Really don't think this belongs in the highly technical section, but it is relatively easy to do. Does the engine in your truck have a carb? If so it is easy to do. You will need to tune the carb so it is running really rich. Next drill a whole the same size as the spark plug you are going to use in the end of your tailpipe and bolt it in place. Now you will need a coil, motorcycle or car/truck coil is fine, just the kind that is used on the older types of cars without the electronic/HEI ignitions. You will also need a momentary switch, same type that your computer uses just a heavier duty one. Mount the switch inside of your car and run a wire from it to the postive terminal on your battery then from the other post on the switch run a wire to the coil. Now hook the other terminal on the coil to the negative terminal or ground it the car the car frame really good, then just take a spark plug wire and attach it to the coil and hook it to the spark plug in the tailpipe. All you should have to do is rev your engine up, then let off the gas pedal and hit the switch at the same time as you let off the gas. If everything works right, you should have a flame coming out of your exhaust. If you don't have a carb, it becomes a little trickier to do. Some people can just rev their engine up then let off the gas pedal and it runs rich/hot enough that it will light without a spark plug.
