Run the wire by itself
I had a similar problem with my 392 running to only 4000rpm. I looked to this web site for help and got it. My MSD 6AL is installed inside the engine compartment, passenger side, just forward of the radiator fill tank. The root cause of the engine missing, at 4000 rpm, was due to the tachometer wire being run, along with all the other wires, through the firewalls single opening supplied for that purpose.
One of the guys (just like kitcarbb) explained about the electrical interferance and how it can and does interfere with the tachometer working correctly. So, I followed the guys advice and ran the tachometer wire away from all the other wires and had it enter into the drivers side through the steering column and up into the tach. Problem was immediately solved.
I have had clutch problems too and by reading and applying the information provided from the members of this site, I was able to resolve that problem as well. If its not already fixed from all the good info provided then give this a try.
Good luck from Austin Tx. and to all you cobra club members.
