    horsepower question

     



    I have a 400sb out of a '71 2 door caprice. It's a 4 bolt main with a K@N filter (free) and dual 2" straight pipe. I know it's not much to go by but what would an estimate on horsepower be?

    Probably 225-250 hp and close to 300 ft lbs of torque, just a guess.
    Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.
