I read in a magazine that back in the day they used an accelerometer inside the car and ran the numbers it these cars were closer to 450 hp from the factory.
The rarest of the 421 Super Duty Pontiac's is the 63 Grand Prix 421 SD. Only 3 ever built. But any 421 SD Pontiac is really scarce. Im a Mopar guy first but also a big fan of Pontiac. Especially the full size Bonneville's, Catalina's, and Grand Prix's that also happened to be fast. Mopar and Pontiac always seemed to be more performance oriented than any other manufacturers. The 421 Super Duty cars are the meanest ever produced by Pontiac.The street version of the 421 was no slouch either...the 421 HO. Even the 57 Bonneville and the 58 Bonneville with the 370 and Tri Power or the really rare factory fuel injection setup were some of the fastest cars on the street in their day as well as the early 60's Grand Prix, Bonneville, and Catalina with the High Performance 389 and a 4 speed . My favorite Pontiac's ever made are the 62 Catalina bubble top 421 SD, the 65 Catalina 2+2 with the Tri Power 421 HO and a 4 speed, and the 69 Grand Prix SJ with the 428 HO and a 4 speed. All 64-67 2+2's and 69-72 GP SJ/SSJ's were really nice cars. Would love a 69 GTO or Firebird Ram Air IV or a 70 1/2 RA IV or 73 455 SD Trans Am though. Really any 64-73 GTO or 67-74 Firebird or T/A would do. Pontiac built some of the fastest and coolest cars on the street and on the race tracks from the late 50's up into the early to mid 70's...and even a couple in the late 70's...the 77-79 Trans Am 400-4 speed(not the Olds 403/auto) and the 77 Can Am also with the Pontiac 400. Any T/A or Can Am sold in California automatically got the Olds 403 because the Pontiac 400 couldn't meet California emissions standards anymore and the 455 was discontinued after 1976
The olds 402 was a HORRIBLE Engine. I still like the 389 tri-power, factory they are dogs simply because the other 2 carbs were vaccum, but you CAN link them up mechanically and wow what a difference.
This by far to me is one of the coolest videos on youtube I like how corvair got him to crank her up I live in a very old house, love turning up the sound, having the windows rattle Love it Great work corvair
Awesome. Prolly worth $150k by now. Takes me back to my youth. I sold my 62, 348 HP Grand Prix in 1965 the day before I got drafted. Bought another on this week 56 years later.
I saw one of those (1962) at a car show 10-15 years ago and they started it up, it was deafening, but a good deafening! 🤣If I could have any muscle car it would be one of those.
Just stumbled accross this. THANK you and the owner of the car for lighting it up. Wowwwwwwwwwwwwwww.... (Need more W's!). What a sound!! Mmmm.... Love It!!
such a good show. i cant believe how many cars were there, and how PERFECT of a day it was. will have to make the trip up from CT again next year. i only did the drag racing, but that car sounded EPIC coming down the return road to get his trophy. best of show indeed!
Pretty sure it is worth way more, original super duty catalinas from 62 and 63 are worth as much if not more in most cases than judges. Can easily get 6 figures out of this car... literally the holy grail of Pontiac Motors
I was just looking at a 63 Bonneville 389, non factory 4 speed on Columbus Ohio Craigslist. I'm a GM guy through and through, but except for the 68 69 70 mopars, I don't like that body, I love them all. Even Fords, just don't tell anybody I'd drive a Ford...
I have a Video of these cars racing Max Wedge, Hemi, ford 429's, chevy 409's. SD 421's. In the end it came down to 2 Max wedge's and one 421 SD. The 421 ran High 10's but was beat by a Max wedge that ran 10's also.
The downside to these cars was that the "Swiss Cheese" frames often developed earlier-than-intended stress cracks causing frames to shatter at the rear. Another problem was the aluminum headers which would melt after continued use. Overall, they made impressive runs but had horrible durability.
@JusticeYouWant2010 You man, know your facts! I can't afford any Pontiacs on my wish list currently. They are, in no specific order... 1965 GTO, 1965 Bonneville or Catalina. All of couse with a Tri Power and 4 speed. Convertible or hardtop. I saw two beee-uteeful 65's at the next Musclepalooza, both owned by same fellow. I vidded him leaving the event. One lite yellow, one Iris Mist, (Evening Orchid, Chevy color too!) I've got a late 50's Corvette on the list too, and a 409, and ....
Mopar built a 426 Max Wedge in 63 with 13.5:1 compression. They also had an 11.0:1 version that was a bit more streetable. I believe the Pontiac 421 SD had 12.5:1 compression
A stock 62 421 SD Catalina would annihilate a stock 62 409 Chevy Bel Air. The 421SD made about 80 more horsepower than a Chevy 409/409 did. I've witnessed it on an engine dyno
No 409 could touch this thing. The 421, 426, and 427 are why Chevy dropped the 409 and designed the 396. The 421 SD made 488 hp on Butler's dyno in factory trim. Chevy wouldn't equal this motor until the debut of the L88. (In '67)
Nah I have to say once the racing Hemi came out and the GM restrictions came out that limited GM performance overall. Remember with Mopar you could buy a factory dragster if you had the cash but if you wanted one from Ford or even the racing engine you where put on a list and chosen from that list and had to be a sponsored Ford racer. GM as far as competitiveness after the 64 ban didnt really come into its own until the 70's
Would love to actually see footage of the WHOLE CAR, and not just several minutes of closeups of paperwork, plaques, individual engine components etc. Seeing the actual car from more than 6 - 36 inches away would be nice...
If I was going to put a car in a show room I might use the Skinny Bias ply UNSAFE rubber that we had at that time but If I wasn't an anal retentive Purest I would enjoy the car with better driving modern tire's of today . That's why I dislike the Purest like I do... they should have there own car show away from the guy's who actually built there car's to drive and enjoy what a waste of machinery

