Wander (propaneburner): You might recognize my name as being Dutch. It's Teunis Wyers. I'm building a 292 six to run on propane right now. Before you decide on a piston, you need to decide on turbocharging or supercharging, because that has a big effect on what compression ratio will work. I'm going without any boost, so I want a fairly high compression ratio. You can't get there with either the stock pistons, that have a deep dish in them, or the LPG ones, that have a dish also. My current plan is to use a TRW piston designed for a Ford tractor that has a flat top, and is close enough that my engine man can make it work. They will cost about $350US for the set. If you want more details, let me know. Phantom Shafter
