What part number on your distributor tag? Starting in 68 cars where Emission cars with CAP. So besides leaning out carb, the distributor specs changed. Do you know what Letters are on the Cam stop plate?
For 70 normally looking at 13-15deg distributor advance. So that puts in 26-30 at balancer. Depending on Standard or Auto transmission. Timing was set between 0 degree to about 2.5 BTDC.
If distributor is worn, or sloppy, you will have even more advance. So what is your initial set at 8?
What is your carb jetting, is it stock CAP lean, or jetted richer?
