1967 427 Corvette Picks Up 1 Second In the 1/4 Mile! THEN We Add 40 MORE Horsepower! Find Out How! 

I absolutely love that Corvette. I change my sbc valve springs at 110 on the seat. I shim my new springs 10% higher than manufactured specs due to spring pressure loss after a few heat cycles.

Much MUCH better! Way to go guys.

Man I love watching you drive. My Dad shifts exactly like you do and that's how I was taught too. Freaking love it.

Man that tone through the full exhaust is beautiful...bb ftw 👌🤘

I love watching you guys race. Can’t believe how quick your cars are with those skinny bias plies!!!

Growing up in the 70's and early 80's plus realizing that an automatic is the way to go for drag racing, there's just something about the sweet sound of a big block Chevy and a 4 speed it brings back so many great memories riding with my uncles and grandfather back in the day! Chevelles, Novas, Camaros, and even an orange Road Runner, so cool another great video!

Another awesome Video !! Great Job .. 👍

I ordered a New 67 Vette in late 66. Got it in February 1967. Special Order Marine engine with gear driven cam. Advertised HP 435. I changed the stock mufflers to Corvair Turbo mufflers, Took it to Nickey Chevrolet in Chicago, where Dick Harrell was in charge of their performance Dept, had distributor recurved & that was all that was done to it. Turned 12.83 in the quarter @ 118 MPH with stock red line tires. Later with Radial tires it turned 12.61 @ 119 MPH. From what I was able to find out, ONLY 3 corvettes came out of the Factory with the gear driven cam engine. The general manager of Chevrolet owned one just like mine, Goodwood green with Saddle interior, but his had sidepipes, mine didn't Sure wish I would have kept that car. Traded it off for new car & pickup two years later in Forest Park Georgia. Have been kicking myself in the ass every time I think about. Vette had 3,70 gears & would run 160 MPH by speedometer, but well into the Redline.

Wow guys nice job ! I'm seeing 11.80"s!

That green vett rocks. Looks. Like. That. Would be a blast. To drive. Keep. Slamen. Gears. Love. The vids

Gorgeous car and love the way you guys squeeze power out f these motors just tweeking them.

Love these vids, I agree, you should do a few runs with this ol gal... nothing personal Ryan.

Wow that thing is brutal on street tires, gotta like that 4 speed for fun factor.

Yee Haw , watching you guys tear up the back roads while using the " butt dyno " takes me back to my youth !

Thank You for another cool video , I miss going for rides in my friend '66 since he sold it a few years ago.

you guys are awesome , would like to bring my 71 LS5 there for some work.

Wow, I can't believe that Muncie is still together. I use to break them with a small block.

Keep the Videos coming Love them!

Sharp looking GMT400 sitting outside the pole barn. Vette’s not too shabby either.

Bad ass car . Love it!! Do not break it!!!

Yeah best looking vette ever

Old cool racing 🏁 😎

Such cool racing! Wish they would bring it down south.

Sounds like you guys need some Rhoads Lifters .. The kind that get through tech but add an extra .20 - 30 thou lift when the oil pressure comes up ;) and a once of those Mid Valley face plated boxes

Real sweet

Beautiful car! My SLK could give him a run but that V-8 sound is sweet music.

I had a 68 427 three carbs on it but the guy I got it from took the three carbs off and put a racing three barrel on it it ran good I was young when I had it

Awesome

I love this car! I couldn't really tell if the clutch was slipping or the tires spinning when you hit 2nd. I'm guessing the tires were spinning as it looked like the car was moving around some. ??? At any rate I'm excited to see how it goes at the next race. Keep up the good work!

good Job

More sidepipe questions. Have you ever tried aftermarket/custom fabbed mufflers for sidepipes or did you just go straight to full exhaust? Also how much power difference is there in a factory stock rear mount muffler va what is on the car now?

watching beginning of vid I was about to ask if he was burning out or if second was slipping..lol

Good set of roller rockers would go fare on that vett..

What shifters are you guys using, Hurst super or longs great videos!

First time I ever seen an old stingray treated like a foxbody mustang

Nice car. Get some fender covers.

Hi - great video - what HP do you think the engine would make at the crank, if it is making 403 at the wheels?

