Nice WOT numbers there Mark. I'm about 25 rpm less than that but I'm a few tenths of an inch more pitch than you.View attachment 77963
Based on what others have said, I was lucky I guess that my old tachs and sync gauge were fairly accurate. I do not have a synchronizer either so I was never really sure until I put in the Aetnas, but the sync gauge is right on at the lower rpms and off just a tiny bit at wot. Not enough to bother to adjust imo.
Hopefully you’ll be lucky and not have to adjust it also.
