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 Banshee A Longer Look
The Banshee was a vision for what the Firebird could become. Of course,
this concept car could never be built exactly, too low on the road and it
wouldn't pass the safety and crash tests, but it was exciting. It
demonstrated that the problem with GM cars didn't sit on the designers'
shoulders. They were more than capable of dreaming up engaging and fun
vehicles that would set imaginations on fire.

77 Plantinum Bandit @ The Dyno!
Here is a quick upload of the Dyno session we did with the
Platinum Bandit just after the TA Nats this year.
The Platinum Bandit, is an original 77 SE 4spd TA, that we converted over
to a lot of modern technology to make it a fun road ready car with a lot of
power. The 474 stroked engine we recently built for it with the help of
Butler Performance, will be featured in the next issue of High Performance
Pontiac Magazine. Pushing 585HP off of 89 Ethanol fuel, with plenty of
vacuum and drive-ability, really makes this car come alive! I will be
posting a video of all the updated components and their manufacturers soon.
