The engine pulls hard to 5700 and then it quits pulling and the tach will not go above 6000 no matter how long you hold it. It has a solid cam, and the valve springs are correctly installed. I was there for every step of the heads. In fact the first springs I got did not match the specs so we orderd a second set to make it right. I have been playing with carb float levels and ignition timing and maybe helped a few hundred rpm. It has autolite 32 plugs. I went with a colder plug for the higher compression. The plug readings have been good. The look a little funny when you burn 114 octane! I think your right in it being a tuninig issue. I'm just ready to here this old FE sing! Thanks Kevin |
