BunkerHill -

Check out the RCU Classifieds "Gas Engines for sale". I believe I saw a couple of Quadra's listed at reasonable prices. You might also look up and contact William J. Krummel, Jr., you can do a search for him in RCU. He uses hopped up US41's on some big warbirds and swears by them! A real nice gentleman and very helpful.
