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.
'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!!!!!!
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.
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.

.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.
Pontiacs for 1964
John DeLorean replaced Pete Estes as general manager, and he continued the
same emphasis on performance that Bunkie Knudsen and Estes had begun.
The big news for 1964 For 1964, the Tempest and LeMans' transaxle design
was dropped and the cars were redesigned under GM's new A body platform;
frame cars with a conventional front-engine, rear-wheel-drive layout. The
most important of these is the GTO, short for "Gran Turismo Omologato," the
Italian for "Grand Touring, Homologated" used by Ferrari as a badge to
announce a car's official qualification for racing. In spite of a GM
unwritten edict against engines larger than 330 ci in intermediate cars,
DeLorean (with support from Jim Wangers from Pontiac's ad agency), came up
with the idea to offer the GTO as a dealer option package that included a
389 ci engine rated at 325 or 348 horsepower (260 kW).

Camaro Z28 messing with 455 GTO on the street
Late-Model Camaro Z28
with bolt-ons messing with a classic 455 swapped GTO.
The GTO jams it and then one of the passengers thought they were being
tailed by an unmarked B4C (special service police) Camaro holding a radar gun (video
camera, lol) notice the nervous and unsure look on his face as we roll
beside, then his complete and total relief once he recognized a couple old
pals in just a regular Camaro, lol.
(This Camaro made 280hp
at the wheels and ran 13.1 at Mason Dixon Dragstrip)
This footage was shot way back, many years ago, with an old junky analog
camera, so apologize for the poor video quality.
