Greg, If I remember right, you said something about possible doing a 450, a little while back. I'm kinda anxious, myself, to see just what kind of a twist you put on one. Your 500 four isn't really my cup of tea but, gotta admire the effort and detail that you've worked out on it. When you attack a project, you really go all out and that is what really has me enthused about the possibility of a 450 or 500 twin project. As with the others, I a waitin. Keep up the great work and I'll catch you later on, Bill
