A freind of mine is putting a 454 with alum. heads into his Wrangler and he is triing to decide what to do for fuel. He is looking at either the Edelbrock TPI setup or, going propane. Is anyone running propane with a big block if so how is the performance I have heard that your throttle response can be crappy, and how long can you run on a tank, say an eight or 10 Gal. one. Any help would great thanks John.
