Lot S152 1962 Pontiac Super Duty 421 405 HP 4 Speed

[cathleen127]

My brother has the 1963 October issue of Motor Trend magazine which tested this 421 405 HP engine out at over 500 HP. This was one of the hairiest engines ever made bar none.

interesting car and driver magazine issue 65 catalina 2-2 o-60 in 3.2 seconds never been approched by any one else for production gm or chrysler or ford or?

Actually they made both cast iron and aluminum headers, one set for NASCAR and one for SS Drags. No tunnel rams from the factory but the manifold runner design was recast in the new manifold for later engines beginning with the 400. The solid lifter cam was a McKeller #10 later made as a hydraulic version in the Ram Air IV engines. Super Duty began it's life in 1957 with over the counter parts that NHRA required to come on the vehicle in 1962. '56 dual qual Isky E2 engine not called Super Duty

That Engine Compartment is a Thing of Beauty! No Power Accessories anywhere. It took a Man to Stop it! And the 405hp Rating Was Way Conservative, for the Insurance Underwriters, More Like 500hp! The 421 Fully Decked weighed Less Than Its Little Brother, the 389. I Feel Lucky to have Lived Thru that Era, It will Never Happen Again!

@bobyoung53

You're both right and wrong. Some 5 where actually built in late '62, none of which now exist, but the other 8 Swiss-Chesse cars were finished up for the summer of 1963 season.

[MiracleMile90]

If only these cars had much higher gearing.............they would be almost unstoppable.

[samjezard]

i wonder what one of these would run with a good set of slicks...

[4431prw]

stock, with the aluminum body's and Swiss cheese frame, they ran a impressive 11.50 in the 1/4 mile.

[Skeletoil]

did you the pic where 40 or 50 hemi darts with fiberglass front ends and acid dipped bumpers with hemis were getting ready to be shipped? We spanked your when you were born!

[quickdeuce]

XCLNT video - They were FAST as hell and are very rare. I you find one - grab it and sit tight.$Value$ will keep going through the roof.

[Maxwell2323]

anyone know of a source for some refirb'd air cleaners like these for a dual quad? Can't find them anywhere.

[Maxwell2323]

Single master cylinder = balls.

I have 2, so I went with a dual master... :)

[tamapalagi]

Look at the puny single master cylinder. All go no whoa.

[Maxwell2323]

Did this one sell?

[rahoho98]

It is still for sale

[peter355camaro]

low 11's from the factory..are you kidding mee?? maan that car was the fastest production car on the planet that year!! respect those super duty pontiacs..

[Dummerd]

421 with two four barrels, solid lifter camshaft and 12 to 1 compression. P O W E R.

Pontiac wasn't messing around in those days. Heater delete, factory headsers, tunnel rams, aluminum body parts and bumpers, over 400 hp and 3500 lbs.

Yes, all go and very little whoa.

[dajudge1969]

That is nasty, wish factory cars were still putting out those kind of vehicles

[peak199]

@Dummerd also,these engines were drastically underated as far as''405'' horse.more like 460 to 480.

[Sarcasticscum]

@Dummerd

Yea, but the cons of this car where:

1) If used for a prolonged amount of time, the aluminum "long-branch" header were famous for melting down under extreme heat.

2) Hardly any original "Swiss-Cheese" frames exist due to the fact that when they drilled holes through the frame, they not only lightened that car, but they also made several hundred fracture points in the frame!!!

[tjfreak]

Thats extremely fast.. you hear quarter mile #'s tossed around all the time that are so exaggerated and embellished, so few factory cars ever achieved this number..1/2 of the modified cars out there don't even do this.
