Default Max Rpm

What is this max I could spin my motor to I am building a 355 forged pistons and rods stock crank fully balanced studed 2-bolt main. I wanted to turn around 6700 Rpm but if its to high for the stock crank I will probably turn it down a little

Depends on your Cam..I am turning up to 6100RPM, then shifting. That's just how the powerband is.

Depends on the cam and valve springs. I have the limiter in mine set to 6900 and it will hit it quick in the first 2 gears, then the 3rd is a little more controlable.
My stock motor saw over 6000 more than once, burnout boxes are fun.
