Years ago I read that Grumpy used micro switches on his shifter linkage to adjust the timing advance on his 327 '66 Chevy II (Grumpy's Toy) and was running mid 11s on 7-inch slicks. He was a trickster, cut from the same cloth as Smokey Yunick! I miss those guys, they were so much fun to follow. Horsepower Depot does basically the same thing, only with electronics.
@@danmyers9372 Actually, if you could somehow have this 70 Vette at the very first ever Pro Stock event, this car would have won easily while setting both E.T. and MPH during the Competition - not too mention No. 1 qualifier. Bill 'Grumpy Jenkins driving Grumpy's Toy (a 68 Camaro) turned a 9.99 at 138+ mph to defeat Ronnie Sox in the Sow & Martin Barracuda (a 69 model if I remember correctly). A mid 9's and lower car was the stuff racer's dreams were made of back then. They simply did not exist (not in any 'stock' class, that is).
I really enjoy the FAST series of racing. I can see how this would be so much fun. Even though I'm a mopar guy I do like the big block chevy cars you have and using ingenuity to pull every bit of power and speed out of these cars. and on those skinny tires too. Well done sirs.I know you'll keep knocking down those times. Best of sucess this coming year!
The F.A.S.T. vehicles are the baddest cars in history, period. Nine seconds on a 5 inch tire would rule everything back in the day. These cars are just remarkable with todays technology. Obviously we are getting 800 horsepower ice cars form the factory and 1000 horsepowered electric cars but these F.A.S.T. cars are just wicked. You and your dad have done an outstanding job learning and experimenting, keep going!!!!!
I’ve always been into street cars that are faster than they look, or than they’re supposed to be. This car is the best example of that I’ve ever seen. Job well done 👍
The amazing part in all this is found in how it re-enforces the idea of "no replacement for displacement". When people talk about how old school engines can't compete with the modern engines they forget that the old school engines are no more limited to exclusively using 50 year old tech than any new engine is. This car runs ONLY low 9s due class rules. Imagine where it runs with APPROPRIATE sized headers and exhaust, an intake that isn't mandated to be "factory appearance" and then the drag slick that can actually "Hook" without taking away timing for so much of the initial run. Mid 8s are merely the easily achieved, first stop, on the way to something absolutely unimaginable 1969.
God! THANKS for the in-car shot starting at 6:13 ! Brings back such good memories from my '67 L-72 Vette street racing days ! Watch that tach march right up to EIGHT GRAND, BOYS ! wHOOO HOOOOOOOO ! ! ! AND AWAAAAAY WE GO !
I work in the Marketing Department at Coker Tire and have always been so curious about how you guys make those Wide Ovals work so well. Thanks for sharing your information on the tires and all of the other hidden details about these FAST cars. Very cool.
"Make em FLOW, make em GO". I had a 71 LT1, nice car but the 67 L79 was more of a favorite for me. I always like the newer style of 68 to 72 vettes but the HP Drop started in 71 and continued to decrease. I think the 67 was still and always ill be the best year for the Vette's at least for me. Great video , thanks.
The 70 LT-1 with the 11:1 motor is a BEAST! the 71/72 smog motors lost quite a bit not only with the compression drop but, the 71 up "smog heads" dropped quite a bit of power as GM was frantically searching to reduce NOX emission levels for the 72 model year, combustion chamber quench between the early heads and the open chamber later heads cost quite a bit of mid range torque...That's kind of why you will see that 71 & 72 LT-1s were often speced with 4.11 gears to make up for the lost power with gearing...Ford and Mopar didn't emascualate their Muscle Car motors until 1972 . My 72 LT-1 with factory 4.11 gears ran 103MPH @ the Drags while my 70 LT-1 ran 107MPH with 3.70 gears....Big difference in the way they run and what fuel they like, even with mild timing that 70 LT-1 isn't happy on 94 octane pump gas, put race gas in it....It's quite a bit happier!
Man, when you cranked it & left it idle at the end of the video, that sucker sounds SO bad ass. You guys and your engine builder really know what you're doing. Great stuff !!!
I went to Bloomington Gold a couple of years back for the L88 celebration at the Indy Speedway. I'll always remember the sound those big blocks made going down gasoline alley. Thanks for sharing some of your speed tricks.