Who needs a radio when you have a Pontiac engine singing beutifull music?
Nothing like the sound of a 421 SD with the exhaust cutouts open. What a monster

421catalina is no joke. Set speed records.

Speed channel recently did an episode where they rebuilt a 62/63 SD 421 engine to stock specs. After rebuild it Dyno'd at 480 Horse Power.
Pontiac is in my blood. Watching this video just made my day!
Barclay Benjamin I have a '65 Grand Prix, nice loaded survivor car
such a good show. i cant believe how many cars were there, and how PERFECT of a day it was. will have to make the trip up from CT again next year. i only did the drag racing, but that car sounded EPIC coming down the return road to get his trophy. best of show indeed!
Drag way 42? Yes I have been there! That is the infamous dragway 42 in Ohio! Great old Pontiac!
Yup, those were the days!
To me, this Pontiac would be far more valuable than any Hemi. And it will be one day...
ghm389 Right on, brother! It is worth far more to me today!
Pretty sure it is worth way more, original super duty catalinas from 62 and 63 are worth as much if not more in most cases than judges. Can easily get 6 figures out of this car... literally the holy grail of Pontiac Motors
@PontiacAlfaHSV What about the 409's that Grumpy Jenkins ran? and later the Hemi twin cam Olds 455???
Sounds amazing I'm mopar guy but these Pontiac engines were fuckn beasts
I was just looking at a 63 Bonneville 389, non factory 4 speed on Columbus Ohio Craigslist. I'm a GM guy through and through, but except for the 68 69 70 mopars, I don't like that body, I love them all. Even Fords, just don't tell anybody I'd drive a Ford...
I was too young, but I enjoy reading Joe Oldham in HMN Muscle Machines
@V8Deuce What's an extra 100 HP between friends???
WOW! simply amazing.
Saw 'em, too much ta look at!!! didn't know where ta turn... Back in Sept...
Incredible Poncho!!!
@The1FastGP Did u evr read the ad from Pontiac in 1962? Look it up, it just shows an empty garage, and text of the beautiful music!
Yup, those were the days!!! I'll be back at Musclepalooza in the fall... C u there???
Gentlemen, this was THE era for hot cars. Bar none. Period.
luv that intake manifold!
And quite the story how he found it!
@PontiacAlfaHSV WOW!!! Race on Sunday, sell on Monday!!!
@peak199 You're absolutely right. They did it with the GTO's and Firebirds as well.
Would you please tell me where you found that factory NOS interior? I am building a 64 Catalina and I need the NOS stuff. Thank you!
Wynn Wellman I was just the guy holding the camera, sorry I can't help
SMS Almost 20 Years Ago!
i had one...but i sold it...one of my first cars
it was a later year than this but not by mutch
I have a Video of these cars racing Max Wedge, Hemi, ford 429's, chevy 409's. SD 421's.
In the end it came down to 2 Max wedge's and one 421 SD.
The 421 ran High 10's but was beat by a Max wedge that ran 10's also.
SWEET car....you been to Norwalk for the event formerly known as " Tri-Power Sunday" ? Love those old Pontiacs !
I'm with you bro... I'm on your side! See you at Musclepalooza???
Norwalk? Ohio??? Where and when? But I have so many toy/events to go to!!! Sheesh!!!
The downside to these cars was that the "Swiss Cheese" frames often developed earlier-than-intended stress cracks causing frames to shatter at the rear. Another problem was the aluminum headers which would melt after continued use. Overall, they made impressive runs but had horrible durability.
Sweet !!!!
@CORVAIRWILD you got to many videos to find it bra
nice vid on the 421
Have a great summer
Happy Hottroddin
i would love to have that car
@g20s10silveradoman Somewhere in my Musclepalooza vids I have the best of show '63 Catalina liteweight. Black, Tri power, alum fenders...
Yup, rev er ta 5500 pop the CLUTCH!!!

