When I had the gear on my MSD distributor changed to be compatable with the roller cam, the guy said the gear fit was too tight. He reamed it out (for a "light press fit") and pressed it on and installed a new pin.
I was not comfortable with this so I called the MSD tech line. After talking to the tech guy he told me that FORDs must have the gear PRESSED on. A tight fit is required. I sent the distributor to MSD and they replaced the shaft and installed a new steel gear for me for free !!
I think the tight press fit is needed becouse the pin alone isn't strong enough.
