After almost 30 years, I am finally getting around to a semi-custom restoration of my 1959 Willys Station Wagan. I intend to keep the original L6-226 but would like to increase its power to something beyond the stock 105 HP. After-market bolt-ons are not an option so it seems that I would need to find someone willing to take this on as a project. Before I go any farther, I need to say that my wife is a bit skeptical about, let's just call it, this idea.

I understand how an engine works but don't have a clue about how to determine what can or cannot be done to an engine and still have it be dependable. Performance areas that I have considered include, increased displacement, increased air flow efficiency, increased combustion efficiency, and increased RPM.

Am I dreaming, thinking crazy, or is there life beyond 105 HP?
