Jim D | Gimme a Brake

Bought the car in 1995 after 21 years of deep storage. The car was complete except for some missing trim. The paint was tired so we re-sprayed it the original color. We've done a number of projects on the car, including a completely new suspension, belts, hoses and gaskets. We replaced the carpeting, wheels and tires. All of the chrome pieces of interior trim were refurbished and the carburetor was rebuilt (original 2-barrel Stromberg). The motor is the rare 273ci, which is adequate, but the car could use more power. We're looking for performance mods for this motor, which are pretty hard to find, but it would be a shame to remove the original, numbers-matching motor to get more power. Any input on good mods for the 273 is appreciated.
