The LeMans (on the left) has a mild, non-rebuilt 455 with ported & polished 6X heads, c. 9:1 compression, Edelbrock Performer intake, Holley 800 Street Avenger, Comp XE274 cam, making maybe 300-350 horsepower. The Grand Am (right) has a .030 over 455 with Edelbrock heads (87 cc chambers), 10:1 compression, same Comp cam but with 1:65 roller rockers, slightly better Exhaust (H-pipe), Edelbrock Performer RPM intake and Edelbrock 750 carb. About 500 horsepower at the flywheel. The heads make all the difference. The Grand Am has the Flowmaster American Thunder Exhaust system, which has the 50-series mufflers. LeMans has a Summit Exhaust system, which was cheap and went on nice & easy.
1974 Trans Am Super Duty 455 Four-Speed FUN
This is a very rare 1974 Pontiac Trans Am Super Duty. Less than 1,000 of
this 455-powered, specially built monsters were produced from 73-74. Today
they command ever increasing prices approaching six figures.

Late-Model Camaro Z28
messing around with a classic 455 powered GTO... The GTO jams it and then
one of the passengers thought they were being tailed by an undercover B4C
Camaro holding a radar
gun (video camera, lol)... you can see the nervous, unsure look on his face
as we roll beside... then the total relief once he recognized an old friend
behind the wheel...lol.
This was shot many years ago with an old analog camera, so apologize for
the poor quality...

arms and an intake that I had laying around, this Pontiac 350 developed 353
horsepower and 385

1968 Firebird First Run
Here is a short clip of of my 1968 Pontiac Firebird about an hour after the
first startup and cam break-in has been performed. I have been working on
it for 4 years and this was it's very first day running. It has a .030 over
pontiac 455 in it with a Comp XE274H cam, ported 6X heads, custom GM
intake, Hedman headers, holley 770 carb, Muncie 4spd, 3.08 posi, and
Spintech 3" Exhaust with
X-pipe,Sportsman XL mufflers with dumps. I am a happy man. It runs great
and sounds fantastic.
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).

1964 Pontiac Tempest, 2dr Post, 455 .040 over, 4X heads, Comp XE274
cam,Performer RPM manifold w/ Edelbrock Performer 800cfm, Full Pypes X Exhaust with RacePro mufflers.
Engine has Holley 3130/750 now and different timing set up. Made huge
difference. I could never get the Edelbrock carb to work right. And yes
the Mr Gasket header gasket on the driver side was leaking just 40 minutes
after break in.
