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
Gateway Motorsports Park

PONTIAC GTO Judge (1971 455cid, the differences basic supertuning can make)
Those who know me well, know that I always beat "SUPERTUNING"
"SUPERTUNING" "SUPERTUNING" into the ground. This video shows the
difference minor tuning can do (This is minor because a 1971 GTO's fuel/ign
calibrations are already geared for performance, so there's not as much
improvement you can make like you'd be able to on say - a late 70s
smogger). But on larger scales, HUGE differences can be made, as much
difference as adding performance parts alone. The more the car is severely
out of tune/adjust------which happens more with the more mods you make,
then the more you'll gain by supertuning it. There's another vid on YT
where an Olds 455 was built with performance parts to be totally streetable
but achieve 1hp per cubic inch. After they got the recipe of perfect parts
all together they were disappointed when she only Dynoed at 320hp. But luckily
they did not give up! After the proper ign-curve/timing & carb adjusts were
made, the engine jumped from 320 up to 455hp!! No doubt all the new
cam/intake/head mods put the old fuel/spark adjustments badly out of
calibration for the NEW BREATHING ABILITY. Also with things like dual quads
(especially to engines not originally equipped wit them), your adjustments
are most likely going to be way off and need calibration even more. There's
lots of dual quad cars out there not running well for this reason, however
the few that have been calibrated perfectly (EVERY adjustment set for the
best "stop watch" time, etc) truly do run like a bat out of hell!
