Lax swap!!! For economy I vote for a junkyard 4.8 or 5.3 backed by a 6 speed and decent rear gear. Maybe 3.08 or 3.20's? Eliminate all smog stuff you can and have it tuned for economy at cruise and power when you need it.
Or is reusing the original engine eliminate all the smog stuff and add a better flowing intake/carb with better flowing exhaust. Manual trans conversion.
