Unless you are running a high lift camshaft (lotsa spring pressure) I would pass on any geardrive. They generate lots of harmonics that usually get absorbed by the chain and big spring pressure is what causes chains to stretch. Spend the money and get a good Rollmaster Timing Set with the German chain( they have red label and blue label sets, I can't remember which one is which, you want the German chain) and your good to go.
