I'm looking at a 455 that's run only on propane. It is relatively low miles (around 70K). What problems are likely? I've heard that heads could be an issue in that 70s engines aren't likely to have hardened valve seats. I'm thinking the gas system (fuel pump, tank, lines) could also be an issue. Anyone with experience in this area? Advice? Thanks.
