One of best friends bout new a 1970 firebird formula 400 ..dark blue with auto trans. Sweet car..he wanted to sell it to me for a about $1500 and of course I didn't...back then there were many muscle cars for sale..........

Don Mann me too, believe a SD 421 Catalina ,hooked me in 1962 at the Gas Station my High School Buddies hung about....

Nothing like a 421 Super Duty 🏁

She was a beast ! 🏁

And enjoy your high 12s low 13s from the factory 🏁

The 421 h.o. I put in my 65 G.T.O. was modified.. had about 550 h.p.

Yes it was , no other Poncho in the 1960s could touch her , Goats , Firebirds all bow to the Mighty 421 🏁🏁🏁

The 421 SD actually first came out late in 1961 as a crate engine. But in 62 they started factory installing them because of an NHRA rule change

Brian Cabral Thanks Brian!

@@MuscleCarOfTheWeek I agree ! And if you were from ISRAEL I'd say "Jew da man" HAHAHA

"Ned im on fire put me out." Fireball Roberts last words to his friend Ned Jarrett. According to Ned.

I'm a Mopar guy and a big fan of Richard Petty but Fireball would've gone down as maybe the greatest of all time if he didn't get die from the burns he suffered in that crash at Charlotte. Fireball was one hell of a race car driver

My dad had one,that he raced. He came from money , but he made sure that he spent every dime on racing .

'63 They only made 14 SD's, then GM shut down Pontiac's Racing program !

Watch Jay Leno

Me too. But add a 69 Ram Air IV GTO to the list too...and a 57 Bonneville 347 Tri Power

You can still build one...

Yup I've seen it myself. The factory 405 hp rating is laughable. Saw a bone stock 421 SD on an engine dyno and it peaked at 488 horsepower at 6000 rpm and well over 500 lb/ft of torque. A lot of people don't know how awesome the SD Catalina's really were because they go by the factory horsepower rating and think that's all the power those engines made

Percentage-wise how much would aluminum make the car lighter?

Division of GM same as Chevrolet was a division.

Chevrolet/GMC, Pontiac, Oldsmobile, Buick, and Cadillac were all divisions of GM

I saw a bone stock 421 SD on an engine dyno and it peaked at 488 horsepower at 6000 rpm and well over 500 lb/ft of torque. Seriously underrated engine

That sounds about right the 421 Super Duty were severly underated ( 405 factory rated hp ) actually putting out between 460-480 hp stock from the factory 🏁

Most definitely, they honestly put down at the flywheel over 490hp and 497-500+lb ft of Tq with OE casted D port heads. Kind of insane honestly. Butler tested one on thier Dyno and came up with those #,s. My 1969 Pontiac 400 four bolt main put down 480hp and 532 ft of Tq at the flywheel when it was Dynoed in 2017 by my local builder of all types of race engines with 50yrs of experience now. It’s original Nodular Iron crank was lightening, knife edged, journal’s were highly polished. Coated racing bearings were installed, 1974 SD rods were sourced, shot peened and resized 3 times. ARP series 2000 fasteners were used on the mains and rods. Billet Ross coated flat top dual relief pistons are used with titanium full floating wrist pins. It’s completed rotation assembly was balanced to within 1/4 gram across the whole assembly included my harmonic balancer and flex plate. It’s Zero decked with Butler prepared 1969 #62 heads that were bowl ported and runner cleaned and gasket matched to my current Edelbrock Torquer intake. Carb is a 1976 Quadrajet 800CFM unit that was opened up/reworked by my builder to 850+ Cfm max he told me. Fuel pump currently is a Carter 140Gph mechanical. I have 340/355 Cfm CNC ported KRE aluminum heads with portmatched gasket matched Northwind intake waiting to be installed with a Robb Mc surge tank and Quick fuel BDQ 950 with 1050 Cfm center section to be installed once it’s running and dialed in. I was told by many builders who really know what they are doing like Jeff Kauffman, a rep at Butler, two guys at SD performance, All Pontiac.com and also Lynn Mcarty and his current Pontiac N/A record breaking/holding Crankshaft builder Dave in Michigan, they have all told me I don’t need a stroker kit or more bore in my 400/406 to get past 600hp and Lb ft of Tq at the flywheel with it on pump gas. My KRE heads are 74cc chambers, Jeff told me 89-91octane will run well. So yes I’m very excited but want to make sure all my upgraded fuel delivery components are all set up before I go forward with the install. My current 1969 #62 heads flow Maby 260-280 Cfm if I’m lucky. She runs nice so far however if you do the math.340-350Max Cfm CNC ported Aluminum heads should get me close to 600Lb ft of Tq & 600hp, probably a lil more if my calculations are correct. They usually are 😉. I was told they can support up to 1200Cfm of fuel delivery however I’m not anxious to bend one of my Super Duty connecting rods to find out. Road Course racing is my major concern with it and perhaps an occasional 1/4 mile or 1/2 mile run. Also of course cruising with my kids during local car events as well. It’s in my1964, 3212Lb Tempest Custom 2dr post car backed by a built for racing 200-4r with two Trans oil coolers. The Trans is built to withstand up to 900Lb ft of Tq. I’ve had the car since 1995 and now finally, most recently, I’ve got it fully adjustable QA1 equipped and a quality Willwood 4 disk I installed as well. It was a lot of work to get it all right and tight but severely worth it.

