wow thats a lot of info, the reason my buddy wants to run the propane is that it is already on his truck, so rather than buying a gas tank and a carb and all that it is easier to keep it on propane. we asked around at the racetrack and people told us to use a bigshot kit, and to be sure to add more propane when the nitrous kicks in, same as with gas. my personal experience with propane, i had an 83 gmc dually 454 4 speed just propane. set proparly, milage didnt drop power didnt drop. shop that converted it said power would be within 5 percent up, down, sideways when converted right, timing needs to be different, use a different spark plug, propane runs hotter {i think}. That engine had over 400,000 kms on it and still ran like a top. i think if a guy built an engine for propane he could get even more benefits. lots of people say propane will freeze up but it never happened to me, apparantly if its colder than -60 deg celcius it could. the other trouble people have is trying to run gas and propane, then you cant in my mind adjust the engine to run right on either so your always splitting the middle. thanks for all the input T.J.
