360 Redline

In general, a safe RPM is 6,000 rpm and basic street red line is just that with a more amp'ed up build going another 500 to 6500.

Red line is determined by cam profile, valve train stabilty and rotating assembly's weight. Stroke is the other, but it is a known. Once you change one of the parts, ie; upgrade, the red-line changes.

Rather than start with what is a 360's red line, start again with what you want to do and work with the materails you can get to make it work.

Ultimate is generally @ 7500, while you can raise it higher, it is just a simple matter of dollors needed to be spent on it for a higher rpm ceiling.

NASCAR trucks go to 9500, or was that...er, never mind...big pro teams spend big for big rpm's....
