John, Don't let this FE Stuff get you down. We're all like practicing Doctors and Lawers. We're just practing FE's. Cobra's are a on going project. Everyone has there two cents worth of advice. Listen to everyone and learn. Just drive your Fe and have fun with it. If you don't run it at high RPM's for to long periods of time. It will probably run fine for a long time. I have had friends even with 427's with low
oil pressure and they just lived with it until they wanted to rebuild and upgrade the whole engine. Like one guy said, there just rough tough truck motors. They are work horses. If you not pushing much over 400HP they are pretty tough. Good luck and enjoy! Ken
