Question 302 firing order

Hey everyone,
I got the 302 in my wagon now and was wondering if someone could tell me if the firing order is the same on the mid 80's 302's as it is on the early 60's 289's. I have the wires set up 1,5,4,2,6,3,7,8 going counter clockwise. Someone please let me know if I got all bass ackwards.
Thanks,
Dragon wagon

I think they changed theit firing order in '85. It changed to 1-3-7-2-6-5-4-8.

That would be correct. My 302 based 347 stroker is 1-3-7-2-6-5-4-8 counter clockwise.

This is where it gets tricky;

The 5.0L uses the old 289/302 firing order 1-5-4-2-6-3-7-8

The 5.0L HO uses the 351W firing order 1-3-7-2-6-5-4-8

So you have to know what engine you have. The HO went to the 351W cam specs.

The 302 I put in is an '86 and it's not the HO. I used the intake, carb and distributor from my '63 289. Will I have to get a new distributor or will I be able to use the one I have if the order is different?

If the engine is not an HO (HIGH OUTPUT/MUSTANG-CAPRI), then your origional distributor will work fine (It will work fine on the HO-Just need to change the firing order on the cap).

What is the engine out of, a CROWN?



1986?

Does this engine have a roller cam or flat tappets? If it has a roller cam, you will need to upgrade the distributor drive gear.

It came out of a LTD.
To my knowledge it doesn't have a roller cam.

Be sure to check you cam follower type. They had a running change in '86 to roller from flat tappet.

I also have to double check the year. The car was an 86' but the guy I bought it from didn't think the engine was original. He thought it came out of a newer mustang. The code on the tag on the valve covers was 86 but I didn't check on the heads.

If it is 1986 and above, it will have come with EFI. The standard 5.0L throttle body will be on the driver's side whereas the 5.0L HO will have the throttle body on the passenger side.

The MUSTANG got rollers in '85 whereas the CROWN got them in '86.

Maybe this will help.

Yeah that does help. It was efi but I removed all that and put my old intake on. The throttle body was on the drivers side.
Thanks for the help!
Do you still want the efi from it very cheaply..

Not much value unless it was HO.

I would advertise it though...you might pickup a few bucks...
