I got my old books out. They have hand drawn diagrams by Tom Hoover in 1975. I can't scan them. To get then to scan I have to break the bindings. They are already getting pretty frail. These books are from the 70's. My camera does not have a flash. I'll try to borrow one that does and go from there. The books have everything they used to use including carb jetting. The main book is from 1976. They were called bulletins. Later, I believe in 1980, Larry Sheppard compiled them into the Direct Connection Performance Book, or as many called it, The Mopar Bible. My Dad does a lot with the Chrysler 300's. He knows the guy that had FAST do a long crossram set up in the '63. They have a puddling problem also. Then they will backfire and burn the paint between the hood and the fender. I used to think it was cool to see two fireballs as a kid in my Dad's 300. Now I know why he was so distraught when it happened. Neil is right. Injection is the way to go. I plan to check on it with FAST.