RIP headphone users
Crank 'er UP!!!!!
Yup, talking about 10.5 to 11.5:1 compression on the stock max wedges and Hemi's
Mopar built a 426 Max Wedge in 63 with 13.5:1 compression. They also had an 11.0:1 version that was a bit more streetable. I believe the Pontiac 421 SD had 12.5:1 compression
@g20s10silveradoman Ooops, this is that vid!!! Sheesh!!!
I think it'd walk a 409.
A stock 62 421 SD Catalina would annihilate a stock 62 409 Chevy Bel Air. The 421SD made about 80 more horsepower than a Chevy 409/409 did. I've witnessed it on an engine dyno
I would think that this car is worth all of $400,000
Yeah, I know... But still awesome...
@3dsman It would be a good race for the 409's... ur welcome!!!
It would probably smoke a 409 unless it was the Z11
No 409 could touch this thing.
The 421, 426, and 427 are why Chevy dropped the 409 and designed the 396.
The 421 SD made 488 hp on Butler's dyno in factory trim. Chevy wouldn't equal this motor until the debut of the L88. (In '67)
Yup
Shame the microphone couldn't handle the SD.
@MrAshlandVideos Or maybe it's "shitty house'???

To bad they where running the wrong body, those Mopars where hard to beat.
@yadicals I woulda loved to be there!
Yeah, from $250 to $230k...
I had ta leave as he was preparing for awards... Shame...
Interesting! And fuel was CHEAP!
Very period, I suppose...
Nothing compares to this Pontiac muscle. Sorry
Could be... Or it wasn't raced much...
genu-whine!!!!!!
@4431prw Can you say "underrated"??? Lol...
Would love to actually see footage of the WHOLE CAR, and not just several minutes of closeups of paperwork, plaques, individual engine components etc. Seeing the actual car from more than 6 - 36 inches away would be nice...
@MrAshlandVideos Check out my vid "junk house"
Nasty!!!!!
I would drive the piss out of it . .......
To bad its a trailer queen.
@The1FastGP A-MEN!
"Special Frame" This is a Swiss cheese unit here folks.
If I was going to put a car in a show room I might use the Skinny Bias ply UNSAFE rubber that we had at that time but If I wasn't an anal retentive Purest I would enjoy the car with better driving modern tire's of today . That's why I dislike the Purest like I do... they should have there own car show away from the guy's who actually built there car's to drive and enjoy what a waste of machinery
