Never heard this. Lots of taxis and fleet owners convert for the savings. Propane is cheaper but has less energy, but it can be more efficiently burned. (less waste) Propane has a much higher octane rating so to increase the efficiency the compression should be raised. 10-11 to one wouldn't hurt, and will bring back the performance of gas using a cheaper fuel.

I have had propane powered vehicles in the past.  Less power and I did not like the hazards of driving a vehicle around the streets of Phoenix that was powered buy propane.  Propane is heavier than air so when you have a leak it pools under the vehicle or on the floor of the vehicle depending on where the leak is.

The amount of power a piston engine can make is limited by the amount of air you can get into the cylinder.  You have to maintain a burnable fuel to air ratio.

With gasoline, some of the fuel is still a liquid entering the cylinder.   The liquid takes less room than the gasoline vapor.  More air can get in to the cylinder, so more fuel can be burnt.

With propane all the fuel is a vapor, entering the cylinder.  That displaces some air that could enter the cylinder.

 

The heavier the refined fuel made from crude oil, the more potential chemical energy in a given volume of fuel.  Diesel weighs more per gallon, and that is part of the reason a diesel engine can make more power than a gasoline engine, the other being higher compression.

 

Propane is lighter than gasoline.  Less potential energy per gallon of propane.

how much would I shave off the head ?

 It is also prone to freezing up in cold weather.

Hard starts when cold .

 All bad in Minnesota.

Has issues at altitude.

Not the easiest thing to find in some rural communities.

If you run out of gas , your screwed . Etc.

 I have run it off road on more than one rig.

I found that all of the above issues made it not pencil out and have converted back to gasoline.

Hands down... gas is the most concentrated energy source there is. Simple, easy to use, easy to store/transport, well used, and an infrastructure set up to supply it anywhere. Agree hard to vaporize when cold but great for taxi and large fleet vehicles that only get shut off to service them. DD? depends on longitude and altitude.
