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).
65 Chevy Impala SS open headers irritates my neighbor
Here's my original high school car, numbers matching (327 c.u.i.) bought in
1972. Decided to open the headers and cruise around my subdivision a
little, but end up ticking off my neighbor. I didn't even drive by his
house - he lives up the block the opposite direction. When he heads to the
back of my car to take a pic of my license plate, I realize this could turn
against me. Funny thing is, he doesn't actually recognize me until I get
out of the car - then we "share the love".

PONTIAC - "The Super Duty Story" Part 3 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.
