Your max rpm for your big block????

HEMIDENNY ...............
Just trying to see how high on an average, what people push big blocks to for rpm's with no problems.
I am building a 400 with a solid cam and want to use a high volume oil pump with a deep pan.
The only other thing i might do is install valve cover oil spray bars to keep the valve gear happy for those highway trips.
I always run low gears in my cars and have higher rpm"s all the time.
I won't go much past 6500 with the stock heads but when i go to a aluminum head i might want to bump it to 7000-7300 for shift points with install even more gear and converter.
