- 1971 Pontiac GTO 455 H.O. vs 1971 Buick GS 455 (Pure Stock Muscle Car Drag Race)
Featured are two phenomenal cars. In one corner, the 1971 Pontiac GTO. But not just any GTO, this one is packing the big-dog 455 HO. What an absolute monster. Its opponent is no slouch, though. We're talking about a 1971 Buick GS455... but like the GTO, this isn't just any run of the mill GS455, it's a Stage 1 package. I imagine both cars are a relatively comfortable ride, and of course very quick. Make sure you pay attention to the original MSRP for these cars... they weren't that cheap! Yes, both of these cars were built at the end of the muscle car era and have lower compression ratios (around 8.5:1 for both), but I think their power will still surprise you. Both cars are well maintained and I thank the driver's for bring them out. Who do you think will win? Both of these cars are featured in the Pure Stock Muscle Car Drag Race series.
Remember, both cars participate in the Pure Stock Muscle Car Drag Race series, so please check out their website: www.psmcdr.com

Two of my favorite muscle cars... comfortable and quick! I do have to say I'm not sure if this Buick is a true Stage 1, but it is reported to be built to Stage 1 specs (345 horsepower). Thanks!
I thought the Buick would win a 1/4 mile based on the 3.73’s vs the 3.31’s.
Not to mention it's a little big lighter and has better low end torque. Thanks for watching!
Stage 1 specs were underrated, actually around 400hp for '70 375hp for '71
MrBluzhound most likely would’ve been door handle to door handle with the same rear ends. (3.73’s)
Throw in a Olds W-30 for the perfect trio.
Im not complaining but it's better when you post the time rather than enlarge the time boards still hard to see!
I swear cars from that time that came stock had nicer interiors than modern ones sigh
No way. Today's cars are nicer, designed better, safer, faster and with much better build quality.
We love old cars for the nostalgia and memories.
That Buick wasn't called the Hemi killer for nothing
I love all the GM A-body cars from '68-'72.
I rank the GM A-Car in order:
1) Buick Syklark GSX Stage 1 455
2) Chevrolet Chevelle SS 454
3) Oldsmobile Cutlass 4-4-2 W30 455
4) Pontiac Tempest GTO 455
Back in the early 70's I had one of the infamous 1970 Buick GSX stage 1. Mine was the Saturn yellow with the flat black hood and Tach on the hood. It was a true muscle car that kicked some serious butt. I even blew the doors off a few Hemi's. The GSX was known for it's nickname of Hemi killer. I wish I still had that car to this very day.
I encountered one just like yours on the freeway here in L.A. back in the eighties. I pulled up next to him in my 383 Roadrunner. He wouldn't even look over at me. I guess he felt like his Stage 1 GSX outclassed my run-of-the-mill 383 Roadrunner . . .
Buick acronym, best use is Corvette Killing. B U I C K.
john jenkins hey what about a 1970 mustang boss 429 can the boss take out the king or not also a 1970 Shelby gt500 or a 1971 boss 351
@@AlejandroP1980s gsx beat the scj eliminator that's a fact,so I'd say yes it would win..
Don’t we all?
12’s with a 8.5:1 compression ratio engine.
The torque that these cars made shakes my bottom just from watching the video.
this here is what true American drag racing is all about! 🇺🇸😎(🔧🧤)
😎
Buick Stage I 455 , awesome car .
Those two sound so perfect ran next to one another! That was muscle car harmony😊
Geeked out a bit over these cars...just fantastic lines, simple, clean but bold, they look like they can still handle todays roads in comfort and style. Thanks for this video!!
Very true, these cars are still great to drive every day... that's not something you can say about all muscle cars!
My dad sold Pontiacs when the first high performance GTOs hit the lot. He talked the owner of the dealership into letting him take a couple of GTO's out to the local drag strip. He was beating people in custom cars with Stock GTO's off the lot with the window sticker still on it. He did "Win on Sunday and Sell on Monday." He said Monday morning some of the people he met at the drag strip came into buy a GTO.
