Hey folks I went out to the local wreckers today and found an HEI distributor from an 83 GMC Van (250 ci straight six) I had taken the donor list with me so I was pretty sure I had found the right part. Donor list >>>
"Start the search for an HEI from vehicles of the years 76-82 with the GM 250. These distributors were most common in the Chevy Nova, vans and trucks. You will be looking for the HEI with the coil built into the cap. The proper HEI will already have 3 wires coming from the distributor body that plug into the coil on top of the cap. Note: It is likely that an HEI from 1976-1977 will have remote mounted coils. These units will work just as well as the others."
One of the other pages I read said that anything after 1982 would not work because GM had started to go with electronic ignitions at this time.
I hope I have the right part as I went ahead and ordered the proper gear today which cost me an arm and a leg....considering I got the distributor for $19 Cdn.
The one I found sure looks like this one >>
