Ok so here is the deal. My 1969 has an early model 302 (3 bolt balancer). It runs great and starts fine. So I am adding A/C to the car and the dist. vacuum advance is in the way. Number 1 plug wire is in the right location on the cap but when I checked the timing this thing is about 40 deg ATD center? It has been to long since I messed with early model dist I can't for the life of me figure what is wrong. This motor was rebuilt and when I purchased the car the PO informed me the dist was installed that way. I know the only way to correctly verify the timing chain was installed properly is to take it apart but that is not going to happen. Does anyone see an issue with just removing the vacuum advance until I sort this out.
