ERA runs them down both sides of the engine to reduce feedback. So, before you pull the engine go ahead and separate them -- what have you got to lose? You've checked and disassembled your carb, checked the linkage, checked the timing and advance, checked the valve lash, checked the integrity of the fuel, checked the spark... and your car stil won't rev much over three grand.

There's still a possibility of exhaust obstruction, a bad MSD box, or something else that I can't even guess at. One last cheap test is to go out and buy a pyrometer and shoot it at your exhaust headers and see if there is a noticable temperature difference on them. Then, before I pulled the engine, I would put a new MSD box in and a new carb on. You do have the positive and negative feeds to the MSD box coming directly off the battery, right? Not the little "ignition on" feed, but the red and black power feeds. That's really important.
