I neglected to mention I've got a Mallory Voltmaster II coil mounted to the block (instead of the stock coil). This unit requires a Mallory p/n 700 ceramic resistor in series with the yellow lead from the solenoid to the coil (+) positive terminal. The old one was flaking apart in the back after only 25-odd years and, although continuity rang good, I was unsure of nominal resistance values, so I decided to R&R it.
Meanwhile I noticed the vac adv can was bashed and wouldn't actuate, so I replaced it. Still no power at speed.
Thinking maybe the harmonic balancer had "walked" or spun so timing marks were off considerably -- I pulled the dampener. It looked OK as far as the timing mark being within 4 or 5 degrees of the timing mark on a known good '67 balancer with the woodruff keys lined up [one on top of the other]. I went down to the car wash and blasted an unknown amout of "gak" off the part. Cleaned up -- I saw the inertia ring was not flush with the front of the mounting center but pushed aft maybe 1/4". I'm going to show it to some machinists later.
The big bite is the timing gear cover has a rip in it from the crank gear inside and the harmonic balancer in front - with road dirt -attracted -abrasives building up on the back of the inertia ring - it wore a 3" by 1/2" tear in the sheet metal for oil from the timing gear oil director to leak out from. I think I found my high speed oil loss. The saved donor timing cover from the '67 block had the identical rip! Today I'm on a sheet metal hunt at the junkers.
