250kt cruise is really pushing it in a piston engined airplane. A 421
can max out at 250kts, but cruise will be more like 220-230kt. The
only exception might be a Lancair IV-P and this was posted to the
homebuilt newsgroup, so that's a thought.

Will have a look.
Aerostar does 250kt OK at 25000. TIO 540's.
Range is limited by 38-42GPH and gross - empty = 2000 lb.

Looking for single that can do the 250kt and max gross - empty = big
enough number for fuel plus 250lb.
