From Jeff and Dan's posts the 10 gal fuel burn ain't all that bad with the 140 mph cruise. Thanks for the info.

Weeeelllll, I will qualify my post by saying that I never saw 140 mph in my 150/150. Wayne's and Dan's are faster as at 2350 rpm, I usually planned for 120 mph.... It could have used a different prop too as best rpm I ever saw was 2550. Now the 180/150 may "cruise" at 140, that's about what I see in my Cardinal (135-145 depending on power settings TAS).
