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.

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.
1968 Firebird First Run
Here is a short clip of of my 1968 Pontiac Firebird about an hour after the first startup and cam break-in has been performed. I have been working on it for 4 years and this was it's very first day running. It has a .030 over pontiac 455 in it with a Comp XE274H cam, ported 6X heads, custom GM intake, Hedman headers, holley 770 carb, Muncie 4spd, 3.08 posi, and Spintech 3" Exhaust with X-pipe,Sportsman XL mufflers with dumps. I am a happy man. It runs great and sounds fantastic.

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

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.
