I'm not trying to keep old parts, I was just trying out if cleaning helped anything. The cap looks like new, does it still means it might be bad?
Just found out only 3 cylinders work in my 1970...
... no wonder I wasn't impressed with its power.
It's a 472ci, all cylinders have about 9.5:1 compression.
Took out a timing light and it flashed on only 3 wires.
I took distributor apart, cleaned corroded breaker points, adjusted a screw, but it still fires on only 3 of them.
What could it be? A capacitor, wires, what else?

Tested the wires, almost all are bad.
When I changed the oil few weeks ago, it looked like it was 50% fuel and 50% oil. Previous owner said the carburetor floats were stuck, but I guess now I know that they're OK.
So what's about the HEI that everyone talks about? Everyone says it's much better? How? Would it increase the HP and/or MPG? What exactly would I notice when I change to it?
Do I have to buy HEI only from newer Cadillac or are there other cars that have HEI distributor compatible with 1970 472?

Update.
Put new premium ACDelco wires and now it runs worse, won't ever keep idling if I don't hold the throttle pedal, probably because I was adjusting points without knowing how to.
Going to do electronic conversion soon.

I bought new set of points (the most expensive ones) and a set of premium wires, spent 2 days trying to get them to work, checked everything, replaced spark plugs few times, then I put old points back in and it started right up, adjusted them and now it runs like a dream.Why are you trying to keep those old worn out parts? That ignition stuff has to be in near new condition to work as good as they work (not so good). Cleaning burned or carboned points never works. Cracked dist caps were fairly common in the old days. You can't even see the crack unless you have super human vision. Give it a real tune up and it should run like it was supposed to. Good luck and enjoy that nice '70.
No I went by the gap size, tried every gap size possible.Are you using a dwell meter to accurately set the points?
I bought automotive multimeter (should be here in few days) so then i'll be able to measure dwell.
