    Take a light and look past the distributor on the intake (the firing order is cast in). I belive it is (off the top of my head) 1-8-4-3-6-5-7-2 counter clock wise.

    I thought the 4.9 was gone by '97? Zipfast has the correct order.

    Sorry, I have two cadillacs, I meant too ask about the 1994, not the 97 since it has the Northstar 32v, thanks for the info guy's...'Henry
