Hey, Ray!
Nice Web site!
Its kinda strange that you are just starting the banger "curve", and after several years of fooling with them, (and early V-8 Fords), I just boght a hotted up '36 stovebolt!
Go HERE, first, connect to ALL the links for some really good ideas. This will give you at least a start into the whacky world of bangers! Subscribe to their newsletter, it is excellent.
http://www.hotforhotfours.com/ Then, spend a little time here:
http://www.fordbarn.com/ Here are MANY good links with lots of information, particularly in the Model A links. Also, you already mentioned Charlie Yapp's site, (Secrets of Speed), which is another good place to find out what's going on. Their bi-monthly magazine is LOADED with good stuff.
I have a fair "handle" of some of the information you may be interested in. I know what I know, and I also know what I don't know, and ain't afraid to say, "I don't know"!
If there is ANYTHING I can do to help, just let me know. BTW, I just talked to a guy here in Wilmington today that has a Model A motor for sale, and, I think he said, 4 or 5, '32 up, "B" Model motors for sale, (which is the "one" most all the hot rod guys look for).
Anyway, good luck, HAVE FUN!!
