I'm glad someone else picked up on that.

I tried one of those electronic gizmos (don't remember who made it) in the distributor that you replace the points with an HEI module. The car would run, but it was very hard to start, almost as if the starter motor was taking away too much juice from the ignition for it to work properly.
It was disappointing because I used one of those same modules to replace the points in my old "Farmall A" tractor and it worked so great I thought it would work well in the 'vette. I should have spent the 100 or so dollars toward a HEI tach drive distributor.

elec distributer
I have been looking at the elec dist with cable tach drive and found this info just what I was looking for. However, when I click to e-bay, the vendor site or ? has been dropped.
Does anyone have an update on the source and brand?
From the previous notes, the distributor is of excellant quality and the price is right.
Thanks for the help,
gm

HEI is much larger dia than points cap. HEI really don't fit points chrome box-lid... but you can beat on it & force it ... results can vary.
Instead, look at chrome top shield-lid & brackets for 75 thru 77 (they have OE HEI) ... many of the vette vendors offer them.
Your radio/stereo does not require ignition shielding if you run spiral core plug wires; though aesthetics may demand it.

tach drive distributor
nelson specialties 7046626600 has numerous OEM units in stock. Many of the aftermarket HEI units (Chinese) have an undersized housing causing low oil pressure
