A three blade prop doesn't require more gap from the requires a deeper slot (cut further forward) for the nose gear so that the cowl can be lowered down much further to clear the prop blades. I had probably the first RV "A" model with a 3 blade prop back in 1993. I just made an aluminum cover to screw over the slot in the cowl bottom.

BTW a 1/8" gap works fine (in fact an even 1/16" works with no rubbing on most installations) but the closer the gap, the higher the difficulty of removing and installing the cowl. Especially if there is an improper interface between the FAB and the induction air inlet.
