well, most ppl will use whats called a mixer, (propnae carburator, but you can inject it into each intake port, though i have been re-thinking this idea, as the lp has a longer time to mix with the air if injected in the mixer as opposed to right b-4 it goes into the cylinder, that is unless it was on something like the dohc 4.6 V8, where the injectors are aimed right at the intake valves, so the vaporization is awesome, though LP gas is quite cool, specially when that tanks been moving it for a while, so you may get an adverse affect by cooling that hot surface. guess the best way to find out is to try it....:S
