GM 8 pin HEI Conversion pics

I installed the 8 pin module on my 440 dart and couldnt get rid of the pinging..turns out the 8 pin adds 10 degrees of advance right off idle.I watched it with my timing light at idle, then as soon as i slighty raised the rpm's, it jumped 10 degrees every time. I switched to the 4 pin and stopped that issue, so beware of this!
