What is the highest safe rpm on a stock ls3 without factoring in the rev limiter?

You also have to remember that Lambos and Ferraris all run flat plane cranks too. Thats where they get their high revs from. Fords new GT350 is running a flat plane crank and makes peak power at 8200.

Cam Ramp profiles, Cam specs, weight of valvetrain parts, type of rockers and a host of other factors all play a roll in what max RPM you can spin the engine. Most cams for these engines will make peak power between 6200 and 6800 RPM Shift points should be about 10% higher than where Peak HP occurs for best performance. Rev limiters are there in the event of a missed shift and are not to be used as a parade device. Yes believe it or not some cultures use the rev limiter in a parade. Ted.
