Pontiac 455 duet
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

1974 Pontiac LeMans GT red
I can't recall seeing a LeMans GT..but here one is..and it's for sale! I
really do like this style Pontiac....and this looks like it would perform
very well on the street! GTO was now almost history...the last year for
it, so this car helped bear the performance mantle for the division.
Performance plus luxury...a nice combination!
