This is my first post. I have been building an A&C for a few months now. I used the 22 1/2 measurement and the headers didn't line up where they were supposed to. I am using s 351c. Dimensionally, the headers should wind up in the same place as a 302 or 351w. I found I needed to move the engine back 2" for the headers to exit properly. You need to set the body before you mount the engine. I have my body hanging from the ceiling so it's easy to take off and put back on again.
