Spec - rebuilt 57 type distributor (NAPA), single points, Edelbrock carb and B intake. Rump rump cam but not sure of specs. 312 .030 over. Top loader 4 speed. After a change in carb and intake, I noticed it was pinging (previously ran 3x2 with no vacuum to the distributor) so I checked timing. Took the vacuum line off the distributor (plugged). put on the timing light. Initial around 10-12 degrees. Put the vacuum line back on and checked for total. It went to about 50 degrees (tape on damper). Did not know rpm at that point. I thought total should be about 35 or so. Is this correct? Should the distributor be recurved to limit advance?



I guy told me that if there is no load, advance will be higher than if a load. Is this correct?



Thanks for any help
