Re: hei distributor

run a 12 volt wire(dont remember what gauge) from the ign. male plug at the fuse box to the hei and a wire to a tach (if you have one) from the hei cap. been doin it that way for 20 yrs now no problems yet! make sure you get an early style hei unit (non computer assisted)!

Re: hei distributor

Jerry, one of the great things here at TC is the amount of info available with a search. If you search "HEI fit" you'll see 7 pages fo threads, and more than one of them discuss whether a big cap GM HEI will fit a 1st gen, and which motor mount/frame stand combos seem to provide more clearance than others. Then you figure out what style you have, maybe take a measurement from the center of your existing distributor to the firewall as a double check, and kinda go from there.

As far as power supply, the cleanest way is to remove the existing cloth-covered resistance wire from the engine harness connector and replace it with a 12 gage wire to the "BAT" terminal in the GM HEI; if you just use the resistance wire from the points dist, it won't give a full 12V to the HEI. You can also properly tape up/abandon the yellow wire from the starter to the coil; this was a full 12V supply to the coil/dist only when the key is in "start" and the starter is engaged. Because the HEI will get 12V from the new feed wire you install, you don't need the yellow any more.

Re: hei distributor

Replacing the wire only pertains to HEI only correct? I'm getting ready to switch to a new Mallory/Summit electronic (old points style) and want to make sure the original wire is okay.
