The petronix is a pretty dang good bang for the buck conversion for stock to very mild builds... the only downside, or rather, the only issue I see with customer's stuff is when guys use them on wore out or just plain jacked off distributors and then you have money into a distributor that may spark better, but doesn't work properly, be it erratic timing or non-functioning mechanical advance. So make sure the distributor is in good shape FIRST... if so... then cool beans and order the conversion.
