I'm thinking of reviving my '67 K/10 Suburban to run on propane. It currently has a 454 that probably needs rebuilding. I'm also thinking of building up a 292 L6 to swap in, instead and maybe turbocharging the 292. I want dual fuel capability (gasoline 91-89 oct/ propane) and if possible, switch-on-the -fly capability. Is this all possible?
