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 & easy.
1969 pontiac lemans 455
Here's a video of my 69 lemans with rebuilt 455 bored .040 over (464), speed pro pistons, edelbrock rpm camshaft, 6x-8 heads ported, comp cams rollertip rockers, edelbrock valve springs, procomp intake, 750cfm edelbrock carb, and flowtech headders. This combo makes great power and I love the torque this monster makes. Next upgrade will be edelbrock aluminum heads to really wake this beast up! Please comment on engine combo, body, and suggestions. Thanx