Nice video and awesome car! 700+ at the rear wheels, that is a lot of power. I would be happy with 500. You proved that 2½" tubing is not all that bad. I bet that roll cage stiffens up that car a lot. The factory frame is not all that strong. The bird cage section in the middle of the car helps. I redid the frame on my '70, sandblast, rewelded seams, painted. Apparently it needs to be reinforced in the rear section of the frame to handle a built motor, I found a kit that does that. Just a street car, no racing.
That car is absolutely perfect. The perfect street sleeper. I'd like to build one basically identical, but with less compression, slightly bigger motor, and add headers to offset the lower compression ratio. I believe he said at one time the manifolds cost it 100hp. So headers, 572, a bit less cam probably, and I wonder if a 4L80 would fit in there? Probably run high 9's with a streetable Vette. Awesome.

It's more about the mechanic's abilities to build & setup a car than it is about the brand. I went thru high school from 1963-1967. The fastest car anywhere around here was David Horn's 1963 409. He sold it and picked up a 1966 427 Vette. Then the fastest car anywhere around here was David Horn's 1966 Vette. There were other guys putting big money into Hemis & such that just couldn't get there.
I remember reading about this class when I was a kid and I was BLOWN AWAY that they were running 11's. Two of the only tricks that they "loose lipped" were a Hemi guy said taped a sandblaster nozzle on his fuel line and went to dinner to widen the inside diameter and one trick that a '69 Camaro guy did that I already knew about from the '87 Turbo T nicknamed "The Grey Ghost" that used to race Woodward. The RPO V75 "Liquid Tire Chain" option. I actually emulated that trick in my 4th gen with a junkyard Trailblazer washer bottle (it has two motors) and picked up 2 tenths using TracBite at an already good track on free 17" snow tires. I usually get the bye run when we have an odd numbers of cars. But this is an amazing video for those of us that wondered. It's kinda like you are telling us Santa isn't real though :)
Really impressive how you get these 1/4 mile times on stock tires with zero wheel spin. Just goes to prove you don't need monster drag slicks and thousands of horses to be quick. You also don't tear up as much equipment when the driveline is balanced. Do you think you will be able to get into the 8's on stock tires?
wow the stock IRS, I'm surprised it holds up so well under pressure like that. Make em Flow, make em Go. Run-in anything under a 10 is great, 9's are super.
Nice build 👍. It’s a beautiful ‘Vette for sure, and surely a blast to drive. And yet we are living in crazy times when an *actual* 100% factory stock car on factory tires can now gap this Vette without a single mod. Crazy times 🤔
really enjoyed this vid..........thanks for sharing your expertise and know how.....real car guys love this....the car really hooks up.....how many shops take thousands and do alot less....lol
Some of those 1969 Corvettes came with side pipes. I wonder if those would have improved the flow somehow just due to how they were routed to the side of the car and less bends?
lovvve the car! thanks for the overview, very informative. I've been kicking the idea of getting a Vette for my dad. This puts a C3 back in the picture.
Just imagine how FAST that vette would be with an effective exhaust and a 250 shot of spray or a blower. Damn nice and fast vette as I've said before and you gotta love that idle.
Yeah, the car is not fast because you saw a video on RUclips an decided what the problem is. Not everybody like loud cars and loud doesn't sound better. Fuckin' keyboard mechanics...
First, thanks for the walk through, I'm building a street/strip '75 and I was thinking about a small flair on the wheels..... maybe not anymore. BTW, it is getting expensive to put a 12 bolt inside the 10 bolts.... to the point that I might just go with a 9" IRS.... Second, you mention how much fun it is. What people don't know is part of drag racing is the 'hurry up and wait" - you spend lots of time int he pits or staging lanes. In the staging lanes its really a meet and greet car show. Meet extremely diverse people with all kinds of interest in cars - from pickup truck owners running their diesels to the '63 Pontiac running stock motor... Highly recommend you find your nearest track and head out especially during "test and tune" Don't be shy.
Hey do they let you run the Monzas with the 350? I looked at Stock Eliminator on NHRA, and it only looks like they only allow you to run the V6 even though the 350 was a factory option!
I could be wrong but I think they only had a 2 barrel carb. I'm guessing that would kill any advantage you gained by going with such a small lightweight car.
