![]() I just got the new motor in my 86 mustang running. Its a 302 bored .030 over with flat top pistons. Edelbrock performer RPM heads and edelbrock performer 289 intake with a 670cfm street avenger. I'm running a street anhilator ignition system. My problem is that right around 3000RPM it starts missing severely. It will go past 3000 but it really doesn't like it. THe rev limiters are set to 6000 so its not them. I just installed a new set of 3926 autolite plugs recomended by edelbrock and new wires, cap, and rotor. Does anyone have any ideas what could be wrong with this thing? It runs awesome up till 3000. Awesome throttle resopnse and everything but just has a severe miss in several of the cylinders. The compression is between 140-150 with the motor ice cold. Everything checks out as being right on the motor. I've gone as far as to switch ignition boxes and coils and still have the same problem.
