I have a 71 that I have dropped a 280 motor into. It runs so quite. It has the orginal double muffler set-up. I was going to take it down and have the exhaust changed to 2.5" and a single generic muffler. I got to looking at the orginal manifold that would still be there, looks small to me. Does a header give much more power? Where is the cheapest place to order z parts? I tried to buy a gas cap yesterday for the 71, it was 37+tax seems a little steep to me. thank you for the infor.
