Need help - dead 56 Chevy

I`ve never had a Mallory that worked correctly. I swapped out the last one with a points dist with a Pertronix conversion. Glad you got it up and running.

 

"When it quits, the tach drops like it was disconnected even though the engine is still spinning."

That is a Pretty powerful symptom pointing to ignition.
When my turbocharged Corvair's tach wavered the slightest bit I knew it was to re-gap (and clean) the points.

 

Yes, agreed. That is what originally sent me down the path of ignition being the problem.

 

An interesting post-script to this problem. The coil died today. Now I suspect that the coil caused the Unilite to blow. In any case, I have the old GM style can coil in it now, and with the points distributor it runs great. No more electronic stuff for me, unless it is a GM HEI, which unfortunately will not fit without firewall mods.

 

See my post #5... I'm right once in a while. Gonna print this out to show my wife...
