This is definitely a great example of how many performance issues are blamed on the carburetor when its actually an ignition issue. Fellers, check your timing!
One thing to watch out for when switching to HEI is voltage. Those 2 wires that come from the solenoid and ignition switch may not carry the full 12 volts that the HEI wants. The one coming from the solenoid will have 12V, but the one coming from the switch might only have 6 to 8V. Especially if you're converting from mechanial points. The external coil from those systems can't handle full 12V,so they're ballasted, or run throu a resistance wire to supply lower voltage. Make sure to test each wire to insure that you're getting full voltage in the run position as well as the start position
Excellent video! I am having the same issues and have tried the same things to no avail. I’ll try the distributors. Do you have a link to the specific distributors you chose? I have the same breakerless ignition system you had before the upgrade. Thank you
Unfortunately I don't have a link but I ordered the distributors via Summit racing. They were very knowledgeable and I talked to DUI prior to finalizing my order to ensure I had the correct distributor. You will need the pigtail and new 8mm plug wires(I had to order 2 kits of SP wires to get enough long SP wires to reach the plugs). Any questions reach out to me. Easy install! Make sure you use a vacuum gauge on set up!!
