Lake Speed's Ford C3 NASCAR Engine: Time Capsule of 90s Technology! (Dyno & Full Teardown)
If you watched the last video we did with Lake Speed Sr and Jr you saw us load up an old engine he had sitting in his former Winston Cup race shop for almost 20 years untouched! Lake has a 1993 Purex Thunderbird left over from his days as an owner driver that he briefly used in vintage racing in the early 2000s. He has not driven a stock car since then. We are going to refresh this period correct engine and Lake is going to get back in his old car at 74 years old!!

    This series is extremely awesome because it blends our love of history with building cars and tech stuff! Who was surprised by the findings of the dyno session? 😂 Merch link:

      This is my first time viewing this series and so far I really like what is being presented. I’m not familiar with the people involved other than Speed Jr. who’s obviously quite knowledgeable and intelligent. But the person asking all of the questions and I think is operating the camera too, is coming across as being a tad on the ignorant side. Is he deliberately asking dumb questions in order for Speed to answer them in a manner that the viewers can easily understand ? It would be hard to imagine that someone involved with the show is totally clueless about the topic. Despite the annoying distraction, I’m really looking forward to seeing the next episode. I understand why the Ford C3 heads are being referred to as old technology but there are several modern builds featured on IRglo that are using C3’s to their fullest potential and posting dyno results close to the magic 1000 horsepower mark. No power adders, single 4-V induction and all Ford engine !

      Love the hard core tech stuff! Btw at 11:40 you can see a plug wire arcing out, definitely part of the problem on the low power. Plug wires are probably 20 years old

      My Favorite subject I’m obsessed with building engines and making Horsepower and have been since I was 12 yrs old and had a slow go cart that I wanted to go faster lol the more of these old nascar engine tech videos the better it may be outdated by todays standards but they made power back then and seeing how and how they made them survive 8000 plus rpm’s for hours is always cool

  • Lake Speed, Jr.

    WOW! I'm truly amazed and humbled by all these comments. My Dad and I thank ya'll so much for watching, commenting and enjoying these videos. We are excited to be working with Mitch and Logan, and I can't wait to get this engine back together and on the dyno. Stay tuned!

      I raced Karts in the 70's and followed your father's career. Him winning the Karting World Championship in 78 was a huge accomplishment for us American Karters. It is such a Blessing to see you and your dad together. My family moved to Daytona Beach in 1978, so I got to see your dad in Daytona a few times. Listening to you explain tech shows you are a genius. I love your enthusiasm! Keep up the great work!

      @dan farris I know, I came all the way from New Zealand in '87, to see Bill and Bob, in Nascar and Pro Stock T-birds, kick GM ass...and trust me...they didn't disappoint !!! P.S, I think I remember they had oil squirters to keep the valve train cool allowing more RPM, or something like that !!

    • chevy james85
      chevy james85

      @EspeeKeith there’s two reasons why that is happening. 1 is cause the no ride height rule, which needs to be brought back, and setup. It’s a f1 style race now. The rules need changed to make the racing better. It’s not the car, it’s everything else in my opinion

    This series of videos are the best ever. You're the only one doing this and are showing an insight only that generation knew. It would be lost forever if you didn't travel down this path. Fantastic job and fascinating one of a kind video record you have created of old school NASCAR drivers, tech, team shops and racing history before it's lost to the ages. You know this stuff is good you can see it in your face, but I hope you realize what an important thing you two are doing as well to preserve history. LOVE these videos and thank you for your hard work and dedication. All your videos are great, but these are AWESOME!! Keep it up! :)

    This was REALLY interesting! I used to race dirt back in the 70’s and we had zero access to this kind of tech. ANY clue as to when part 2 comes out? I can’t wait to see what the end result is! The techs are also very engaging and not boring at all, LOVE hearing all the tech talk from guys that know what they are looking for and know how to modify it properly. This would have been a dream job for me 35 years ago keep ‘em coming!

    When I heard that number I was really shocked I did not think it was going to be that low. I love the way Lake Speed Jr talks not only is it very informative but he has such great energy and you can tell he truly loves what he does. I myself am a data nerd I love the information some of it I did know but a lot of it is new information.

    I was really surprised by the horsepower made by the C3 Engine, it was way lower than everybody expected. I can't wait to see what Lake Jr and PME can do with it on rebuild. Fingers crossed for 700+!!! Awesome content as always!!! BTW my wonderful wife surprised me and ordered my first SAW Tee!!! Thanks again guys.

