I'm sure this question has been asked many times. Im also leaning as i go so bare with me. I have a 53 chevy truck with a 58 235 motor, its running really rough and i want to recheck the timing with a timing light. What mark do i use from the flywheel? I know there is a triangle and bb. Do i have to mark it with a chalk? Can someone please go over in detail to successfully accomplish this, thanks
