If you go with a rebuilt make sure it has a NEW starter drive. The rebuilt starter drives are notorius for premature failure and are found in the cheaper rebuilt starters.

As far as I recall, there is no difference in the 427 and 428 starter drive tooth count.

Another thing I didn't like about the "geared starters", like Power Master and others, is the slower cranking speed of the engine. My motor starts up quicker with an OEM starter because it cranks faster. If an OEM is having trouble cranking your motor over it's likely because your base timing is to far advanced.
