I'm not saying your 455 is in its worst form. Was just using for conservative numbers.
In reality the post 1971 cars were rated at Net versus Gross Horsepower.
The Net Horsepower as the engine in your car is burdened with various engine-driven accessories, ranging from the engine's own oil and water pumps and generator/alternator to the power steering pump and air conditioning compressor, each of which consumes a certain amount of power. An engine in a passenger car also has mufflers and an exhaust system , rather than low back pressure of a huge dyno muffler, ignition is retarded to prevent detonation with pump gasoline, and the carburetor or fuel injection system are aimed at fuel economy and driveability, not maximum power. The gross rating reflects none of these losses; it represents an engine's theoretical maximum output under ideal conditions, not how much power it actually produces when installed in a car.
While the smogger engines did suffer from significantly less compression ratios they did have an 800 cfm carb over a 750 carb to make up some of the difference.
The engine in a Regal should produce a respectable quarter mile time depending upon how sticky are the tires and if there is posi-traction that is working correctly.

Not yet lol...I bought the car like...23 days ago, and I still don't even have it...I'm flying out tomorrow to get it, because for some reason no one could get a truck out there to ship it

Well I got the car back, which was 1000 miles, and it ran out pretty good, and got between 17.5 and 19.3 miles per gallon
