I have a 1964 Falcon two door hard top project car and I need help with a firing order issue. The engine is a 351W with 351W heads and intake manifold. I bought the car a few months ago and I have finally found time to begin the resto project. The engine was running only at high RPMs, but not great so I decided the first place to start was the points, condenser, distributor cap, rotor button, coil, plug wires and plugs. I changed the plugs one by one and the plug wires one by one and halfway through I realized the firing order relative to the distributor cap was not the same. I got frustrated and took all the wires off (bad idea) and wired up according to the stock intake manifold firing order of 1-3-7-2-6-5-4-8. I changed the oil and filter and attempted to fire up. The carb backfiring and shot smoke through carb. I researched the cleveland firing order and found this: 1-5-4-2-6-3-7-8 and the car fired up. I still had the low RPM sputter and this is more that likely the carb (Holley 4777) needing work. I would like to get a cam and intake, but the prob with the cam is that the cam that is in the motor has the cleveland firing order. Does this mean I have a cleveland cam and crank? Any help would be appreciated. THANKS!
