Upgrade Points Distributor to HEI
I an HEI distributor which I'd like to put in my BBC '69. Can I just do a direct swap, and land the ground and existing resister ignition wire? Will the 9.5 VDC on the resistor be enough? Thanks in advance.

Easier to install an aftermarket electronic ignition module into your stock distributor. But, if HEI is what you want, go for it.

Thanks guys. The stock points distributor is actually set up fine (Lars a few years ago) and works great. The cable for the tach drive just broke (argh!) so I thought I might move to the HEI. Running a 12V ign. wire would be a bit of a PITA so I'll stick with points for now. I appreciate the input!

You can run a feed to the distributor from the yellow wiper motor wire. Most people do that.

Sounds like what you really need is a tach cable. Converting to electronic tach is a bit of doing.

I believe you can purchase an HEI dizzy with a Corvette mechanical square tach drive in it. That should do it.

You can buy the cable and reuse the old housing if it isnt kinked or frayed, Then its just a matter of disconnecting it at the tach, sliding out he old one and sliding in the new lubed one.
As for the dizzy, you can just upgrade the on Lars set up of ryou with a breakerless system and it will still be setup the way Lars had it, just without the points. I used Lectric limiteds version and it was great until the dizzy itsself broke. I had a bushing come apart that I still need to take apart and rebuild

An HEI will not fit under the stock "small cap" ignition shielding on your 69 big block. You will have to remove all of it to make it fit. If you don't want points then just convert to something like a Pertronix3. If you don't care about the stock look or shielding then go for it but it isn't going to improve anything. The resistor wire won't work either. You have a full 12V terminal on the fuse box labeled IGN that isn't being used and that will work or go to the other (engine compartment) side of the box and replace the resistor wire with something 12ga.

Edit: Another thing I found is that the vacuum advance can had no identifying markings on it (as in dirt cheap) so when I tested it, it produced just over 20 degrees of advance at full vacuum. Not good. It looks really nice on the shelf or in the box but does not belong in a car.

Thanks guys. I just attended a car show in Seaside, OR and she ran beautifully with the stock points distributor. I think I'll keep it and just get a new tach cable.

My 69 came from Oregon and I was told they have never used road salt there. The frame and underside still looks like it just came out of the factory.
Good looking car in your sig.
