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).

This is a 468 cid Pontiac engine we build to Mike Matuszek and his '66 GTO.
The engine is based off a 455 cid pontiac block. An Eagle crank and rod
combo was used on the bottom end along with a set of KB forged pistons. A
Tin Indian Performance custom ground Comp Cams hyd roller was also used
with Comp Cams hyd roller lifters. The engine is topped off with Performer
RPM cylinder heads and intake. We also used one of our custom 4150 1"
spacers with the 950 cfm quick fuel carb. The combo pulled 11" of vac at
850 rpm! It made 558 hp @ 5400 and 583 ft lbs of torque @ 4500 rpm. ALL
ON PUMP GAS!!! Watch those brand new Doug's Headers turn blue on the pull.