    A point of contention... the early "Jack Roush" intake manifold are for the 6049 A3, B351 and C302 cylinder heads. These were Cleveland architecture canted valve heads (9 degree valve angle with 4 degrees of side cant) with raised intake runners which were raced in NASCAR 1983-89ish. Robert Yates had nothing to do with those heads, the pattern work was done by Alan Root, early port design was done by Bud Moore and later Roush.... The 6049 C3 heads on Lakes engine are a Yates design where it kinda shares the intake and exhaust pattern of the C302 but there is alot of valve train, port architecture and outer espc the Intake face/flange changes. The biggest thing Yates did on the C3 was remove the side cant from the intake valve, which made huge improvements to valve train stability at higher RPM.... in later revised C3L and C3H heads the valve angle was reduced to 8.3 degrees with no side cant and the valves position was shifted .060 towards the center of the chamber so a 2.180 valve size would fit in a 4.14x bore better. Cool video and tha engine should be easy to improve considering how mismatched it was.

      @Daniel Wilson I'm fairly sure I heard they (the Elliott's), expected it to blow up long before the finish line ! The other teams must have been all over NASCAR for a Bob Glidden-style weight break or such like !!!

      @Philip Mac Duffie … You make an excellent point that is often overlooked or not even understood by certain people that should know better. Bare head castings are typically as the name implies. They lack valves, springs and all of the required hardware needed for a complete head. Raw head castings are for skilled builders with access to a fully equipped machine shop to turn these head shaped blanks into functional heads. The critical areas like the ports and combustion chambers are unfinished so the builder can locate and shape them to suit his requirements. Definitely not a task for novice builders.

    That "Clover leaf" restrictor plate insert is just like the ones i saw back about 1990. the purpose of that center tube is that it is a resonance tuning tube. I know it helps the air flow faster in the outer tubes.

    Think about the valve springs sitting still for 20 + years, how thick were the head gaskets, how much friction did the rust in side the bore cause, and how much drag were on the rings, something to think about, we use a clever type engine in a drag car with those style heads ( Yates)@434cubic inches making close to a 1000 naturally aspirated, in an old pro stock car. Keep up the great work ‼️

    The "W" with the number on the front is an indication that the intake manifold came from Wilson Manifolds, Keith Wilson. Cup manifolds never got an ID plate, just a W and a job number. That thing was state of the art at the time.

  • Hugh O'Brien

    Being a cylinder head guy I’m going to be betting the beryllium copper seats are wiped out and not flowing any air. Back then everyone was stuck on .002 valve guide clearance and that would wipe out beryllium copper. They also used a bunch of seat angles on the intake and if one of those angles got wiped out from the seat width growing too wide the air flow would be reduced more than we can imagine. I also suspect those valve springs have given up the ghost to a degree. Then there’s pushrod deflection. Rocker Arms flexing like plastic. Just my bet. I’ve got a set of these heads still brand new.

      @Philip Mac Duffie agreed. We got the build sheets. The motor was last rebuilt in 2002, so it is more modern than the 1992 T-Bird it came out of.

      Philip Mac Duffie

      Those old jesel solid bodies are not floppy, they are heavy. I'm not going to.stand here and bump my chest or anything but a 90s cup motor didn't have 5/16 pushrods in it either. I think you are going to find weak springs, ring seal problems in those hazy bores, and valve seats that are just flat wore out. It's not like pro motor doesn't have more experience than most in old hardware. That is what they do. Those heads look like c302 era c3s not c3l as well. Cutiously it had one peice rocker Pads. I'm not experienced enough to know that an unrestricted c3l beats a c3/c303. But they look canted to me. A later head is not.

    Thanks for the vid! I think "tired" is the key word. Everything is worn enough to add up to a significant power loss. If you dont mind, when you do the tear down, check everything: rod length, deck height, bore size/ roundness, valve lift, spring pressure, ring gap, cc the heads and pistons to deck at tdc... all of that would be awesome to know how far from spec it can wear after 4? races. (On another note i was suprised to hear him add 5deg all at once, thats huge)

    Love the stories... like on the Dale Jr download. Lake said you could pump air in or out wink wink 😆. That ingenuity is what made the sport awesome I think, not this everyone has the same equal stuff like now. I was amazed with the oiling setup in this, something I didn't know.

  • Hue

    Fun fact about Lake Speed. When he won the Karting World Championship in 1978, he beat out Aryton Senna for the title. That's such an amazing accomplishment, to beat out an all-time great driver like Senna.

  • Battlestar777

    Thanks so much for your time to dig deep on this one. Lake Jr. is remarkable at explaining the processes of this investigation- can’t wait to see the next follow-up on this. I really love the fact that you found the Speed family, and they are willing to share so much of their time and resources with you (ultimately us ! ). I’ve found a whole new respect for that family and their racing heritage. May God continue to bless them (and you) on life’s journey. Thanks again. ❤️

Plenty of variables to deal with Head c.c. size , Head gaskets, I think your working with the Right man ( Lake Jr, ) when it come to the New rings and pistons choice for the freshen of the engine.

    I am amazed at the knowledge these guys have about the famous 351 Cleveland engine. Long after that engine was so popular, I worked in engine plant #1 at the Cleveland site.

