Update; the engine was fine, for a 100 mile test run tuesday, even cranked it up to 120. Getting good fuel pressure now, but had a vibration about 85 up, full throttle, started pulling a little slower. Brought it back, seemed ok. Then took it for a short low speed drive.

Crap! it was doing 25, started popping out exhaust and carb, like running out of gas, pulled over, it belched so much blue oil smoke out of the hood that we thought it had blown. No oil, fired back up, and ran for 800 feet, started popping and dying again. Got it home; Fired up, good in idle, and neutral revs, then popping through the carb again, then wouldn't start again.

Checked everything again, almost acting like it jumped timing, no. Called different msd tech; get this load of bs:

"we still have the problem of tach not reading rev limiter rpm". " we disabled that". Us, "not according to the instructions, or the last tech we talked to". Wishy washy reply.

us "the red light goes out 2 seconds after key on", " that's what it does"; us, "read your own directions". Reply- directions wrong, we re-programmed the chip. About at this point, since it is on speaker-phone, the owner is trying to calm me down, before I say something.

He fix was; trigger wires too close to other wiring, I asked, how far apart? answer- 6 ". I said, ok, where the wires go into the plug of the box, how to keep the 6"? silence.

Then he asked how it was grounded. Told him, Big black to block, battery to block, redundant battery cable from block to k member, 10 gauge to firewall. Guess what? a block is not an acceptable ground.

Really more than po'ed, started moving the trigger wires, which went through a grommet in the firewall, which was good.

Now this is what we found; the violettrigger wire had someway, melted throught the outer hard sheath, and it's insulation, and saw bare wire, like it was grounding over a period of 3 months, 300 miles.

Not wear frayed, melted from the inside. Every copper strand was there, and was shiney. Replaced the wire, and runs good.

Any thoughts? Oh, to digress; we fixed the wire; popping, let it sit for 10 min, then fired like a champ. The next event, I pity the msd rep.
