I think the moral of the story here is, GM stopped using points 40 years ago for a reason. It sucks. Modern ignition coils on new cars now and even back when individual cylinders started getting their own coils, is all based of the reliability and efficiency of HEI ignition.

Well, just to be the devil's advocate, a points distributor will still work after an EMP attack or a Carrington event. Can't say that for HEI. LOL

Thank you guys for all the help. Is there a HEI conversation kit you would recommend? I'm looking at HEI distributors and they range from 50-300 dollars, so I'm rather confused with what I need or should get.

I've had a $45 ebay HEI for two years now with not a single issue.  Not sure on the changeover procedure casue mine had HEI already, and especially if you need to keep the smog system. 

You should also check on your choke to be sure it is operating properly

An HEI swap will also require different plug wires. 

The original power wire to the + side of the coil "can" work for an HEI, but it is a resistor wire and should be replaced or bypassed with a non-resistance power supply wire.

the 12v on a points system should be coming off the starter solenoid to the coil

This only supplies whatever available voltage the system has during cranking. Once the key is released from the cranking position the resistance voltage is applied. A fused key on & crank B+ source to the coil is required for an HEI retrofit

HEI distributor is in, I connected the red wire from the distributor bat side to my existing yellow wire that was connected to the positive side of the original coil. I checked the wire for volts and it read 11-12. I spliced my red wire to the yellow and when I tried to start I heard a pop and everything went dead and nothing works. Checked the fuses under the dash they are all good. Dont know what's wrong now.

You cannot use the resistance wire on the HEI

You need to run a fused 12V 12 gauge wire from a Key On source at the fuse panel to the distributor. Clip the resistance wire back and tape it up good same with the wire that goes to the R terminal on the starter. Check to see if you blew a fusible link.
