Distributor didn't change symptoms.

Ran the valves according to Comp's EOIC method but used 3/4 turn pre-load vs 1 turn. #8 exhaust was loose at 1/4-1/3 turn of pre-load from zero lash, the others were pretty close......though I'm getting doubtful of my competence at this point.

Once the radiator shroud and fan are back on we'll fire it and see what happens.

The high idle can also be chased to a vacuum leak.... Have you checked for that? All the ports on the carb plugged -- PCV working correctly? Intake sealed?

Okay -- and I see another possible issue.... ASSUMING you're running an MSD box... since I see you've put on a GM weatherpak connector on the distributor.

The Black/Violet wire is negative (-) while the Black/Orange is postive (+). The wires that come out of the MSD are Violet(+) and Green (-). The 2-Pin connectors are designed to only connect one way so the wiring cannot be switched. If for some reason the connectors are changed, be sure the wires are connected with matching polarity. If they are not, the engine may or may not start, but if it does the timing will be inconsistent and it will run rough and not accelerate.

I know I'm digging at the little things -- but at this point nothing can be taken for granted.

Taken after I ran the valves. Check

Had the carb off, could be a base plate leak. No ports on the HP Ultra, PCV is new, intake freshly installed Edelbrock gaskets. Will double check all points. The idle does hang, could that cause the timing fluctuation?

No box, that's the MSD dist. wire connector.

After just firing it and having the same symptoms me too!!

Vacuum leak makes sense. Electrical short in tach, ignition wiring?

I guess the plus is it's not the valve train..........I think.

Let him win, if he starts loosing and leaves this place wouldn't be nearly as much fun.

Hawk's? Are they similar to a Sea Buzzard?

I'm almost frustrated...............almost. Proof is in the fact that I haven't thrown anything across the shop yet.

We all want the AH HA moment and then everything is right with the world....

I've always USUALLY found that it's something SUPER SIMPLE that only makes sense after it's accidentally discovered. In the mean time --- SO F'N FRUSTRATING!
