liquid propane injection

[mustangmike6996]

i really do not know where to post this.... i have a 69 fastback and i will be installing a 347 stroker or a 408 stroker.... i saw on SPEED channel that Mothers Polish had a Chevelle that was run entirely off of liquid propane injection and made something like 1000 HP... does anyone know where i can get the technical info of how these systems are setup or if i can even run a ford small block entirely off of propane???


or any helpful hints about propane cars would be nice....

Thats the 2nd time they had that Chevelle on, they have been changing and adapting stuff to get it to run right, the 1st time it was on they said they were having everything custom made in Australia and having the stuff flown in.

why propane? Its more expensive then gas....

Propane allows you to run 14:1 compression ratio or extremely high boost with no detonation. Farm equipment has used gaseous LPG or propane for years. The oil never gets dirty and the engines have very little wear on them. It is very low pollution, so it makes good city car fuel.

all the fork lifts in our plant run on LPG and there is a converted yard truck that runs on it too. there are several companies out there that will sell conversion parts. do a google search and you willl find them.

All this is true, but, for a street car it may not be as practical due to the weight of the fuel tanks and the limited availability of refueling. It may not make sense to take a cross country trip in a propane powered vehicle. I remember seeing some propane converted trucks back in the gas shortage days --- mid-70's.

well the only reason i was thinking of doing this is due to the gas situation... why spend 10k on a power plant thats going to eat gas at $5 a gallon when i can do something a bit different with a fuel that does not price jump like gasoline... its still just an idea tho... and since i have nothing done with the engine yet i might as well think about it....


i did a google search and couldnt find the specifics of how these systems operate. or what kind of plumbing needs to be run

They got all that stuff custom made in Australia for that car, it did not really run right after the first go round, so the episode you just watched was them replacing stuff to make it run. It seems like getting stuff from Down Under may be your only shot, I am sure it is extremely expensive, you might also try contacting Hot Rod Magazine for more info.

have you priced LPG and natural gas?? it's not much cheaper.

I ran a propane powered service truck for 5 years, when I worked for a propane company. As stated before the main benefits are clean burning, long engine life, and the ability for higher compression.

But for a everyday car it is really not feasible, as the tank say a 60 gallon tank like I had on my truck will be upwards of 150 pounds as it has to be made of steel for safety reasons. You will save bit of weight on the fuel itself since a gallon of propane is about 4.2lbs, compared to about 6.2 for gallon of gas (depending on the grade), but it won't make up for the tank weight.

Also, for a street drive vechile you must have a propane permit sticker for the vehicle, or at least that is the law in Missouri, but it may be different where you like.

They due burn clean though.