Both cars ran in the 12's each time. That's impressive for low compression models.
I had a rare 73 Buick Century with bench seat, and special order 455. Not as fast as these, but very rare w/455 emblem in grill. Love all of these.
Sweet..I found a 74 GS 455 a few years ago, all rebuilt.....it is a strong runner....built to high compression specs , cam and headers...not mint- lot's of patina.
I had a ‘73 Grand Sport with the 455 Stage 1 mill. I installed a Kenne Bell cam and a set of M/T repro Super Scavenger headers and that car surprised a few unsuspecting drivers back in the ‘80’s.
Really nice channel you have going on hear CAZ, looking forward to watching
all of your vids, Thanks for posting these up.
I appreciate you watching! I have a lot more to come!
I bought my first car when I was 16 in the summer of 1982. A 1971 Buick GS. Lucky I survived with all that power at such a young age. Something special about your first anything let alone a car like that. Wish I still had it but it was gone by late 1985. One picture & a lot of great memory's is all I have left of it
Races like this were a common site on US 31 S. on Indy's southside from the late 50's to the mid 70's. I know street racing is dangerous and wrong but I sure miss those days. Cars that used to be commonly seen on the streets are now rare, high dollar collectables.
Lived in greenwood 90-92
May have been dangerous, but definitely not wrong if you were smart about it!
@@keithbalke6352
Been back lately?
Had three buick skylarks and my ( converted) 1970 Buick 455 with a x pipe 3in. Exhaust was by far the most enjoyable car I ever owned!!! It had the 1970 non stage 1 engine but MT edelbrock full headers made up the difference! It had a cam out of Alabama (hydrolic, not tapped set mechanical) with I self ported the heads) and an edelbrock 800cfm carb.....pretty simple but my car was an ass kicker!!! Ran 10s at Thunder Valley Oklahoma every time I prodded the beast 7 miles from my home 7 miles away at Lexington Oklahoma.......won lots of beer money from that car and lots of memories! Sold it at the track 8 months later. Made a lot of money on that deal but wished now I hadn't done it........loved my black evil Shark skylarks (it had a stage 2 hood scoop and rear spoiler, rocking a set cobra 11 on. 500 series wheels and a 4 link Art morrison rear suspension on coilovers)......we bad, we bad!!!!....thats the best time of my life and I HATE MY EXWIFE FOR MAKING ME GET RID OF MY BUILT CAR......FUCK HER AND DIE BITCH!!!
Had a '70 Skylark back in the day, with a Buick 350 in it. Bone stock except for the exhaust system. The previous owner had duals and glass packs put on it. Man, did it sound GOOD!!
Sierra - the Skylark 4 Bbl engines made 310 HP that year. Even the 2 Bbl 350 cars had allot of torque.
That buick is bad ass.
Good job bro i new you could do it!!!
71 vs 71
455 vs 455
I'm not surprised at the outcome. GS455's were beasts back in the day, and they surprised many at the stoplight drags
Can a 1969 gto judge 400 RAM Air V beat Buick stage 2
@@AlejandroP1980s Not sure, but I don't really count cars like those, as there was only a handful ever made
GTO driver was sleeping in the lights. Both rounds he got beat off the line bad.
@@Hobodeluxe960 GTO's were vastly overrated, they were mid-tier musclecars
@@justsumguy2u yeah I know, I bought a 1968 GTO back in 76 , one of the rare early ram air models
I'm pretty sure that 13.38 Motor Trend number for the Stage 1 was the 1970 car, but still a great matchup!
True ... neither of these cars ran 13's in 1971. No musclecar did in 1971. Smogging musclecars beginning in 1971 really hurt them.
Awesome channel for muscle car fans to geek out on. Excellent!
