I'm just curious and it's a difficult topic to search the archives for.
Has anyone here done it? What's the consensus? Propane conversion is mentioned in the tongue-in-cheek thread "you'll get 8 to 10 MPG depending on whether or not you pull a toad"
I believe LP and NG power will take off in the coming years, right after the economy recovers and gas goes back to $4/gal.
My revcon really does have just 26K miles evenly spread out over 37 years so it might be a good candidate.
Likewise, the guys on the Old Engine forum say my original Onan CCK is a great engine and worth converting to propane.
I don't think my travels will ever see the real mountains on the West Coast so if there is a power loss I can live with it.

Dave,
Jim B built a dual fuel (Gasoline & LPG) powered Olds 455 for a guy in
England.
I have a Caddy 500 ready for reassembly sitting in Double Trouble's storage
facility in Houston that will eventually get shipped to Australia where it
will run on Autogas. Autogas is a 60-40 mix of LPG and Butane sold
throughout Australia.
Here petrol is currently selling for around $1.20 AUD a litre whereas
Autogas sells for $0.62 AUD a litre.
Autogas has an octane rating of around 98 RON and will support a compression
ratio 10 to 1. Well I sure hope it will as that's what I've set up the Caddy
to run at!
I just checked the prices of LPG at Flying J and it's MORE expensive than
gasoline! I'll bet dollars to donuts that when gasoline is at $4.00 a gallon
LPG will up at the same price. The reason LPG is cheap is because it doesn't
carry the same level of taxation that petrol does and Australia has
plentiful supplies of LPG. In fact, we use only 60% of what is currently
produced with the remainder being one of the nation's export success
stories.
IMHO in the USA converting to LPG is a financial no-win situation! Frankly
considering what I've spent so far on the Caddy 500 the same is probably
true. I'm only doing it as Gene Fisher says "because I can!"

A quick search of the web confirmed what you just said so my interest at this point is largely theoretical with an eye to the future.
Propane is what we are discussing now but the conversion would work for CNG as well. I believe we will head towards the Pickens Plan (but Ole' Boone won't get dredit for it)
I think it's quite possible that gas, LPG and CNG will reach a simalar price point not long after the economy recovers.
Is there consensus on whether or not it's a lot better for the engine?

I believe I have read that ALL of these are
cleaner-burning than gasoline.
