booster unit, which provides high clamping pressure to the Wilwood calipers. The Hydratech C3 Corvette brake booster install will improve the Corvette’s brakes substantially.
The next chapter is the 17” Corvette Rally Wheels from YearOne. These YearOne Corvette Rally Wheels are machined aluminum, but they are the correct backspace and offset for C3 Corvettes. These aluminum C3 Corvette wheels also clear the oversized Wilwood brakes.
A C3 Corvette Dakota Digital VHX gauge system is installed, which allows the Holley driver to see the same information that the Hollley Dominator sees from the LS3 engine while driving. Dakota Digital VHX gauges for C3 Corvettes bolt in place of the original gauges, but provide modern movements and network connectivity to provide speed, RPM, oil pressure, temperature, and a multi-function display to keep the driver informed at a glance.
The 1969 Corvette roadster is also fitted with an air conditioning system from Vintage Air. Vintage Air Gen IV systems are made to fit the C3 Corvette, and provide heat and A/C to keep the driver comfortable. Music is provided by a Custom Autosound USA-630 AM FM MP3 Bluetooth audio system. The Custom Autosound C3 Corvette radio does not require dash modifications for install.
The 480 HP Chevrolet Performance LS3 V8 uses Hooker cast iron header manifolds, and the V8 Speed and Resto Shop crew fabricated some stainless steel side pipes and mufflers using parts from Magnaflow Exhaust.
The Tremec 6-speed manual transmission from Modern Driveline is now installed. With the Tremec T56 transmission tunnel modifications, the team fabricated an aluminum center console cover piece designed to fit in the original mounting hole but modified to accept the T56 6-speed shifter in the C3 Corvette.
Once completed, the 1969 Corvette LS swap and T56 Magnum 6-speed manual transmission perform like a late model Corvette, while keeping the look of the original. It now has over 480 horsepower, six gears, improved Wilwood disc brakes, air conditioning and modern audio, and is as reliable as a new car! And the driveline is under warranty!

You can have anything you want in a car as long as you have the money...
Enough money and time buddy :) that’s all it takes
Awesome build. I'd rather have one of those than a new 2020. Thanks for video. Nice work.
Thank you for the kind words! New performance with classic styling is an attractive way to go, for sure.
Gentleman, that was absolutely Stunning and Perfect execution. Forget the Corvette crowd that brow beats with the " It's incorrect " police. Anybody would be proud to own that car.
Thanks so much for the kind words! Cheers!
Beautiful! I’d love to do this to my 73 vette.
BOOYAH! NICE JOB! I build C3's...but I can only dream of a project like this, for now I'm keepin em alive old school.
Amazing modern restoration !!!!!
Thank you Frank!
The C3 is by far the most beautiful in my opinion, I still can’t believe its so heavy though!
Mine is 3380lbs with 1/2 tank of fuel, AC, Power windows without me in it. And its a Big Block with a T56
The shop did exceptional work. Converting a 1969 corvette with modern day technology is not easy. It is like buying a new corvette. However, there is a downside. As things begin to go wrong you will have a near impossible task finding someone with similar knowledge to work on your car.
Thanks for the kind words Ben!
This shop does very impressive work. I know who I will contact when I get ready for a custom build, V8 Speed & Resto
Kind of you to say, we'd be happy to chat with you when the time comes! Thanks for the positive feedback MrRoninala!
I just did a ls3 480 swap on a 1970 impala and used Dakota digital. Takes the guesswork right out. Nice job v8tv
They do work well. Thanks for the kind words!
I personally don't need a radio. I love the sound of the car when I drive. It's soothing to the soul.
Its always great seeing a C3 get some love. This one is very nicely built.
I put Vintage Air in my ‘71 convertible Corvette a few years ago. It still works great. The biggest hurdle in the installation was routing the hose to the driver side vent.
Beautiful job!! That's the way a vintage Vette should be in my opinion.
Wow, thank you!
Awesome job, great build, really enjoyed the video.
Thanks a bunch!
Every time a brand new shiny part is unboxed on this video, I hear a subtle “ka-ching” sound.
Nice job Kevin, Trevor and V8 team!
Thanks Jay!
Best auto channel on CZcams. Nothing half arsed, no bullshit . Greetings from Adelaide south Australia
Wow Chisel, that's a very high compliment! Thanks so much for the kind words. We're glad you like what we do, we have much more to come. Greetings to you and all our friends in Australia, we have many! Someday we'll come visit and meet in person! Cheers!
Absolutely awesome job. The owner should be darn proud. Well done guys!!!
He's a lucky sum bitch
Thank you sir!