    There were at least two different heads marked C3. Some of the early C3 marked heads were really C302b heads with side cant on the valves like a Cleveland. Later more common C3 were the Yates design without the side cant.

    I used to watch Nascar every week looked forward to it. I can't watch it at all now after about 3 years ago but I sure do enjoy this type of activity. And I'm looking forward to where this is going for everyone involved. Those places where the stains are in those cylinders where the Pistons set for 10 years or so I'm just wondering if there is some friction going on in those areas that's robbing horsepower I'm sure there is just not sure how much but that setting affects a lot of things like you all talking about. AgainPretty darn cool.

  • Tim Russell

    Just a quick observation here, but, when that engine was initially dynoed there was something going on at the top of the #5 wire where it attached to the spark plug. Was that spark arcing away or was that just a small flap of paper or something else flapping around there? It is really hard to see from my tiny little phone screen. I'm sure it wasn't spark arcing away or those guys would have caught it, but can anyone else see what i'm talking about? It was the left side of the engine on the very first spark plug(would be cylinder number #5 on a ford engine i assume)....probably was just paper or something flapping around but am just curious to know what that was

    • Stapleton42

      It was heat shield flapping in the wind!

  • ColdSmoke

    This video is absolutely awesome and thank you for sharing. Seeing inside one of these engines is a very rare opportunity. I'm wondering and even betting that the 114 octane was hurting performance quite a bit as they're simply wasn't the compression to utilize it.

  • Jamie Hess

    What is very informative is referencing today as being "modern" when compared to only 20 years ago. This shows how innovative engine designs moved from year to year. This leapfrogging progress really put the lower budget teams like Lake at a competitive disadvantage. This also shows how having a great driver like Lake could still keep a lower budget team head-to-head, make the bigger teams sweat, and still win races! This type of video is great work, mixing tech with very good explanations for the less experienced. The part about the McClure valve was gold (better vacuum or more air?)! The NASCAR engine design was locked into the track design. Did all sanctioned NASCAR tracks have the same steep angles?

    • Stapleton42

    This is gold Stapleton, I love this series of videos! In the 70’s and 80’s Lake Speed and Haddock’s karting adventures where an inspiration to me as a young racer, then followed up by Lake’s NASCAR efforts as a privateer. This peek behind the curtain is awesome, what a great family with a passion for racing still strong today. So genuine, open, and honest. Was surprised at seeing in previous videos that Lake still has the kart that he drove to the world championship sitting in his shop, along with a dozen other karts, and two engine Dyno’s lol. Excited to see what what Lake Jr has in store for this engine in the future.

    Just want to add my thanks for this video. I loved the first ones with Lake but seeing his son's enthusiasm as well is so entertaining. Keep on going with these type of videos. I'm looking forward to the next chapter of this series

      Our pleasure! We absolutely will!

    Great project. Be very curious to see what's inside that 385 series. I agree with the guy, it's just tired. However, it still does sound smooth and is hitting all 8. You might want to mention the difference between static and dynamic compression. Which of course has a lot to do with cam specs.

    Oh man. Lake Jr. What a cool guy. I love his enthusiasm about this stuff and the history of the machines of the sport. I could listen to him for hours. I was always a fan of Lake Speed. I just admired his privateer team and how he ran it. These two videos have been so interesting learned so much about his career. And so cool he still has those Purex Thunderbirds. As a scale model builder. I love to build accurate NASCAR models. And that car has been in my line up of To Do builds. Along with his Wynns Olds. These videos have answered a few questions I had about both of those cars. Side note. I came up with that Purex paint job 4 years earlier on a model car. I liked building "What If" race car models. Only difference was the number and it was a Pontiac not a Ford. So when Lake showed up with that car. I fell in love with it. I love this video series and looking forward to the next.

    Great video Mitchell and Logan i love how excited Lake Jr. Is to fix his dads old engine. The dyno number shocked me being so low i wonder if some parts are mismatched?

    • Stapleton42

      Low compression and worn out mismatched stuff probably!

    What a GREAT video -- very informative, as always!! My late father-in-law used to see me watching a cup oval race and comment that "they just go around in circles." I would explain to him that a lot of the modern-day street car technology that lets motors last 200,000-plus miles, and makes cars stop in a fraction of the distance that cars were capable of in the fifties and sixties came because of what guys like are in this video were doing in research and altering technology to make those engines and cars last 500 miles at those kind of speeds and RPM's! Lake Speed and his son are every bit as passionate about this as they were back then! Can't wait for the next part!

    If this was a 92 spec. This would have been racing against Davey Allison in the Yates #28 turning 9500 RPM that season.

    Suprised at the dyne results, learned a lot about the oiling systems too. Looking forward to Lake getting back into the car and his reaction to the refresh. Great stuff!!! Cheers!

    Your so lucky to hang out with all these guys. Most everything I work on is normal, everyday cars, all I ever wanted was to work on em, maybe someday, the closer I get to 40 the less likely it seems
