This is what it says inside the hub (when first delivered):
68x74 26.1(degrees)

The last is probably a number Clark has in his records and so he could give you more specifics.
He changed it somewhat when I sent it back from finishing. I think mostly he made the tips smaller.

Hey Finn,

 

I can't believe I didn't think earlier to ask about your prop.  What brand, diameter, and pitch are you running?  My Warp was 68" diameter, but I'll probably give Performance Props the option of using up to 72" if they think that will be better.  Sure wish I could figure a way to get that -C drive installed without having to re-work the whole front end again. 

 

Cheers,

Rusty
