I always used a 12.75 x 3.25w on mine.....
(i may have the numbers backwards...)
If we are talking about an APC prop those numbers are backwards should be 12.25 X 3.75 unless their making a new one again!!! You would not get those kind of rpms in Denver with out changing the comp. ratio. I would say that one's a keeper.
