PONTIAC - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO
WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY 405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS who taught me most of what I know, often told me Chevy rated their horsepower in a more optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac rated/tested their engines in a 100 degree room, compared to Chevy in a 60 degree room. These Dyno results seem to reflect that some of what I heard was true. Both of these engines are great, but the results do seem to show that Pontiac was not rating their horsepower worrying if it would cause "songs to be written" about their engines .... like the great song "She's real fine my 409"--(Chevy).
1962 Pontiac Catalina 421 Super Duty - Gateway Motorsports Park - Huge Wheelie
Be sure to check us out on Facebook at:
This is a video of an awesome 9 Second, 1962 Pontiac Catalina. This Super
Stock Pontiac was racing in the Nostalgia Drags at Gateway Motorsports
Park, just outside of St. Louis, MO. It's an original 421 Super Duty car
and man do they have it set up right. This thing hooks hard and leaves
straight every time. Definitely nothing wrong with a mid 9 second quarter
mile at 143 mph. I thought you might get a kick out of that huge wheelie he
pulled on the one run. I hope you found it interesting....thanks for

PONTIAC - "The Super Duty Story" Part 1 of 3
Pontiac had an SD engine program in the late 50s early 60s, and
later/briefly again in 1973/74 with the SD455. This video is regarding the
FIRST Super Duty program.---In only a few years time during the late 50s
early 60s, Pontiac MORE THAN DOUBLED their V8's horsepower output (described
in this video), while using/keeping the same V8 engine block they used thru
1955-81. Even though the same block was kept, from 1955-62 the cubic inch
displacement grew much larger than the initial 287 cuber it started as in
1955. It grew to a 317 347 370 389 and finally a 421 cuber in 1962. It
eventually maxed out at 455 cubes in 1970. By 1970 ALL the other GM
divisions were producing engines at 454 or 455 cubes (500 for Cadillac).
PONTIAC WAS THE ONLY DIVISION still using the same block they used in the
1950s on engines that had a much smaller displacement -- 287 cubes. The
1955 287 displacement would remain the smallest displacement ever used in
the Pontiac V8 block all the way until 1980/81 when a 265V8 was produced.
Since less durability was required for the smaller displacement, the block
was decked/butchered/lightened on the 265/301v8s of 1980/81. Prior to 1980
the block had never been decked/butchered/lightened. The 1980/81 265/301v8
blocks were about 200 pounds lighter than the 1955-79 blocks, and only 25
pounds heavier than a Buick 231V6.
409 Chevy Engine Build -- Part 1
This Chevrolet 409 build is meant to be a wolf in sheep's clothing. We
stroked the rotating assembly to up the displacement from 409 to 440 cubic
inches and then replaced the stock heads with much more capable units from
Edelbrock--but painted them to disguise the modern aluminum castings. The
end result is 505 horsepower and 507 ft/lbs of

Wide-Track: 1959 Bonneville - /BIG MUSCLE
• Chuck Cushner
Slathered in Lamborghini orange paint and exuding a presence that is
anything but subtle, this 1959 Bonneville is a car that represents a peak
time in American automotive design. It was drafted before government
mandates and regulations stifled imagination and creativity, and takes us
back to an era when we still looked to the stars for inspiration. This is a
car that will stop you dead in your tracks and make you truly long for the
days when chrome was King, gas was a mere .25¢ per gallon, and where Elvis
Presley was the greatest thing the public had ever heard.
