While Professor Fate makes a good arguement, and the (light) press fit is indeed important, loctite will solve that problem as long as you can't wiggle the gear on the shaft. That being said, Chevies have the same size shaft and use a 3/16" pin, as I did some time ago. The shaft has plenty of "meat" for it. An alternative is to reinstall another 1/8" roll pin and another 180* off about 3/16" - 1/4" away from the original. This will make installing a new gear difficult in the future, however, unlike merely installing a 3/16" pin. BTW, this is a common problem when running a hv pump.
Another thing I noticed...most roller cams require a bronze cam gear, as the steel in a roller cam is so hard it wears out a standard gear. If the gear on your cam is removeable, it's probably a standard gear; otherwise, I suggest buying a bronze gear and installing a 3/16" pin as suggested above.
