[QUOTE="xblitzkriegx, post: 16434042, member: 105608"] That particular car, no. However, it's pretty common and perfectly acceptable since the rules allow it. I'm not infering that the owner is cheating, just that the engine isn't as it left the factory for that setup. The W-30 cam specs at (0.006) 328/328 .475/475 on a 108 overlap for the 4 speed cars, the auto cars got a 286/287 .472/.472 cam with 57 overlap. The GS-X got (0.006) 316/340 .490/.490 on a 91 degree overlap. You can tell right away that an auto W-30 doesn't stand a chance against a GS-X car based on cam alone. The car above most likely uses the 4 speed cam which requires a factory special QJunk carb. In top of that, it's probably running more compression. That car isn't typically what a W-30 car usually runs. This is what a typical W-30 should be running [MEDIA=youtube]wMwJH0z9btY[/MEDIA] [/QUOTE]
