how hard and $ is it to install flame throwers on a small block ford with open headers, one per cylinder? i am running 8 custom laser cut pipes with flames cut in the ends
i seen a guy take a gm hei distribitor 8 plugs a wire set and a small dc window motor and he just pulled the choke flipped the switch it bellowed flames like crazy ,its kinda hillbilly but hey some of the funnest things in life are too so just my 2 cents
i dont think that drawing will work...... like that you will only get one single spark when the flame thrower button is released, which may not lite the fire.....
you need to intterupt the GROUND signal to the engine coil (being the points) and send that to the flame thrower coil which is powered with ignition power, this will give you the same number of sparks per revolution for the whole engine, to the spark plug(s) in the exhaust.
use the relay to do this, splice into the wire that goes from the dist. to the engine coil.
hook the wire that comes from the dist to the common terminal of the relay
then hook the NC relay terminal to the engine coil
and hook the NO relay terminal to the flame thrower coil ground, in my set up i didnt even use a ballast resistor and worked great
and both the engine and flame thrower coils will be powered constantly with the key in the ON position
and a coil takes a very small amount of power to run, so there would not be an issue with running a whole gammut of coils for multiple pipes
hope this is clear..... ill help as much as i can, because ive gotten a lot of joy from this simple modification, and i just went to pick a part and got the stuff dirt cheap, the only remotely tricky thing is finding a plug wire that goes directly from the coil to a spark plug.[cl

this might help a bit. I bought a kit before I found a diagram to DIY. make your own for $10-20 if you already have a couple old coils, plugs and plug wires laying around the shop. just a 5 terminal relay, little bit of wire, a couple coils and wires, 2 plugs and 2 spark plug anti foulers. you can cut off the ends of the foulers and weld them in exhaust pipe. I have 2 coils and plugs running on one relay. I get about 4-5 feet of flames from the end of open headers. my headers end right under my window so yes, I did lose a little hair trying it out the first time and looking out the window.
love it. do you have to rev it up an pump the heck outa gas pedal[cl like i do my current kit?