@@TheInsaneShecklador I cant find anything definitive that Anchors it down as only available for 2 bbl .. Interestingly, the 305 4 speed 1977 mirage hatchback is faster than any of the 5.7s by over a second who knows if that is a 2 bbl either?? There are tricks to get extra cfm though like running 2 PCV valves , reaming the venturi out etc etc .. The old heads could probably tell you about 20 more.. anyway
One thing he should tell those that don't know. Those aren't stock tires. They are stock appearing tires, made with a compound as soft as the stickiest drag slicks, and with very little tread depth. Probably even softer more flexible sidewalls to ease the shock on the tread. I'm not saying that there is anything wrong with all that. Back in the 70s we ran recap tires that had a soft compound and even what is known as sawdust recap snow tires. Real soft compound and sawdust in the rubber that would fall out as the tire wore to make little holes for traction in snow. But the soft compound on dry pavement would grip great, and would surprise the unknowing street race competition. He probably also has a very expensive soft hit torque converter to go with his ignition adjustability to keep from blowing the tires off and putting the power down instead of spinning.
Your tire assumption is 100 percent incorrect. They’re tires from Coker tire just like what anyone can buy. We talk about it in our latest video actually.
Not bad on street tires. Using the Holley EFI system would also allow Traction Control if it’s legal to use. I’ve been involved with NHRA Super Stock Corvettes since the early 1980’s which look very stock also. Of course, they can use headers and drag slicks up to 14.5 wide. Two of these cars that I know very well have been 8.50’s at over 152 mph at 3100 lbs. Biggest difference is the 1.15 60ft times due to the radial slicks.
Yeah it’s legal, useful to save a run, but traction control won’t make it faster. The corvette is a great drag car! I’ve seen a few super stocker corvettes back when we raced stock in our Copo Camaro. Corvette drag cars always look good!
@@HorsepowerDepot Don’t know if you remember Bernie Agaman from NJ he was one of my mentors along with Ralph Truppi. Bernie used to reset the National Record every race with a 1971 SS Vette. Once they allowed the solid rear end the rest is history. Great race car. Great job by you guys.
Question.. Have you tried or dyno'd Spin Tech mufflers such as their Pro Street or Super pro Street (6000 or 9000 series)? Here in Michigan we have found they are very close to Ultra flo in hp/torque much better than any Flo muff.
What size torque converter are you running ,obviously a small one to get those time,s The smallest they have is a 9 1/4. The power glide 7 1/2 torque converter would wind even quicker .I took my 427 out of my 69 COPO Camaro after I blew the motor ,I put 327 out of my 55 chevy tow car .It was 375 HP long block with double hump heads and Duntov 30-30 cam .I put a Edlelbrock high rise manifold on it after I took it out of my 55 .I had left the carb and intake and exhaust from the 55 .I could not afford to anymore after putting all my into my 69 Camaro that I put the rotating assembly from ZL-1 ,It was from a 430 inch motor with 3.43 bore and 4,44 stroke , I could wind to 9800 rpm with a 11" aluminum flywheel and forged steel clutch and clutch disc that weighed 26 lbs .When I put 327 with mods in my Camaro .I could wind it to 8000 rpm in less than 1/8 th mile .I may have been as quick as my 427 with small h78-15 tires I used for towing Camaro to the dragstrip .I used towing since could afford trailer .I put a 4.56 gear in my 55 to help me tow it easier ,It was around 60 to 70 miles to the strip one way .
Might have been said but with that exhaust being the biggest restriction is it specified in the rules if that's inner diameter or outer diameter? .7854 x that like a bore and find the extra you can get with 2.5 inner diameter vs outer diameter. Really cool walk throughs Man. Cool channel and excellent cars.
I always wondered about that much power with a Uni-body car, or even a fiberglass body and the twisting at launch. Maybe because you 'soft' launch them it's not an issue? I love this channel! If you're heading out to Norwalk anytime this year, let us know if you can... I'd love to watch and take some video of you guys. I'm a stones throw over in Akron. Thanks!
Love your channel. Have you ever made a pass with the vette running open headers, just to see? Or open headers and true slicks? What’s the ultimate potential outside the class rules, low 8s?
1st pass ever in this corvette was with slicks and it went a 9.28. We took the slicks off right after that. It would go an easy 8.90s with a good tire.
I've been studying this class and would love to build a car, but who knows if I ever will. I am just a fan of cars that look like cars, running down the track. I've read the rules, and there's one thing that isn't clear to me, or I missed it. If I take a base 69 Corvette and give it an L-88 makeover, is that considered a stock "appearing" L-88? I mean, you guys aren't taking real L-88s and ZL1s and modifying them, right? Sorry for the dumb question, but just curious.
Imagine taking one of those back to 1970 and seeing the look on people's faces when they saw it running 9's, lol
It would be close to Pro Stock times.
