  1. I just had barely related thought about exhaust back pressure. I've heard from some who should know better that engines run better or make more power if the exhaust system has some back pressure. Anyone ever heard that? I think I heard it in a muffler shop once as well as in a speed shop. Is there an emoticon for rolling eyes? It can often be difficult explaining the truth. I'm sure that isn't the case on this forum :-)


  2. That's the manifold heat port. The factory heads pass exhaust gas thru that port on the manifold from one side of the engine to the other to heat the manifold. That improves driveability on a cold motor by improving fuel atomization. Unless you live in cold country, I don't think you will miss it. Most folks who are after more performance prefer a cooler manifold for a potentially denser charge. The system used a thermally operated valve on one of the exhaust manifolds to create the back pressure to push the warming exhaust back thru the port. As the exhaust got warmer, the valve opened up until very little exhaust was sent back thru the port. It was common for those valves to freeze in the closed position causing a rather hot intake manifold and reduced performance from exhaust restriction. Not terribly important on a grocery getter but anathema to guys like us :-)


  3. It has been so many years since my Mustang was together I've forgotten if I had just seat belts or a belt & harness. I think I had a retractable belt with the starburst button and a harness. If I didn't, I sure would like such a setup. So far, I haven't found such a complete setup. I guess I should call one of the many vendors but I thought why not ask here. Any suggestions?


  4. Starting to wonder if the weatherstrip should be glued to the car and not the trunk lid. Someone here with a fast back that can confirm? Otherwise I'll drop the gas tank (replacing anyway) and examine/mark from inside. I have this style of weatherstrip:

  5. I'm ready to install new weatherstrip on my trunk lid. I watched the CJ Pony video but they are doing a 65 which looks a little different. On the 65, it looks kinda obvious where the new weatherstrip should go. When I looked an my 69, it didn't appear that simple. The issue is the sides. It looks like the weatherstrip needs to be offset a bit as in the picture below in order to fit the depression. Anyone have a picture of their trunk lid so I can see how it fits?
