How do you match the square notch in an aftermarket harmonic balancer (ATI, powerband...) in the crankshaft? And does the new square "pin" come with the harmonic balancer?

Thanks!

installation orientation is any way you care to install it as the ATI hb is neutral balanced. does not come with a key for the keyway as your crank has not been machined at the factory for a keyway. you can order the ATI pinning kit if you care to and cut an extra keyway in hb so that it may be double pinned. single or double pinned your choice. if supercharging you need at least one pin but your already their so do two.you are able to order from ATI double keyed or get the extra keyway cut locally

the crank has a dot stamped into it TDC if your good put the keyway in line with the dot and you'll be as close as your going to get
