    The damn thing will run with the spark plugs wires crossed.

    Note to self: #3 and #6 are on opposite cylinder banks!

    (I was soooo careful swapping distributor caps yesterday, really I was ... oops.) Spent a coupla hours dinking with the plugs, timing and the carb, only to come to realization that the backfiring and lousy performance above, say, 1500RPM, was entirely due to some idiot (me!) dorking up the firing order.

    Ah well, easy thing to fix. Swap the two wires at the dist so they're in the correct order, and she runs like a bat out of hell. The SBC400 is a wonderful thing.

    Now if I only the stop-power (brakes) were par with the go-power... this is on the Chalet, so stopping the extra weight/height is ... fun. ;-)

    You always start with 1 and you have 8 cyilinders.
    So that is 18. Times 2 is 36 times 2 is 72.
    So you have 18 36 72. Now that leaves 4 and 5. Put those in the spaces so you end up with 18436572. This is how I remember it. But then again I don't use the distributer anymore, because I have a computerized, 4 coil ignition system, with the cylinder numbers on the coils.