@@joshbrekke6374 The Pontiac Super Duty 421 was one badass factory race engine that bows to no make or muscle cars of the 1960s , no one ! 🏁

@@davegeisler7802 exactly, and it paved the way for future copy cats. Starting with the SD 389 around 1959-60. Remember the 1963 SD 421 Lemans that Won the Special race in Florida? By over 4 laps?!!!! It was bought by Mercedes and never seen again. AMG my ass! I vow to prove my 406 will never bow to any N/A LS and I plan to prove it too.

First thing I think of when I see a 61 or 62 Pontiac is Fireball Roberts

Chris - the bare bones, baseline version of many cars of that era didn’t include exterior mirrors.

Needs headers and head work...another 50 h.p.

My dad raced a 62 SD 421 with the aluminum front clip. Believe me,those Ol dogs knew that . 150 made and he sold his ,that he bought new in 1999 for 8000$ . Had cancer , and I'm a Ford 427sohc man.

It is great to see Pontiac getting it's much owed credit they were and will always live in history as the pretty performers that they are RIP PMD.

Also RIP Mr Nat Khan of Khan motors a Pontiac dealer that my dad worked for in englwood NJ.

The 455 SD was discontinued in 74. No SD's were built after that. Impossible to have a 76 455 SD unless one was put in it after the fact.

@@jamesspalten1772 The reason I called mine an SD is because we put the 4 Bolt main Caps on that block. My Dad also owned a machine shop called Colby Automotive. It came with the 455 & a Super T -10 4 Speed. Since my Dad built Pontiac's, we always had a set of 4 Bolt Main caps laying around. That's why I called mine a SD 455.

No such thing as a 76 SD-455. They only made them in 73-74. The SD-455 block was totally different than a regular 455. The SD had 4 bolt mains, extra webbing around the lifter bores and in the camshaft area, provisions for dry sump oiling, and a bigger distributor. The SD heads also had round ports and the regular 455 had D shaped ports. They had some other differences too but I can't remember them all. Really impressive engines. Performance and durability wise they far exceeded anything else built in 1973-74

@@jeremythompson9122 Lol, you do know they sell 4 Bolt main caps for Pontiac blocks right?? My Trans Am was a 76, the motor was not. So before you get on your little pontiac high horse, remember people do ENGINE/PARTS SWAPS to make said 455 Super Duty. #asshat

The engines with aluminum exhaust manifolds carried a warning not to exceed 70 MPH for more than 15 seconds. So, yes - you are correct! Fortunately, a dragstrip run was over way before 15 seconds...

@@paulplack490 - This is also why Top Fuel and funny cars have no cooling systems. They aren't run long enough to be needed.

I knew a guy that raced a '62 Catalina with the 421 since he bought it in 1964 , he thought the sedan would be faster also , so he found one and swapped in his drivetrain. The sedan ran slower than the hardtop , so he swapped everything back .

The eight lug wheels were optional equipment. The aluminum center hub / brake drum replaced the stock drums and bolted on with the stock five studs, the outer rim bolted to the hub / drum with eight lugs .

@@bobbrinkerhoff3592 Thanks for the info. 👍

I PUT A 421 H.O. AND MODIFIED IN MY 1965 G.T.O. after I blew the 389 motor...turned mid 12 seconds... I beat all the competition..and the 2 motors looked the same....

Such a shame what GM has become. Just a globalist puppet corporation. I'll never buy another GM product again as long as I live. They take billions in bailouts from us then once they had our money they close multiple plants in North America and move to Mexico anyways. Typical scumbag Liberal move. They can go totally bankrupt for all I care. I'll stick to buying either Ford or Dodge products now