Awesome build. I'm debating between building mine into a 383 stroker or just dropping a LS in there. The fitment issues make the stroker build look like the easier option :)
It is the easier option fitting the stroker. I installed a 454 in mine lol.
Awesome job! I like that type of tuning with modern technologies on classic cars
Great job Guys! That's a 69 anyone would be proud to own and drive. 1st 2.66, 2nd 1.78, 3rd 1.30, 4th 1.00, 5th .80, 6th .63, Double overdrive makes a awesome hwy. cruiser. I really like the eng. specs on the console all the work you did was Premium Quality.
Thank you so much! It's the details that make the difference. We appreciate the kind words!
Truly amazing, great video.
Thank you!
Beautiful car, well done.
Thank you! 👍
That was 'Seriously Impressive' ! I can appreciate the level of quality this team is able to achieve with modern technology & a 'Good-Nack' for solving problems !
I walked the walk & talked the talk in my own Auto custom shop for over twenty five years, 'when I wore a yonger mans clothes' ! 😏😎😉 Great Job Guys !
I just finished watching this series on this '69 and I have to say V8TV has done an absolutely fantastic and quality work on the conversion of this Vette. True American quality and craftmanship. You guys are awesome!
Thanks so much for the positive feedback! The team really enjoyed working on this one. We appreciate your kind words!
Gorgeous. Great video!
Thank you so much!
Thats Top Class Work
Thank you for the positive feedback!
@@V8TV That's no problem over in England it only at shows you see cars like the old muscle But not anything like that 👍
Came out nice 👍
Thanks
Bonjour à toutes l'équipe, vous avez réalisé un travail magnifique. Bravo.....!!!
Merci beaucoup, nous apprécions vraiment les aimables paroles!
@@V8TV , I'm so impressed that you would take the time and go thru the effort of replying in french. Says a lot! I'd do business with you guys anytime.
@@jackmidst8304 Thanks Jack, cars are cool across all languages, we wouldn't want to exclude anyone just because of a language barrier. We appreciate the kind words and would welcome the opportunity to do business with you!
Love the build , I would like to do this on my future 1981 corvette
Looking good
Seriously cool
Nice neat job.
Thank you! Cheers!
I put a T56 Magnum behind my 516 Big block, what a great choice, yet it was a pain also. Too bad I parked the car 4 years ago. Maybe its time to uncover it and bring it back out.
You should get it out!
@@V8TV I need to do something. The car just doesn't do it for me anymore. I bought another car, and I'm enjoying it alot!
Gumballer133 sell it and make bank
Did you get her back out or did you sell it?
I want one!
Great work, but a very expensive way to go. I'm sticking with the good old big block in my 1970. No fitment issues and lots of power, little heavier, who cares.
Nice
Okay
But ...HOW MUCH!!!!
I'm guessing 350,000.00. But there are some serious breakthroughs that were dealt with that are no doubt going to be part of future kits/ installations and that no doubt had some factor in cost savings to the customer..The tenacity that made this build possible was actually beginning to make me ill.the mock up and fab of the trans tunnel was more than I could endure. I had a highly dysfunctional relationship with a 69 roadster. Triple black, Hooker pipes T/A radials on cragers..The top always leaked..And it rode like a worn out pickup truck..No amount of money ever solved those two ultimate deal enders.
@@toosunakabooma1213 oh
You worked on the development of this kit?
A 6 speed manual from Silver State with everything is about $8-9k Car Effex here in New Jersey charged me $3k to install it.
Motor depends on what you want in it, brand new crate motor? $30-40k depending on what you want and HOW MUCH POWA BABY!
Figure shop time at $120-140 per hour.
Wheels and tires 🛞 between $2,000-7,000 depending what you want.
Brakes $3-4k plus install at $2-3k
So I would say under a $100k if you’re putting in a new crate motor.
$350,000 and your doing a new car that is going to be a body off restoration, rotisserie done body with a new chassis and everything you can think of.
So it depends on what you want to do restore, modify or go pro touring/show car.
If you’re just driving it and want to do the work yourself, just take it piece by piece and get it done.
That would be so.awesome.in my 78
Do you have a video with upgraded brake system for a c4 corvette?
the one thing they don't say is the price and I don't blame them! Fantastic work tho most definitely worth it!!!
WOW!! Excellent work gentlemen, that is a master piece. Love the video, new subscriber. I use to drive a 67 Stingray with out power steering, it was cardio workout. Did you have to add power steering to it?
We did install power steering, and a tilt steering column.
I want one...
What type of wiring harness are you using?
How long did it take to do this, amazing work btw
i found the caucasian version of Lawrence Fishburne
@@BrothaSoofi we'll take that! Thanks!
Great video! With the LS 3 and six speed conversion into a C3 do you have to use a big block hood, or will everything fit under a standard small block "flat" hood?
