This is the largest cam and build ive ever done. So like i said it could all be in my head what i think i am hearing is as its idleing there seems like a quick short hesitation in the rythem. From time to time.
Firing order 18436572. Notice that 2 cylinders on each bank fire consecutively and the rest alternate from bank to bank. Sometimes at idle you can hear or feel that and think it is a miss. In other words - left right right left right left left right.
How fast is that idling? Might be a bit slow for that size cam.
