Last years AirVenture deal from Superior was $500 off plus free shipping in addition to their new lower prices for 2006.
Had to take delivery by 12/31/06 (which I did).
I took the plunge and bought an XP IO-360 (Airmotive Performance), roller lifters, constant speed ready for $20,900.00 (3 yr warranty).
Couldn't pass it up. Unfortunately I haven't hung the engine yet, but the box looks real nice in the middle of the shop....................
I imagine the same deal might be available this year.
