Re: 454 TBI mpg
The TBI engine is no better than the carbureted engine for fuel efficiency or performance, and in fact is often worse. The TBI engine is in fact the exact same engine as the old carbureted engine, except that in most cases it has an adapter and a 650 cfm fuel injection throttle body instead of a 750 cfm Q-Jet.
The Vortec engines are light years ahead.
