I've had mine for 15 years. It's in very good shape as I've kept up with repairs. I had the car carburated. A remanufactured 318 was put in a year ago. Over the next couple of years I wish to moderately customize it e.g. install more ergonomic seats, 17 or 18 inch wheels, and get more power out of that 318. I know little about engines. What would one do first, second, third, etc. to get more horsepower?