It should fit under the flat hood, as the LS was designed to fit in low modern Corvettes. Today there are some accessory drive systems that bring the alternator down tighter as well.
If a customer were to come in and ask for a modern day interior with a old corvette, would you be able to do it?
I just found this series and what an excellent one it is. I'm looking into doing something similar for my wife's next car. She has always wanted an '80 - '83 Corvette. If I can find a decent-shape body for a good enough price, I'm pondering a very similar restomod, but swapping the T56 for maybe the 6L80 automatic so it's reliable and easy to drive.
I fully understand the limitations of my question, but is there a way to have a ballpark estimate for what I should budget on the mods/labor?
Hello Sir, every car is also a different situation. However, we'd be happy to chat with you about what you'd like. If you get a moment, you can call the shop at 314.783.8325 or click to www.v8speedshop.com and fill out our inquiry form. Thanks for the kind words, we hope to hear from you!
@@V8TV Will do. Thanks for the contact info.
They did not make a vetted in 83 and the 84 was not very desired as u can tell by resale prices now
Wiper door and lights still vacuum? Also, what’s done to suspension? Mine was squirrelly as all heck with stock gear and power. I’d imagine it’s been upgraded somehow. Details please
Hello @Wooca, we did an electric conversion on the wipers and headlights and there were some suspension mods when we started. You can see all the details in the other 3 episodes - here's the whole playlist. Thanks! czcams.com/play/PLGV8X9X8baVizfPH6-qxNKrHmnGUAr81Y.html
This is exactly what I want to build (just not a convertible), you guys did an amazing job! About how much did it set the owner back?
Bryan, we typically don't discuss the financials of customer projects, and every car is also a different situation. However, we'd be happy to chat with you about what you'd like. If you get a moment, you can call the shop at 314.783.8325 or click to www.v8speedshop.com and fill out our inquiry form. Thanks for the kind words, we hope to hear from you!
On break systems. I believe the rotors need to be cross drilled too. We can make them run like they were trying to out run. The word of God.Amen.!!
Is this beauty for sale?
How much did this all cost?
How much did this entire build cost
When is it appropriate to use a K&N, (or any other brand), filter? I had an LS3 and now have an LSA and haven't used a K&N on either of those. What's the advantage?
Great question. We used the K&N in this case because they offer a huge variety of shapes / styles of filters, and their catalog provides dimensions for all. This way we can design a custom air intake and pick a filter to fit. That and we know the flow characteristics are better than a stock paper filter, and they last forever.
@@V8TV
Thanks for the answer!
One more quick question - you see all these people immediately slapping a custom intake on their stock Camaros - you'd have to tune it to get any benefit from it, right? And even then you're not going to notice a difference unless you start making drastic modifications? And because it flows better does it let more dirty air into the system?
That depends. There are some air intake systems that don't require a full re-tune, as the stock ECM can compensate a bit for slight changes in airflow. More drastic mods do require revising the tune for optimal performance. Higher airflow does not necessarily mean less filtration. Hope this helps!
@@V8TV
Thanks!
Witch tires did you use on these wheels?
Hello Robert, we ran BFG G Force comp 2 a/s 245/45R17 on the front, and BFG G Force comp 2 a/s 275/40R17 on the rear.
Hello I have a 1979 Corvette L82 and I like to put a LS7 in my car?
Will that work because right now.
Its automatic with transmission?
So I like add more power so if you can please let me know will the LS7 work?
Thanks.
Hello Daphne, the LS7 is a slightly different animal when it comes to LS engines, mainly because they were designed for a "dry sump" oil pan system, meaning they require an external oil tank, lines, and pump. This occupies much more space than the LS3 or other "wet sump" LS engines. And LS7 can be converted to a wet sump system, but that is an extra step in the process. It may be easier to make similar power using a modified LS3 platform to start with. The LS7 may bolt to your automatic transmission, however, we'd recommend a more modern electronically controlled automatic to handle the power of the LS7 and provide easier tuning and calibration of the transmission. This might require additional fitment modifications to the tunnel to install. These are general answers, we hope they help you with a bit of context. You can reach us at www.v8speedshop.com/contact and we'd be happy to discuss your ideas further. Thanks for the question!
Not to mention that factory ls7 needs heads replaced asap, you're better off with a sleeved block and have it built to whatever cubes you'd like with wet sump crank and better heads.
I just did an LS3 in a 75. Way easier than the LS7 would be. Good luck!!
So this is about selling products. Not how to make it fit. I already have a parts catalogue.