Awesome video..I must have missed this one. I try to watch them all..2thumbs up thank you.
Badass Buick to the front!
I owned a 1971 GTO Judge. Greatest muscle car ever built. I was young and dumb and sold it only owning it for a couple of short years. My biggest mistake I have ever made.
"Wouldn't you really rather have a Buick?"
Yes!!!
Hell yeah, every time, anytime, and every way over a Goat.
No ill take the goat any day
Love it , just like the good ole days again !
2 of my favorite cars ever. Had a gs400 convertible years ago. Someday I'll have a gto so I can say will have had both. Loved that Buick. Loved this video, thanks!
Thanks for watching! I actually have a video of a GS400 convertible coming in the future!
Jason - You have great taste in cars! Many memories of GS convertibles here too - My brother had 69 GS400 convert, and buddy had a 70 455 Convert right around the same time....it changes your life! Many Buicks later, I have a 74 GS 455 now....It is a Howitzer canon with windshield wipers - just like the old Gran Sport ad in 1965...
@@gt-37guy6 I'll never forget, the car was bought new for a business owners daughter for college. Way to much car for her... sky baby blue, white top, white leather interior... the chuckles and snickers at red lights from other muscle car owners, til the light turned green. The giggles and chuckles usually turned to anger... at the same time we owned that, my brother owned a 71 formula 400 firebird. 4 speed, had a crane fireball 2 cam... the gs would walk away from it. The memories of that buick... I'll have another some day...
@@CarsAndZebras please let us know when !
@@jasonkoster3102 - The first time my friend let me drive the 70 GS455 a Chevelle pulled out right next to me....We looked at each other at the same time an both floored it....The Chev was 5 or 6 car lengths behind me in about 6 seconds, my jaw dropped! It was light metallic blue too, and was a parade car for a local politician when new. Someone put a 750 Holley on it and an 8 Quart oil pan.....we used to race motorcycles with it! (But - motorcycles were not all that fast in the early 80s!). The 69 400 was very strong too, but not the wallup of that particular 455. At highway speed it would spin some tire on kickdown to 2nd!
The Buick GSX was the one to beat.
This channel should have many more subscribers than it does.
My first car was a well used 1971 Pontiac LeMans T-37 with the 350cid and 350thm trans with bench seat. I wanted a GTO so bad but I was a poor ass kid. Still, gotta love your first!
John - Very cool...Had a 72 Lemans Gold with GT stripe, I think it was close enough to being a GTO, I am not sure I would have lived had I had twice the HP! The 350 2 BBL was rebuilt and super tight...she dusted quite a few crappy Chevs in the day. I threw on a huge quadrajet and intake from a Bonneville 455, the top speed went from 110 to 128 MPH for a $ 50 swap and 90 minutes of wrenching....!
Had a ‘72 Olds Cutlass with a 350 2bbl. Same basic body as both but the exterior and interior details were all different. It was a special car for me. I had lots of adventures in that car. Had to get rid of it because I needed a 4 door for work. It was pretty rusted by then but I still had trouble parting with it. Loved that era and those cars.
Parallel experience here, mine was a Supreme 4 barrel....Gold with missing white vinyl top...I found some GTO buckets for it. It was a great car....it would just hum...man she was smooth and would hit 128 MPH. I ended up putting in a TH400 transmission from a Grand Prix, and it was capable of nice crisp 2nd gear rubber....just enchanting....shifted into 3rd gear at 85 mph when floored on the highway. What great cars!
Nice match up. Fine cars. Thanks
The Buick sure does not appear to be a Stage 1. The Stage 1 had Stage 1 fender badges (not 455), and also had a Stage 1 decal on the air cleaner lid, plus chrome valve covers.
