Tony,
On the last qualifying session at the Runoffs, I had an issue that cropped up where the motor would act like it hit the rev limiter too early, even though I was 500 rpm or so below the rev limiter. It ran fine all week prior to that.
Out of desperation (the race was the next day) we replaced the cap, rotor, plugs, and plug wires and it cured the problem. We think the ECU was picking up stray noise from one or more of the above components (most likely the plug wires) which was getting interpretted as higher revs. Something to consider. FWIW, I put in cheap suppression-style plug wires (all that was available from Pep-Boys near Mid-Ohio) and they worked fine. In fact, I'm running them on the new motor with the new OBD1 distributor set up my prod car.
Also check your ground wires. I had a weird problem at the first national at Gateway which acted like fuel pick-up (only happened in left hand corners) but turned out to be the ground wire near the T-stat (the one I showed you this weekend) being finger tight and cutting out when the motor would rock under torque in left hand corners.
The ignitors do go bad on these cars, especially if they are old.
