Like one guy said, put a spark plug hooked to a Model T coil in exhaust pipe(s) and pump the accelerator (on carb equiped vehicle) a few times to load the exhaust w/ fuel, then switch on the coil. Guy in HS did it w/ his '50 Ford, shot flame 2-3 feet.

They also have a mod that you can add that puts out a fog of white smoke, personally if I saw that I wouldn't be impressed but concerned they had head gasket blown...LOL!