Yep not stage one.. imagine if it was LOL
You are correct, read the pinned comment that was posted a few weeks ago. Unclear if it's a Stage 1, but engine built to Stage 1 specs
@@CarsAndZebras Are you sure that it was built to Stage 1 specs? I mean is there actual evidence and or proof of that because it seems to me if it was built to stage 1 specs that Pontiac would have been toast. The Buick engine is a vastly superior much newer design. I mean that Pontiac's engine's roots go back to 1955 and that Buick's engine's roots go back to only 1967. In 1971 it was still only a 4 year old design! Yes, it has it's predecessor's bore centers but that's all. So we are talking about a 12 years newer design and that was a very big 12 years at that. There were a lot of advances in engine design made during those 12 years. If you don't believe me, compare the "new" 1956 AMC V8 against it's 1966 replacement. The Buick big block is so good that it is 1 of the only 2 GM engines that routinely end up facing the Hemis in the final rounds of these types of events.
@@lilythomson881 - That's what the owner reported. You have to remember, these cars aren't truly stock. The Pontiac started life as an HO (so already very capable) and then "Pure Stock" allows you to increase compression by 1.5 points... which the Pontiac owner has done. Think about it, the Pontiac only came with around 8.5:1 compression and made some pretty crazy power. You increase that 1.5 points and it's a monster. Also remember, they have to run factory appearing tires. In the Buick's case, you have a ton of low end torque, but it's hard to put that down on skinny tires.
@@CarsAndZebras All very true.
Thanks for the vid! Cool match up. Very close races! Just goes to show compression isn't everything.... These cars are running 1970 high compression et's but their mph's are down.... The torque is there but the hp is mia.
No problem, just stay subscribed and hit the like button and I'll keep posting them. Very true, great torque from these engines but the MPH could be better. Underneath these cars are somewhat similar, so it makes for a great race!
That's very true... but it's also not allowed in the Pure Stock Muscle Car Drag Race series. haha
@@CarsAndZebras Exhaust cutouts were NHRA allowed back in the day. Two inch diameter Pipe with screw on end caps. Cut pipe in center on 90 degree angle, weld cut areas to exhaust pipes at first bend. Travel to Atco Dragway, crawl under GTO and unscrew caps with a pipe wrench. Automatic 20+ HP increase and 2 MPH increases Trap Speed. Performed this NHRA legal Stock Class Mod on a few cars I raced back in the day. Also Legal at the 1970 NHRA Indianapolis Spring Nationals for all Stock Classes. Just thought I would Throw this tidbit out there. The Video's are Impressive. Thank You.
When Pontiac came out with the 455 and the Mark IV Ram Air, I was online !

Yup, decided to "Up my game".....
Love to see that 71-72 Mustang coupe in the background of the GTO
Really cool to see Thanks keep up the good work
I have no Idea what you're talking about but the cars are great!
You’ve got the coolest channel dude. Heck yeah.
Another great video 👍👍👍
good Lord the rumble of that ble Dodge at the end! im still an Olds man at heart!!!
If the Buick hadn't red lit,the second race would've been much closer.These two cars are as close to a evenly matched as you're going to get,the first race was very close with the GTO having the higher mph as they went through the lights.
You're right. Very similar cars in power and weight. Both with great low end torque.
@@CarsAndZebras Buick 455 GSX would easily beat the GTO 455 XO.
Love 64' - 67' GTO's. 1971 not so much; Buick (the gentlemans muscle car) was better looking for 71'
I think I favor the looks of the Buick just a little more in '71 as well. I do have a recent video posted of a '65 GTO Royal Bobcat, so you might enjoy that!
Test drove a used 67 GTO with Automatic. I was 19 years old and they wanted about $1300 as I recall. I punched it in first gear and when it shifted, started rolling off two black patches for a long while, stayed perfectly straight. It was the most exciting car i had driven at the time.
