Is it normal to have a rough edged crank, like some one sanded all the edges?

The crackshaft is not smooth. it's cast. Only the journals should be perfectly smooth, so if it's a journal, no that isn't normal, if it's a counterweight, sure, don't worry about it.

OK, good, it was just one of the counter weights. I guess I can reuse it then.

if u feel like balancing the motor sand all the counter weights down and remove the casting lines then have the crank balanced it will provide better aerodynamics when it spins..

i can elaborate alot of this it is also called knife edging by some people...

For auto I wouldn't bother. Your only reving it up to 6500 RPM. You'd only be wasting your money. I didn't balance mine and she runs silky smooth all the way to shift.

Don't waste money and things you don't have to, especially if your going to boost.
