I have one of his engines, a 1950 8BA, and have heard several other of his flatheads run on stands and in cars...they're sahweeet! The first time we met we talked flatheads and hotrods for over two hours at his home shop. Walt is a great guy and knows a lot about these motors, he needs to write a book about the stuff in his head. These guys won't be around forever.
Here ya go Ken Macuch he builds some sick flatheads. and he is in westford Mass. http://www.jalopyjournal.com/forum/showthread.php?t=722137
