I have exhaust manis on my 350 right now.

The 350 manifold didn't fit the body since the exit was right on top of the motor mount, the 307 manifolds exited behind the engine cross member.

A "14" and a "17" will work, these were made from 81 to mid way thru 85. As long as they are completely open in the middle port, they will work.

14 is the left side and the casting number is 22503678

17 is the right side and the casting number is 2506300

This is what I have, until I get my headers