Never liked the looks of the 70-72 GTO. Always thought the Buick's and Oldsmobile's were the best looking of the 1970-72 GM A-Bodies
My dad restored 2 67 gto’s for a guy back when I was around 9 years old. My mom took my sister and I for a ride and smoked the tires through 3rd gear! I fell in love with those cars from then on
Yes the Buick a beautiful car a lot like the 442 in looks
I'd have to take the Buick if I could choose one
Can we get a video on the white mustang in the background at 1:50?
Cuz I'm a father I appreciated this video. Because of the Buick, I loved this video, what a beautiful vehicle!
Both those cars are drool-worthy!
Both look awesome and drive very nicely! Quick and comfortable
Hardcore Ford Lover here, but that Buick is Beautiful. I always said the Only GM Car i would Love to own is the 70 Buick GS Stage 1 Those Big Buick Engines are Torque Monsters. I Believe the 70 was rated at 360 H.P. 510 Ft.Lbs. That Torque Number is Nuts, can definitely get that Buick Rolling. I Believe Buick made the Best 455 out there, Way Better than Olds and Pontiac. And i Really Love the Looks of the Buick compared to the Chevelle, 442, GTO. Probably my Favorite GM Muscle Car. I gotta admit i do like the 69-72 Nova Too. Would make a Killer Nova with a Built Big Block FORD !
And Pontiacs big number engine could push 390hp and forget tq numbers( the GTO hp rating was spun down vs full-size cars yet same engine!)
The Pontiac 455SD was the superior engine all around. Provision for Dry Sump oiling, web reinforcement internally of the block, superior rods, forged crank, best flowing heads this side of an RA V. Saddled with a wimpy cam and low compression, these were still very much a better engine.
Nice cars. Who knew that by lowering compression to mid 8:1 would lower ET’s...? Low 12’s, Haha - nyet. Breathed on, but still nice.
These cars are so loud that even when I put this video on mute I can still hear them roar.
👍
Remember "Little Joe"...Mark Busher's GS!
2 GM legends!!
Yeah, two of my favorites!
Just wondering you put round one one the screen.why can't you post the tines on the screen
Those GM A-Body muscle cars 1968-1972 were great cars. They were:
Buick Skylark GSX with Stage 1 Fireball 455 V-8
Chevrolet Chevelle SS with LS6 454 V-8 Cowl Induction
Oldsmobile Cutlass Hurst/Olds 442 with Rocket 455 V-8
Pontiac Tempest GTO with Super Duty 455 V-8 Ram Air
There is nothing like a pair of Beautiful American muscle cars just saying
Nice buick i got 2 68 rivieras i installed a 455 in both of them one is a gs love my buick
Alex, good move, the 430 is a great passenger car engine, but they are a bit fragile due to some lubrication issues...I had a 69 Electra convert back in the day, and that 430 was a tricky skid-ish engine. Just after rebuilding the whole engine with new aftermarket pistons and cam, somehow Oil was blocked from getting to the drivers side lifter bank! It took a special "Oil galley bypass" kit from a Buick aftermarket house, and removing the transmission and Flywheel to access the galley plugs in the rear of the motor. What a nerve wracking experience - but it worked out. After it was running great about 3000 miles into new motor the transmission caved in, and had to pull it again! I got really good at that job....lol....455's have allot better oiling systems and lower end, Love dem Buicks!
Awesome video.
These cars aren't stock.
The Buick's weight advantage can be attributed to it's 455.
It's a tick faster than the Pontiac in the 1/4 mile.
But the GTO, got the girls.
true..my Chevelle 325 HP 1970 ran 14.20@98.19 back then.
Open hedders and a Holley.
What about a 69 judge 400 ram air V can it beat Buick stage 2
@@AlejandroP1980s
They are so limited and rare, few ppl know.
...and there was no 69 RA V Judge.
@@AlejandroP1980s there is a story about that match up in 70. The story goes that the stage 2 car got the gto ra5 by two car lengths, but don't know if anyone there is still alive to verify it.
I had that 70 GTO with the 455 and Hurst 4 speed. Definitely a fun car, slippery!
