Ok here's the quick version.
Aquire a Hei distributor and a 12v electric motor(a heater blower motor works well). Mount the electric motor and dist. on a board or something so that the motor can be used to turn the Hei. I hook them together with a piece of house and hose clamps. You will have to take the gear off of the dist. to do it this way. Run power to the motor and to the Hei thru a switch. When the switch is on the Hei should deliver spark. Run plug wires off of it down to spark plugs in your tail pipes.
On your engine, get a "naturally open" switch to tie into the ignition on your cars engine. This switch will kill your engine when pushed in. You use this switch to kill the engine temporaly. Sometimes you have to do this when your trying to get your pipes to light.
You need to run a choke cable on your carb to flood out your engine. You have to flood it out before it will flame and you have to do it with the engine rpms up some. Everyone freaks out over this method but its the safest and I know guys who have been doing it with the same engine for over ten years. Just change your oil as it needs it and use common sense.
