I've been working on this for a while and finally think I have it figured out. I bent up some different throttle brackets to fit my 470 engine now that I have fuel rails on it. After trying a couple of different designs I decided to go with a Z shape and made it out of stainless. Here are a couple of pictures. Once I get a few on hand I'll ad them to the website and they'll be available from Mancini or Hughes.
