5.0 roller cam engine, had a HO fuel injection manifold and TFI distributor. Swapped to a 74 points distributor, Edelbrock Performer 289 intake with a 600 cfm Summit 4bbl carb. I was under the assumption that all roller cam motors used the 351 firing order, but have just found out apparently they don't. There were a few used in Lincoln Town Cars, Crown Vics, and Mercury Grand Marquis that used the old 289-302 firing order.
I have been trying to fire off the Lincoln all afternoon, no luck. I can make it spit out the carb or the exhaust or both, but not run. I tried the old firing order once, but must have had #1 off, it never fired. Pulling hair here!
Went back just now and looked at old dist cap and wires, sure enough I marked it before I pulled it, and IT DOES USE THE OLD 289-302 FIRING ORDER! Gonna try to rewire it again using the old order tomorrow or Monday and try it again.
I was told when we got the truck that I took the engine out of that it came from a Mustang, well, maybe the FI did, but now I'm thinking the long block came from a Town Car or Crown Vic. I love my Fords, but they sure did some weird $hit sometimes!
If going to the old firing order doesn't work, I'm totally stumped on this one.
