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.
Custom 1972 Pontiac Firebird - V8 sound!
Jamboolio records a fully restored 1972 Pontiac Firebird with an 350 cid
5.7L V8 engine and a stunning new paint job.
The monstrous hood scoops and huge air vents added to the all black
exterior makes it a very bad-ass looking muscle car beast! The Exhaust sound is pretty awesome too! Enjoy.

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 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.

first startup and cam break-in has been performed. I have been working on

intake, Hedman headers, holley 770 carb, Muncie 4spd, 3.08 posi, and

and sounds fantastic.
'72 Pontiac Trans Am 455 HO Burnout
As I was walking along the road I was passed by the car followed by the
mysterious fog... I wondered what that might have been...
The answer is... the Bandit and his T/A are back in town!!!!!!

This is a video of the 1979 Pontiac Trans Am H.O. that me and my dad built.
Very powerful car. It has not been Dynoed yet or run on the drag
strip. But it has done a few burnouts ;)
68 Pontiac GTO Car Craft Dyno Challenge 7/17/09
68 GTO on the Dyno at
2009 Car Craft Nationals. Car made 488HP and 454FTlb torque. This burgundy
GTO is equipped with a 455, 72cc Edelbrock heads, and a NOS shot I forgot
how much. TH400 with 4.11 posi. Sounded great through open headers. Owned
by a nice guy from southern Minnesota.
350 with World heads
.040 over 350, speed pro forged pistons, rebuilt bottom end, double roller
chain (note the green over spray lol, it was dark when i painted it, and I
probably had a few too) World Sportsman II heads, orginally came with
umbrella seals and shitty crack prone single valve springs, now have
positive seals, comp dual springs with a dampner and 10degree locks.
Performer Intake, with 600cfm Edelbrock, Comp XE274 cam, Comp Pro Magnum
rockers 1.52 ratio. 9.3:1 compression, TCI Rattler balancer...and thats
really all for the motor...its going in my 82 Monte Carlo, no rust, still
needs body work, interior work...and well...it just plain needs work.
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.
Big Burnouts: 1964 Pontiac Catalina Safari - /BIG MUSCLE
If you haven't figured it out by now, we love wagons on this show. To some
they're a misunderstood breed, but to those in the know, they're amazing.
Not only were the wagons of yesteryear known for their styling, but their
capacity to haul as much cargo as a modern day pickup. This 1964 Pontiac
Catalina Safari started off life as a Police Wagon, but was transformed by
its owner into the kick-ass, tire-shredding monster you see here. With a
Nelson Racing Engines 468 cid big-block under the hood, some updated
suspension bits and a killer look, this big green machine is
outside-the-box styling at its best.
