Has anyone dealt with Advanced Engine Exchange?

Has anyone here bought an engine from Advanced Engine
Exchange out of Louisville KY?

I have talked to them, and can purchase a 302 or 351W short block, without having a core and including shipping, for less than the machine work and parts to do the short block on my 5 bolt 289.

Any opinions on the quality of their work? I have hopes for about 1 hp per cubic inch, so would their assembly be stout enough?
