I need a little advice. I just rebuilt my 289 .040 over with 302 head 63cc combustion chambers, flat top Sealed Power pistons, stock rods, roller rockers, etc. Put a Windsor cam in it, timed it using the 13726548 firing order. No Luck. Retimed it to 15426378 it starts but runs like it's got a miss. Any advice.
Getting tired of messing with it. Be willing to part with the whole car if anyone is willing to buy.
I think the illusive Firing Order that Ratter is refering to is found in the 83 and later Windsor engine. Particularly in the 83 V-8 Ford Fairlane. It switches cylinders 2 and 8 for a firing order of 15486372.
To also correct a misquote if I may. The Cylinders are numbered looking from the front of the car into the engine bay 1-4 on the passenger side 5-8 on the drivers side. Thanks for playing.
