Re: Firing order for a 71 BB with HEI
The FIRING ORDER is the SAME. 18436572, just as stated before.
I think where you're confused is that the #1 terminal on the HEI cap is moved over a bit from the #1 terminal of the points distributor.
Install the HEI distributor so that when it is seated on the manifold, the plastic connector where the three wires come out of the distributor base (which then lead up to the cap) is straight forward. The rotor points at #1 on the cap, which is just where the Chiltons shows it--2 terminals over from the power/tach connector. Align the pickup coil teeth with the reluctor teeth by slightly moving the distributor body, while the timing marks on the damper are set to whatever you want your initial timing to be. (so set the damper for 8 degrees advanced if you want your initial timing to be at 8 BTC) Tighten the distributor and fire the engine. You should be within 1 degree of your target when you've had some practice at this.
