Greetings everyone,

I am checking to see if anyone has ran across this issue. I purchased a MK2 FFR cobra about a year ago. The issue is the car runs good until it hits 3500 RPMs and when it hits 3500 it sounds like its hitting a rev limiter. The rev limiter is set at 6700. This is a 1994 302 crate engine with a 303 cam. I bought this car knowing about this issue. Since then I have changed the ignition system (plugs, wires, distributer, coil and MSD 6AL box). I recently installed a Jim Inglese 8 stack EFI. Now I am thinking it must be something internal or possibly a tune issue. The engine runs rich as well. Thanks in advance for any input.
