Can a 28CI briggs flat head have more horsepower than a 31Ci motor I've listened to my motor on video with 31CI motors and the motor revs higher and the mower is faster than the other mowers, I'm just curious if my motor has valve work, cam, crank, rod, piston, and head work could it have more horsepower than lets say a 31CI with not the same mods?