Rusty...torque does the job - ya...! I luckily grabbed a 70 Tempest Gt37 7 years ago. Fresh 400 with RAIII cam 4 speed with Chev 3:31 axle....I just had new control arms put on rear, and front end tightened up, and Slippery...is a good word for it now! Not as fast as your car was, i'm built a bit lower in compression for unleaded pump 89 octane....I drive it ALLOT!
I like the 1970 GTO bumper better. Blended with the car much better. The 1971 bumper looked like it was somewhat disjointed.
So what mods ARE allowed? Both cars are easily a second quicker in the 1/4 mile than stock. I used to drag race in the 1970’s and have first hand experience as to what stock muscle cars ran back in the day.
Quoted for truth. So many stories get told by people who exaggerate what cars ran back in the day. This is an honest post. Kudos!
Blows me away that my S10 Blazer weighs the same (~3500 lbs.) as those muscle cars. Guess that HP was needed to get those heavy duty beasties moving?! My Pop raced a '67 Chevelle w/ a 327 and always seemed to win his class. Found out years later that he did port work, as well as undercut valves, on his (non-double hump) heads and that was the difference that gave him the edge.
The 327 was definitely a great motor. A little bit of porting work and the right gears and those things couldn’t really scream!
Sorry, accidently hit 'comment' when I didn't mean too. The video is 4 years on so it didn't make any sense to comment. Guess now that I'm here I just wanted to mention that both cars were much heavier then what you reported. The Buick was listed around 3,721 lbs. w/o driver. The Pontiac around 3,845 lbs. w/o driver. My comment was really triggered by the 1/4 mi. times you mentioned. Neither car could run mid 13's, otherwise the 0-60 times would be around 5 sec., not the low 6 sec. range. Anyway, that's my flubbed-up comment. Thanks for the video.
68 to 72 are the sporty A body;s , for 73 they got too big and too heavy.
There were no 12-second muscle cars back in the sixties and seventies unless you had headers, slicks and gears. So I wouldn't call these stock
Despite the series' name, cars racing at in the "PURE STOCK DRAGS" are pretty far from pure stock in terms of their original production state. The PURE STOCK DRAGS incorporate the NHRA's "stock" technical specs, which permit 3 angle valve jobs, over-bores of up to .060", super thin head gaskets and so on. The "PURE STOCK DRAGS" allow further mods in the form of "improved stock cams" (faster ramp angles for greater average lift), modern pistons, rings, rods, electronic ignitions, modern, mandrel bent 2.5" dual exhaust systems with low restriction mufflers, drag oriented suspension mods and so on.
Summarily, the old muscle cars you're seeing here are NOT "pure stock," but are instead purpose built cars.
This particular Pontiac is one of the more famous cars participating in the series. Check out it's engine specs relative to the stock state:
www.hemmings.com/blog/article/sleight-of-hand-sedan-1971-pontiac-le-mans-t-37-455/
Thanks for the link👍
No wear near stock should be the name.
Don't forget the mods in the fully rollerized automatics
NOT?
Street cars just generally weren’t too much quicker that a 14 second 1/4, back in the day. Lots of reasons, but something in the 13’s was quick. You knew both of these were breathed on. It’s ok, just don’t try to pass off like it’s Uncle Joe’s GTO.
Keep in mind that all auto makers then, especially GM, HIGHLY underrated their advertised horsepower to help avoid crushing insurance costs.
From your experience who is the go to guy to build and engine for this class or even the F.A.S.T class. Great videos
I'm not sure who the FAST guys use, but there's not one specific person in the Pure Stocks. Pure Stocks really only allow 1.5 points over stock compression ratio, and no other major modifications, so any high quality performance shop could handle that. Some of the Buick guys will send out to some Buick specialist to correct the 455 oiling issues, outside of that I haven't seen any specifics.
2 ... 1971 455 GM'S .....
