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.
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).
PONTIAC - The Glory Years! Part 1 of 5
(1956-93). Some great basic Pontiac history, along with the CARS and PEOPLE (Bunkie Knudsen, John Delorean, Jim Wangers, Pete Estes, etc) who made Pontiac great in those years. In 1956 Bunkie Knudsen was hired as Pontiac's General Manager. He was told by GM "Turn Pontiac around in 5 years or the division is gone". Within about a year he quickly assembled a great team. Knudsen was fortunate enough to pick up engineer John Delorean from Packard when that company closed, Delorean later became the father of the GTO and MANY Pontiac Innovations. Knudsen was also fortunate enough to lure a brilliant "Olds Rocket V8" engineer away from Oldsmobile---Pete Estes who helped the Pontiac V8 breath as well as it could.
