I have an HEI distributor in my '69. But my question is about ignition condensers. I'm trying to find values (in microfarads) that are used. Does anybody know a website that shows these values? I have a friend who builds ignitions for real old non-automotive engines. Thanks.

I think most will test out to be between .24 and .35 mf "Most" oldtimers say that more is better. FYI, Mopar 318s are closer to the .35

Gary, Did you run a large (#10) +12 Volt wire from the ignition to power the HEI? HEIs need more current than the stock ones.

Once upon a time, dinosaurs roamed the earth, and you were supposed to actually LOOK at the old points that came out of the distributor at tune-up time.

There will be metal transfer from one contact to the other. One contact gets eroded, while the stuff that erodes off will stick to the other contact.

Depending on which contact got eroded, you changed the value of the condenser higher or lower. Problem is, I don't remember the "rules" for deciding which way to go.

Dave, thanks for the info.