ALTHOUGH BOTH HAVE LOWERED COMPRESSION RATIOS... THIS WELL WORTH A LOOK SEE !!!!!
big block 455 versus small block 455 , pfft we already knew the outcome
QUESTION....Why Was the GTO FASTER IN THE LEFT LANE AND THEN SLOWER In THE RIGHT..? I LIKE THE GS & GTO EVEN IF THE GS WAS A BIT SLOW..NEEDS MORE WORK..??
Daniel Gray , the Buick red lighted.
Please is these vedios new or old
Cool race, but the track needs to work on that stuck win light. ;-)
Classic GTO love ♥
Imagine what the numbers would be adding a simple Paxton Supercharger to the low compression engines.
In '71 they weren't that low yet on the performance motors, probably around 10-1.
mikesteelheart, Buick 455 compression dropped from ‘70 (10:1) to ‘71 (8.5-9:1). The SAE (gross) hp dropped 10hp, I think. When they went to SAE (net) in 1972, hp dropped again, with no change in compression, to more realistic power levels, realistic from the perspective of what the driver would feel behind the wheel.
@@mikesteelheart Not the Buick. I had one. It was a true 8.86 to 1 according to cranking compression. .
I wonder if Buicks get an added benefit from the rules when it comes to compression ratio.
Buick was known to say their engines had higher compression than they actually had. If true the Buick folks probably get to increase their compression 1.5 above advertised which nets around 1.8.
Just for nice to know Information. Back in the Day , you gained True info on True Speed enhancements from the Track, Speed Shops or Magazines. Friends not so much ! Baldwin Motion would advertise in magazines, ( East Coast reader for me ) a Hone-O-Drive Overdrive transmission Unit. Available for auto or Manual transmissions. A 4 :88 street gear with a 30 percent overdrive gave you about a 3:42 highway gear when utilized. HD units like the Hone-O-Drive were not a Common Knowledge item by most back then. I've witnessed Same Day, Pure off the showroom floor Big Block Muscle Cars with 4:33, 4:56 gears perform mid-low 13 second runs with the factory tune . Add only the Overdrive to your Muscle Car, you where a street light Bandit and a Highway cruiser all with a factory HD Ring a Pinion .
I miss you reading out the winner and loser.... sometimes it is hard to tell
Gear ratios seem strange on both cars. Pontiac used 3.55 and 3.90. Buick used 3.42 and 3.90. Chevrolet used both 3.31 and 3.73. B-P-O used a very different housing compared to Chevrolet and other than brake shoes and fluid, very little interchanged.
thegreenerthemeaner All 455 equipped GTOs, (‘70-‘72), came with a heavy-duty 12-bolt rear, so that’s why the gear ratios are a little different than the 10-bolt BOP rear that the 400 cid GTOs received.
Had a 1969 442 Olds I could kick myself a thousand times for ..
are these cars true stock ?? ...... pretty fast if stock off the showroom floor .. I thought they were high 13sec/low 14sec cars "stock" ...
Pure Stock Muscle Car Drag race. They allow some mods (compression ratio up 1.5 points, electronic ignition), so these cars really wake up with the compression ratio increase.
@@CarsAndZebras , got it thanks 👍🍻
You are correct it’s not original spec from the factory
@@CarsAndZebras What about porting, headers, cam?
As a former 70 GS 455 owner I did the same thing with the one I had.
The only thing that would give me a run was a 68 Mustang with a 429 in it.
And yes back in the 70’s I put away a lot of Hemi’s. They were truly what they were called and that was a Hemi killer.
im calling it now. buick gs. no contest.
dammit i was so sure.
A Boss 351 Mustang would be a great car for this type of comparison
Maybe, but there really aren’t any Mustangs that come to the Pure Stocks for some reason, so I just don’t get any footage of them unfortunately.
