Cruise Prop/ Power Setting Question

My recently aquired 7ECA came with a cruise prop installed. How do the power settings in the manual which are based on the standard prop relate to what I would use for the cruise prop? In other words, at 2500' my manual says that 2600 rpm is 76%. What would it be with a -54 prop vs the -52?

Thanks!

I have a 1976 7ECA with the 0235-C1 and had the 46 pitch re-pitched to 50 and found terrible fuel burn not to mention lack of climb power. I re-pitched it to 48 and it seems to be a good all around pitch. Fuel burn is around 7. I AM looking for more RPM on takeoff and need a 46 pitch to get it. My prop cannot be re-pitched anymore. If there is anyone with a 7246 prop I'd be interested.
