It is faster. By a decent amount as well.

My 550 at 6000’ above sea level ran 12.2@114mph in the quarter mile.

My wife’s 240, same day, same track ran 12.8@107mph in the quarter mile.

Her car is a good 400#’s lighter, so the 540 would likely be even bigger of a gap as it’s heavier than her 240. She also has the B58 motor as the 540.