That would be priceless 😂

Wow! Love them cars! You have that Vette doing the dance! I'm going to have to check out fast sounds like it can be alot of fun.
So proud of you guys. I still have my blk/ blk 69 l88 orig numbers car. Love them. Been trying to find one to drag. I have 4 speed and it pulls so hard. I've watched your dad forever. Great job on vids.. cheers.Dan
Thanks for watching! Thats awesome you have a real L88! Things were bad ass right from GM!
@@HorsepowerDepot im up in ill, not far. I have huge collection of gm muscle, and g German, and new things . Some nasty buicks that Greg gessler did for me. I'd love to see the rides some time. Hit me up. Dan..
Just a killer C3!!! Absolutely love it!
Thank you for this info. I will come in handy my 71 stroker is at 430hp but needs improvement.
It's more about the mechanic's abilities to build & setup a car than it is about the brand. I went thru high school from 1963-1967. The fastest car anywhere around here was David Horn's 1963 409. He sold it and picked up a 1966 427 Vette. Then the fastest car anywhere around here was David Horn's 1966 Vette. There were other guys putting big money into Hemis & such that just couldn't get there.
Dayummm! That is almost unbelievable! Very impressive
First video of yours but not the last! Loving that big block Vette
Thanks!
Awesome! I also have a black 69 L36 but can’t touch yours. Great in-site.
Beautiful ,true Pro stock, not like 1970's, keep up the great work!!👍
You caught me with the Camaro tell all a week or so ago and here I am ready for bed watching the Corvette tell all.
I remember reading about this class when I was a kid and I was BLOWN AWAY that they were running 11's. Two of the only tricks that they "loose lipped" were a Hemi guy said taped a sandblaster nozzle on his fuel line and went to dinner to widen the inside diameter and one trick that a '69 Camaro guy did that I already knew about from the '87 Turbo T nicknamed "The Grey Ghost" that used to race Woodward. The RPO V75 "Liquid Tire Chain" option. I actually emulated that trick in my 4th gen with a junkyard Trailblazer washer bottle (it has two motors) and picked up 2 tenths using TracBite at an already good track on free 17" snow tires. I usually get the bye run when we have an odd numbers of cars. But this is an amazing video for those of us that wondered. It's kinda like you are telling us Santa isn't real though :)
Looks like a lot of track prep - still an incredible ET but it wasn't dry asphalt.
Tell me, do you think it was WET asphalt???
@@milojanis4901 No Milo - track prep - I'm suggesting it would be be very difficult to run 9.37 on dry asphalt.
Really impressive how you get these 1/4 mile times on stock tires with zero wheel spin. Just goes to prove you don't need monster drag slicks and thousands of horses to be quick. You also don't tear up as much equipment when the driveline is balanced. Do you think you will be able to get into the 8's on stock tires?
You realize that thing is making over 800 Hp at the crank?….that’s a monster engine 😯
I believe 8s on the stock tires is going to happen soon, might even happen this coming season...
@@HorsepowerDepot my dad has a original open chamber l88 in a 63 corvaire thats been altered. It is indeed insane the power those engines make.
@@chrisvig123 - I believe his point was, getting that much horsepower to the ground is an art.
@@HorsepowerDepot It's all on the exhaust right?
Awesome Corvette love the series that you racing in keep them great videos coming
wow the stock IRS, I'm surprised it holds up so well under pressure like that. Make em Flow, make em Go. Run-in anything under a 10 is great, 9's are super.
Nice build 👍. It’s a beautiful ‘Vette for sure, and surely a blast to drive. And yet we are living in crazy times when an *actual* 100% factory stock car on factory tires can now gap this Vette without a single mod. Crazy times 🤔
As a painter, I would like to say the paint and bodywork on that Vette is outstanding!... Do you guys have any events scheduled in Ohio?
Thanks! A good friend did the paint and body work. We will be racing at Summit Motorsports Park in Norwalk Ohio Aug 25-28
@@HorsepowerDepot Awesome! My son and I race there. We'll be there.
Great! Make sure you come find us and say hi!
This Corvette is quicker than the original Pro Stock cars from 1970, FIFTY-TWO YEARS AGO!!! OUTSTANDING!!!
Totally down to earth dude. Sweet built
Thanks!
Impressive car! My uncle has a 69 L88 he bought new. Sadly he doesn't want to part with it, lol!
really enjoyed this vid..........thanks for sharing your expertise and know how.....real car guys love this....the car really hooks up.....how many shops take thousands and do alot less....lol
Great stuff, enjoying binge watching to catch up, new subscriber!
