I'm new here, I am partially disabled, and bought a mint '88 Crown Vic, I love this ride, it has a 5.0 EFI that is in mint condition also. I want to know how I might squeeze another 40-to-50 horsepower out of this motor, it flies on level highways and is a bit sluggish when passing or going uphill. I DO NOT wish to tear into the motor, I just want to know if I can add or bolt-on this extra power. Your experienced advice is much appreciated..........Thanks........Redlew

 

Maybe Headers, and dual exhaust with high flow cats. 5-15HPs maybe 20, but not 40-50, and would cost more than car.[&:]