Love these vids and the continued upgrades & fixes! Working with a dyno would be absolutely a kick in the A. -What are you using for a timing light? I've seen that shape in the now defunct Ferret line, MSD line, and Cornwell. I've never seen that color. Does it have a name and number on it?

Did you choose to run a six pack set up, or is it due to the class you are running?

This is really interesting. I have an 2008 ls3 a-6 convertible. 3175 lbs . Shifts at 6500 stock. I hear they dyno at 390 hp. I put kooks headers and 3" pipe all the way back to the mufflers. So maybe 415 rwhp. It takes off slow because of a stock converter and 2:56 gears. 1.918 60ft. Then it runs good to a 11.80@121.1mph. I just need a stall converter to get the car to a 1.6/1.5 sixty foot and low 11's. Pretty close to the 67 427 as it's running now. I wonder what the green 427 vette weight is? Can't wait to see your next vid!

I can not find an update to this on your channel, what did the car run?

What mufflers are you using?

Oval or rectangle port heads?

At the wheels...fyi...I was playing with these before you were born.

Lol. My 22 Explorer King Ranch runs that with just a tune.

What did you do to the munchie to make it live through those shifts….

I was just wondering when the last time a slipping clutch repaired itself 😮

I’m located about 30 minutes from your shop. Do you tune FiTech efi? Cost?

2nd gear clutch major sliped seemed to heat up and gggrab in 3rd lil bit d put a new pressure plate and 2 disc clutch in it that one is heating up flywheel might cause4 cracking

Goodwood green

Be careful with that clutch. When it does that "fix itself" a little while later it'll scatter itself. Been there, done that.

Hi, interesting video, so that looks like the 390 HP version of the 427 not the 435 with the solid cam and rect. heads? That should have a spring pressure of 300 with good stock springs. 5500 rpm peak sounds about normal and 6 grand sounds beyond peak with that stock cam which i think has than 500 lift. Rules allow 12.5 compression but requires stock cam? Is that FACTORY grind stock or similar? In 1975 i built a 67 Camaro Yenko clone so it had a 427/425 with the solid cam and rect. heads. I had a ZOOM BORG and BECK pressure plate with a street/strip disc, was like leg pressing 400 pounds but amazing engagement VS the diaphragm PP. Excellent time BTW. 110 pressure sounds LOW especially for aftermarket

Any plans for more content on the 4 door Nova?

My dream car

What does that vette weigh? Guessing around 3000# ?

Are you guys in Michigan? Nice toys btw!

Wait a sec. Back up.. tell me more about how I can get 30hp without my side pipes! Was that with stock manifolds to side tubes? Or long tube side headers like mine?

Is this an oval port head?

which App for GPS MPH??, so hope yer clutch is good yet. I am wondering why not a dual disc clutch?

Dumb off topic question. I have a '65 396 that revs to 7,000 easy. Which is nice. But it eats up a v belt in under 20 miles. Have to tighten it every pass because it's too loose as the rubber shreds away like a tire being burned out. I underhood smells and looks like a smokey burnout. Is it the big box store China v belts? Is there a quality brand? What pulleys do you run? Stock? Deep groove? underdrive? big alternator pulley?

Next drive camera on the back.

Was gonna say the clutch was slipping badly in the opening shot.

what fuel you running in this 67?

Need a new clutch

is that engine like old wine its get better whit age

You need 355 s

12.5:1 compression? Wow!! Not a pump gas car for sure.. There ought to be a pump gas class. That would be cool.

Still won’t hook unless you’re on drags or drag radials. Spinnin ain’t winnin.

Stock BBC heads didn't flow that well... especially 396 ones...

those springs have an installed height spec. if they aren't at the correct height they won't have the correct pressure.

You're not factoring in the rocker ratio when you measured the seat pressure. ie 100lbs indicated is 170lbs actual. ( 1.7 rocker )

Man, those factory side pipes are junk, 30 hp robbed 😅

I wouldn't bring any car to these guy's shop. Too disorganized and clueless.

I gotta find me 67 coupe

Looks like you need to stick to automatics. You’re definitely not Mr. 4 speed. 🤷🏻‍♂️

Can't drive a stick

Unessary abuse. No skills.

Did Ed sell the Yellow Camaro? Nice motor for the Vette. 🚥
