Mark I have a 72 inch prop on my 360. If you put a spacer between the strut
and fork it helps your clearance.( ask Vern @ lancair he can get you one.)I
had a 70 Inch on,this was before Lancair had Hartzel check their 360 for
harmonics,come to find out it was a bad match.I talked with Hartzell and
was told the 72 inch would be o.k.The 68 inch prop
designed for the 360 is a result of this study'
My preformance is a few knots slower in cruise,but 3to400fpm better in
climb which helps me because I fly out of 5000ft elevation airport.Hope
this helps.
