I just did a search on GL for the word "propane" and got 150 hits. Granted, a number of them were about propane heat, but at least one thread with the info related to what you are looking for was right on the first page.

I lived in Ecuador for 2.5 years. Secretly, a few people ran their vehicles on LP gas since it is subsidized and cheap, way cheaper than gas. I saw 3 different vehicles, 2 that could run on LP or gasoline per selecting. The carbs. were ordered out of the USA. They had to adjust the timing to prevent pings, but all in all, they were having no trouble running pre-80s big block V8s in trucks up and down the mountains with propane!

I have been running it for 2 years now,my first year I was running rebuilt impco stuff and had a few problems ,I read somewhere not to screw with rebuilt parts because they are tempermental so I bought new components and have not had a problems since.There is no way I would go back to gas only,I am switching to dual fuel just because it is easier to get gas for running easy trails and the road,also it will give me a backup so if one or the other systems fail.I got my brother to switch also and he seems happy that he did it.I do not know about fuel economy because I only ran my rig 1 time with gas before I switched over,but I did notice a power loss,as did my brother.Comparing to the other rigs I run with I would say I get a little less fuel economy but I wil pay that price since I do not have carb or electrical(fuel injection) issues.

How is it for the cold weather? starting it and running it. Does the cold effect it at all?

I've never heard anyone claim better gas mileage.

ITs generally ~10% drop in 'mileage', with a corresponding drop in power, depending on how well your engine was running before.

You should be able to advance timing a smidge to get you closer to MBT.

Yeah, there are certainly things with an engine built for propane to make up the power/efficiency (timing as you mentioned, and comp ratio), but apples to apples, without tweaking, its a loss.

I have not noticed any issues with cold weather but,to be honest I do not run much in the winter.It does start everytime I try, no matter the temp.I plan on eventually building for the propane,right now I just run a well used 350.
