Default valve spring rev limits

search didnt pull up much but i was curious as to what valve springs were good for what RPMs??

i have BC stage2 cams with their valve springs and ti retainers on order along with manley rods and cp pistons to follow. the bottom end will all be balanced....from the crank pulley to the comp clutch. so i was curious as to who is running BC valvetrain and what RPMs they are running at safely.

Oil pump will let go before you max out the valve springs.

If its a street car and doesn't see high RPM that much you will be fine. But anything with power over 7500 for extended periods is asking for a blown up oil pump.
