Need Distributer Guidance - The 1947 - Present Chevrolet & GMC Truck Message Board Network

69 air cab · 01-25-2004, 04:24 PM

I have a 69 C10 with a 350 that I found out has an MSD setup.
I'm trying to stay original with except for a few upgrades.

Questions>>>>>>>
If I go with say a 76 or later HEI Distributor so I won't have to deal with points, does anything else have to be changed?
Will it affect the wiring harness in any other way?
Will anything else have to be changed out?
What are most of you guys doing.....staying with points or other?

most are going to stock hei ....74 and later.....if considering a upgrade....
the only change is the resistor wire powering the dizzy need's changed from the resistor wire to a reg. wire to get full 12 volts
feeding the dizzy

You will need to replace the resistor wire with a wire that will supply a full 12 volts.

Hmmm, I never did do this when I switched mine over. I guess I have a little project to do!

and am sure you will need to have the HEI unit 'recurved" for the proper centrifugal advance for the engine that the HEI is installed. There is considerable difference in the advance in later HEI units as compared to the 69-72 series trucks
