GM 7-Pin HEI retrofit

[Rakort]

Anyone know how to make a later model 7-pin HEI dist work in an older vehicle? I understand that the 7-pin setup has electronic timing control (ESC?) which seems kind of attractive to me. I'm wondering if there is a control module (aftermarket even) you can hook up to the dist and program advance curves and so forth?

How about some good sites to read about this?

Thanks