Awesome! Thank you!
Want to see a Corvette like mine. And especially that USA Corvette
Some of those 1969 Corvettes came with side pipes. I wonder if those would have improved the flow somehow just due to how they were routed to the side of the car and less bends?
I don't know about the time but them side pipes looks cool
The factory side pipes hurt a lot of power. The muffler isn't a very good design.
I always remember them making 560 with headers.
Good video my father passed I have his 68 stingray just had my new born son were gonna rebuild his car
Love seeing cars get passed down to family, getting fixed and getting back on the road!
Great content. This should help a lot of people step up.........Thanks!
lovvve the car! thanks for the overview, very informative. I've been kicking the idea of getting a Vette for my dad. This puts a C3 back in the picture.
C3s are pretty affordable compared to other cars of the same years.
dang, you can about figure the cam specs by listening to it😊. very nice sir!
Nicely done you got my respect in Building Street Race Cars 👍
There is a white Fox coupe that runs high 7's with the 5 spoke ponys and street tires.
Not in the FAST class he isn't. They have restrictions.
This car is amazing!! Beautiful inside and out, extremely fast, and looks stock!!! Love it!!
Found your channel last week and love it. I LOVE AMERICA 🇺🇸
Thanks for watching! USA!!!
Would you consider flowmasters hushpower 2 a horsepower gaining muffler? They claim it to be and I don’t know if it is a truly straight though or not.
You wouldn't normally think of a Corvette as a sleeper but in this case, yea!
Just found your channel and I love it.
Thank You!
Super cool. Everything you do is cool
Awesome cars and it is very cool that you are sharing info. The creativity and ingenuity is impressive! Nice work.
Thank you very much!
Just imagine how FAST that vette would be with an effective exhaust and a 250 shot of spray or a blower. Damn nice and fast vette as I've said before and you gotta love that idle.
Yeah, the car is not fast because you saw a video on RUclips an decided what the problem is. Not everybody like loud cars and loud doesn't sound better. Fuckin' keyboard mechanics...
@@StoicaVladIoan loud=power. Power=better. You literally sound like an idiot. The fastest cars on the planet are open exhaust.
great video thanks for the nod to the slower cars.
Which of the Hemi cars are your closest competitors? Those cars are a good deal bigger than the vette but do transfer power well to the rear.
First, thanks for the walk through, I'm building a street/strip '75 and I was thinking about a small flair on the wheels..... maybe not anymore. BTW, it is getting expensive to put a 12 bolt inside the 10 bolts.... to the point that I might just go with a 9" IRS....
Second, you mention how much fun it is. What people don't know is part of drag racing is the 'hurry up and wait" - you spend lots of time int he pits or staging lanes. In the staging lanes its really a meet and greet car show. Meet extremely diverse people with all kinds of interest in cars - from pickup truck owners running their diesels to the '63 Pontiac running stock motor...
Highly recommend you find your nearest track and head out especially during "test and tune" Don't be shy.
The car is beautiful and really fast!
Excellent commentary, thanks, ted.
Hey do they let you run the Monzas with the 350? I looked at Stock Eliminator on NHRA, and it only looks like they only allow you to run the V6 even though the 350 was a factory option!
I could be wrong but I think they only had a 2 barrel carb. I'm guessing that would kill any advantage you gained by going with such a small lightweight car.
@@TheInsaneShecklador I cant find anything definitive that Anchors it down as only available for 2 bbl .. Interestingly, the 305 4 speed 1977 mirage hatchback is faster than any of the 5.7s by over a second who knows if that is a 2 bbl either?? There are tricks to get extra cfm though like running 2 PCV valves , reaming the venturi out etc etc .. The old heads could probably tell you about 20 more.. anyway
Nice Vette!
One thing he should tell those that don't know. Those aren't stock tires. They are stock appearing tires, made with a compound as soft as the stickiest drag slicks, and with very little tread depth. Probably even softer more flexible sidewalls to ease the shock on the tread. I'm not saying that there is anything wrong with all that. Back in the 70s we ran recap tires that had a soft compound and even what is known as sawdust recap snow tires. Real soft compound and sawdust in the rubber that would fall out as the tire wore to make little holes for traction in snow. But the soft compound on dry pavement would grip great, and would surprise the unknowing street race competition. He probably also has a very expensive soft hit torque converter to go with his ignition adjustability to keep from blowing the tires off and putting the power down instead of spinning.
