I'd ballpark 5500 rpm....and you're probably better off (speed wise) to shift it around 4500'ish for maximum speed (just a ballpark) since you will be making less horsepower when the engine is revved up to 5500 rpm.

If you have a stick shift car & like to rev up motors high, then definitely install an rpm limiter. I blew a motor missing a 2nd to 3rd gear shift many years ago.
