RH firing order 1-8-4-5-6-2-7-3. If you have a stock intake, you should be able to see the cylinder numbers embossed on it. Here's a rotation diagram, people get it backwards by looking at the pulleys from the front.

Ok. I changed my notes.
I don't have a repair manual for this engine. Can you get these thru CC? Thanks |

the order starts with 1 not 8 look at the repair manual in the reference section it's pretty clear on what the specs should be.

My bust. What I should have said was, 8-4-5-6-2-7-3-1 (COUNTERCLOCKWISE).
Yep, this all started with trying to get my carb dialed in after rebuilding it. I found my distributer loose in the process. I was on a bit of wild goose chase yesterday since my friend told me that the #1 was on the port....and the port side cylinders were 1,3,5,7. A small detail.....:) If the 8-4-5-6-2-7-3-1 (COUNTERCLOCKWISE) firing is correct, how do you set the timing? That is, what RPM's should I be at. I have it set to about 800 now but I still need to set the air/fuel mixture (just rebuilt my carb). I'm running at about 9 degrees right now. 6 degrees in seemed bogged down. At 12 it didn't start good warm. Any thoughts? Thanks for the help and the tips! |

that is the firing order for a RH rotation engine and not a LH rotation engine like he asked for that would be 1-5-4-2-6-3-7-8

According to my manual and knowledge you are correct on both. The cylinders are numbered 1 thru 4 on the starboard side (front to back) and 5 thru 8 on the port side (front to back). a$$uming "front" is closest to the driver's seat going "back" towards the stern. Hope that helps.

if it's a clockwise motor then someone as reversed the rotation of the engine or replaced it with a conventional motor. Look in the reference section in the PCM manual and it will list all of the engine specs.

I have a 351 in my 76 SN. What is the firing order? I think it's 1-8-4-5-6-2-7-3 (clockwise).
Also, on a ford, is the #1 cylinder the front starboard cylinder(driver side)? Thanks for the help |