This is about sharing the story of how we built this car. We leave it up to you to decide if you can take on this kind of project or would rather have a shop do the work for you. At the end of the series, we hope viewers are more familiar with what it takes to do this kind of work. We do produce how-to videos as well, but those are noted in the title and description as such. Hope you can find some enjoyment in the series!
@@V8SpeedShop Yeah I know" right.
@@kevinwest3689 Right on. You working on a project? Are there some pics or other info we can help you with? Happy to lend a hand. Thanks!
What seats did you use for this?.
Ohh. And would a crate 350v8 be enough for the tremec 6 speed?
Could I put a tremec 6 on my current engine?
The seats are the stock ones that came with the 1969 Corvette. It is possible to install a 6-speed behind a small block Chevy engine.
Maybe someone can comment....Been a C3 convertible owner for 18 years.....When done, how much would this car cost if the owner decided to sell ?
Kind of hard to place a price on this.....
It depends on the
condition - body(fiberglass), mechanical
Miles
How original, (paint, engine, tires).
Clean title, how many owners.
It all depends on this and or that.
Everything is perfect except the beautiful red color : too bright for speed tickets .
Ha, true!
I thought the t 56 was for ford and gm?
There are bell housings for both.
This must have costed a lot
? What it cost to do this to my 1969?
Yes.
People who can afford this type of work never talk price. They find a reputable company, ask them to do the work and pay the bill.
Wants to keep it original, doesn't want it original, want's it original, doesn't want it original. I don't get it. Either it is, or it isn't. Doing whatever you want to your own car is great but it just seems inconsistent in this case. My L-71 1969 that I've owned for 52 years still runs great with almost 180,000 miles. It goes like hell and stops safely. With the GM HEI, Hooker Sidepipes and a few other mods, it runs better than factory. But, I have changed my car to suit my own prefs and never have worried about "original" which seems to be the big thing these days. Hopefully the owner will enjoy his car for many years to come. I plan to do the same.
Nice job on the car but I just don’t like the look of the over sized wheels on these cars.
The cool thing is that there are options to suit any taste. Thanks for the kind words!
You don’t see the wheels when you’re driving it.
With that low air intake, stay away from high water,...
Ah man, we can't drive a classic Corvette through high water? Well that takes all the fun out... 🙃
anybody gotta clue what this would cost, 15k i figure
It depends on the parts... the driveline and fuel system put you in the $15k range alone.
Dang, so this guy prolly dropped 25k to have this done then, its badass no doubt. To some people thats chump change though, and even then he's way under what it would take for a newer car to touch it. I'd go to gmperformance and buy that lsx 454, for 20k, insane power, more less plug and play. I'd have that tranny built up, and that package would hang w anything pretty much. Have you guys dropped any of those LSX's, that's really a helluva deal...Roost
Lol 15k
Brake package and wheels would be 5k just in parts. If I had to guess I'd say 40k would be a good start.
@@chisel83 well if you have it to burn I guess. I drove one of these that was for sale a couple years ago their badass no doubt. At the end of the day its an old car, feels old, drives old. I'd rather have a new one but I understand the love, that c8 i'd rather have it and it'd spank this old one except MAYBE on the highway and i'm not sure even there the old one would win. Fine ass car though
WHY SO MANY HOLES IN THE WHEELS,AND BY THE TITTLE I THOUGHT I WAS GOING TO WATCH WHAT WAS INVOLVED IN PUTTING A SIX SPEED IN A C3 SINCE I HAVE A 2002 CAMARO 6 SPEED I WANT TO PUT IN MY 77,HENCE THE THUMBS DOWN FROM ME
Allan, this is part 4of the series. We cover the install across all 4 videos. Did you see the others? Here's the whole playlist: czcams.com/play/PLGV8X9X8baVizfPH6-qxNKrHmnGUAr81Y.html. The holes are to accommodate different bolt patterns with the same wheel.

Please stop with the blurry image which slowly becomes clear, so annoying.
Sometimes I just don't get it. Wanting the car to look stock with the newer radio yet not caring that it doesn't look stock with the Dakota gauges? Why not be consistent about everything? The motor, brakes, wheels etc. are all NOT STOCK and not STOCK LOOKING. There is nothing stock at all about this car so it just puzzles me but it's not my car so I don't care. It's just weird to think about how other people "think". When in truth, all cars are "stock" for about 15 minutes until you drive them off the lot. Then they become used cars with original equipment. A water pump needs replacing, and the car is no longer original and never will be again. After some years go by, the owner wants to make the car original, but it can't be done. Even if you hand paint factory codes on the rear end housing and try to duplicate what the factory did, it's NOT original. So, why not be honest and if you own the car, make the car exactly the way you want it and as comfortable and safe to drive as possible and who cares how "stock" it looks? I realize I'm alone in my thinking but oh well...