Dream cars what state is this in so many amazing cars
Everyone knows the Buick block used a thin wall casting it's the lightest of the GM 455 it weighs just a little more then a small block chevy ,could you show the rules for this class it is certainly not pure stock ?
In the late 80s my friend had a 70 GTO judge 455 we beat about everything back then except for a 76 Nova small block gave that goat a run for it's money.
Could be, but no factory 1970 Judge came with a 455 and all 1976 Novas were dogs. Hot-rodded and modified, things would change a lot, depending on many factors. From the factory, all 1970 Pontiac 455's were nothing more than the Bonneville engine anyway.
@@LR-my2di well I'm a pmd fan and yes the whole car was a clone not a true judge. Nothing factory when street racing back in the day. Didn't know cars would fetch what they get now.
@@martinp3371 So true. Some of the stuff we did back then was today's "OMG" stuff. Like ... "What was I thinking?" But we were having a good time living for the day, not for the future.
I am still waiting to hear you telling me what the cars ran I could not hear the speaker from the drag strip.
I'll bet more people would like to hear you tell us.
It’s shown in the video. Sounds like you might need new glasses. 😆
I had a '72 GTO. I put the 428 H.O. out of my grandma's old '69 Bonneville in it. The 428 had only 66k miles. I had a valve job done while the engine was out and I put headers on it. Other than that totally stock right down to the 068 cam and Quadrajet carb. My GTO had a turbo 400 and 3.55 rear gear. I ran the best of a 13.35 at 104. It was a beast for an almost totally stock engine. Too bad they never put the 428 in the GTO from the factory. Only a few Royal Bobcat GTO's had them.
That’s nuts! I completely forgot about the 428 in the bonneville
@@CarsAndZebras Yeah, and it could be had in a Grand Prix too. Rated at 360hp standard or 390hp in H.O. form. But neither car would be great for drag racing. Thanks for the great videos.
I took a 69 Bonneville 428 and rebuilt it with a mild cam and headers. put it in a 70 firebird with a stock 400 turbo. with street tires it would roast both rear tires from a 30 mph punch.
I junked cars AND bought and sold cars...seriously..I had a 66 Bonny convt w 421 fact 4 spd.
Had a junky 66 GTO w 421 4 spd...junked it but it was scary fast...front end...baaaaaddd...
Had 65 GTO.. 400 3 spd...It was pretty quick...Last GTO was 68 400 4 spd,Clutch went out surprise ......Traded it 68 Impala...307 P glide...winter time no garage needed a car...had quit dealing cars..
428 was beast, then went to 455. Bad ass engine. 360 or 390 hp. I HAVE 1969 Catalina Ventura that's supposed to be a factory 428 car but alas it was bought and denoed till it cracked block/heads. Car now needs full resto. Basically same body but 6 in shorter than Executive, Bonneville,Starchief in 69.
The Buick may not be a Stage 1 car, it is lacking both the chrome valve covers and Stage 1 emblems on fenders. They may have added Stage 1 heads and cam ? Bad ass car in any case...
8.4 - 1 comp = perfect for a turbo charger !
C&Z I can’t see the ET and speed, at the end, who won these races!
Who won? Cant see the board?
Kenny Davis gto won both I’m pretty sure Buick jumped the gun on the second race
@@Recon1500 look closer
Not a stage 1 car, its a GS 455 built to stage 1 specs? Also, why does GS have radial tires, radial tires are not allowed for pure stock drags unless they were original equipment?
12s yeah both are making more power probably around 400 or a bit more
From what I know. These cars are only allowed to use electronic ignition instead of points and bump up compression a little bit maybe a point or so. No porting heads, no aftermarket camshafts, no headers etc. So basically the same things you could have done to your car at the dealership before you drove it home.
So with right about 1320 the GTO was starting to get its go on while the GS had it up front where it mattered but was flat out when the GTO passed it. The rear gear making a difference big time.
What were the times, who won which race? Buck
Hard to see the times. Please either mention the times or insert text into the video
