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.
Pontiac running 2009 big cam idle
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.
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).
1976 Pontiac Trans Am with 455 testing out the new engine
In car video of a 1976 Pontiac Trans Am with a 455 in it. This has one of
the comp cams extreme 276 cams in it. Probably the most potent cam I have
used in any of my pontiac engines and still maintained excellent street
manners. Unfortunately, one of the rod bearings did not hold up as well.
The purpose of these runs was to try to get the car to blow up if it was
going to. It has a slight noise in it that I couldn't figure out. Wound up
being top rod bearing on number 7. Was torn down never to be assembled
again. Car was awesome though. Sold to Volo auto sales in Chicago. They
painted it and sold it as a 50th anniversary clone car for $20k more than
they paid me for it.
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.
Pontiac 350 - 350 Horsepower For Less Than $500.00
A short video describing the modifications done to the 65,000 original mile
Pontiac 350 engine in my 1975 Formula. Using heads, cam, pushrods, rocker
arms and an intake that I had laying around, this Pontiac 350 developed 353
horsepower and 385
lbs/ft of Torque, for less than $500.00 invested.
