I have no shame... So what should a b303 feel like? What should my timing be set at? I've read advanced all the way, I've read stock timing. It shakes the whole frikin car and backfires until warm at 14 degrees. I've never had a cammed car before. Should it shake enough to see the motor shake, the gear shifter shake, and rattle the interior at idle? As in I can feel it in the seat. The hood moves when it's up. I need to know so I can smooth it out if it needs it. I've been searching youtube but everyone posts videos of their exhaust pipes.
