Hey guys I just put a 600 cfm Holley carb on my car. Initially I plugged the distributor vacuum advance to a full vacuum carb port. Great results. Should I have plugged the vacuum advance into the timed vacuum port or, does it matter.
You got it right, full vacuum at idle/sustained rpm, low/building vacuum under acceleration controls your timing as it is needed. Make sure to set your base timing with the vacuum advance disconnected and plugged.