Your tire assumption is 100 percent incorrect. They’re tires from Coker tire just like what anyone can buy. We talk about it in our latest video actually.
Fast sleeper baby..damn what a launch
That is a work of art.
Not bad on street tires. Using the Holley EFI system would also allow Traction Control if it’s legal to use. I’ve been involved with NHRA Super Stock Corvettes since the early 1980’s which look very stock also. Of course, they can use headers and drag slicks up to 14.5 wide. Two of these cars that I know very well have been 8.50’s at over 152 mph at 3100 lbs. Biggest difference is the 1.15 60ft times due to the radial slicks.
Yeah it’s legal, useful to save a run, but traction control won’t make it faster. The corvette is a great drag car! I’ve seen a few super stocker corvettes back when we raced stock in our Copo Camaro. Corvette drag cars always look good!
@@HorsepowerDepot Don’t know if you remember Bernie Agaman from NJ he was one of my mentors along with Ralph Truppi. Bernie used to reset the National Record every race with a 1971 SS Vette. Once they allowed the solid rear end the rest is history. Great race car. Great job by you guys.
What a great job, I tip my cap at you.
I seen the title and had to click. Very impressed.
Thanks for watching!
Question.. Have you tried or dyno'd Spin Tech mufflers such as their Pro Street or Super pro Street (6000 or 9000 series)? Here in Michigan we have found they are very close to Ultra flo in hp/torque much better than any Flo muff.
I have not messed with any of those. Might have to look into that. Thanks!
That's a beautiful Vette! C3's have always been my favorite body style. What's the 1/8th mile time's if you don't mind my asking? Good video 👍🏻👍🏻👍🏻
Do you know anyone that runs the Spin techs or what have you heard about their performance?
I really appreciated the 4 arms trick 👍
What size torque converter are you running ,obviously a small one to get those time,s The smallest they have is a 9 1/4. The power glide 7 1/2 torque converter would wind even quicker .I took my 427 out of my 69 COPO Camaro after I blew the motor ,I put 327 out of my 55 chevy tow car .It was 375 HP long block with double hump heads and Duntov 30-30 cam .I put a Edlelbrock high rise manifold on it after I took it out of my 55 .I had left the carb and intake and exhaust from the 55 .I could not afford to anymore after putting all my into my 69 Camaro that I put the rotating assembly from ZL-1 ,It was from a 430 inch motor with 3.43 bore and 4,44 stroke , I could wind to 9800 rpm with a 11" aluminum flywheel and forged steel clutch and clutch disc that weighed 26 lbs .When I put 327 with mods in my Camaro .I could wind it to 8000 rpm in less than 1/8 th mile .I may have been as quick as my 427 with small h78-15 tires I used for towing Camaro to the dragstrip .I used towing since could afford trailer .I put a 4.56 gear in my 55 to help me tow it easier ,It was around 60 to 70 miles to the strip one way .
Might have been said but with that exhaust being the biggest restriction is it specified in the rules if that's inner diameter or outer diameter? .7854 x that like a bore and find the extra you can get with 2.5 inner diameter vs outer diameter. Really cool walk throughs Man. Cool channel and excellent cars.
What about the fuel system? Are you running a mechanical or electric pump? Can you say which pump you are using?
I always wondered about that much power with a Uni-body car, or even a fiberglass body and the twisting at launch. Maybe because you 'soft' launch them it's not an issue? I love this channel! If you're heading out to Norwalk anytime this year, let us know if you can... I'd love to watch and take some video of you guys. I'm a stones throw over in Akron. Thanks!
August 25-28 we will be in Norwalk for the NMCA event.
This seems like a fun class
This is a tough class to run in at this level since there is cubic dollars and a lot of R&D involved.
Love your channel. Have you ever made a pass with the vette running open headers, just to see? Or open headers and true slicks? What’s the ultimate potential outside the class rules, low 8s?
1st pass ever in this corvette was with slicks and it went a 9.28. We took the slicks off right after that. It would go an easy 8.90s with a good tire.
This video is sooooo cool!!!
Thank you so much!
I've been studying this class and would love to build a car, but who knows if I ever will. I am just a fan of cars that look like cars, running down the track. I've read the rules, and there's one thing that isn't clear to me, or I missed it. If I take a base 69 Corvette and give it an L-88 makeover, is that considered a stock "appearing" L-88? I mean, you guys aren't taking real L-88s and ZL1s and modifying them, right? Sorry for the dumb question, but just curious.
Gorgeous ride
