I am trying to get the most out of my 1970 Cougar 351C 4V M code engine which has 11.4/1 Compression ratio. I have a Holley Carb I believe a 750, with a KNN Filter. And flowmaster exhaust and mufflers (no headers). That being said I have a few questions about how I need to time this thing. I am replacing the Harmonic balancer now since it has slipped so much that at idle it reads at 65 BTDC. Mallory 1256704 Max-Fire Distributor with a mallory high performance coil. Keep in mind that I do run 100 octane fuel in this engine. So I set the idle with the vacuum plugged at 6 BTDC. Now this is where I am unsure, with this distributor it is fully programmable so I can do steps or a solid curve for timing. I set mine to 22 starting at 1000 all in by 3000 rpm. Just to be safe I set the rev limiter on the coil to 6000k. It also has a option on how much vacuum advance and when to start ect that I did not touch because I am unsure what to do here. No manual seems to cover this because I guess it was just built in to the distributors? So any advice on where or what I should start the vacuum advance at and basically the total timing. I am just looking at the best overall settings to get the most out of this engine. Any help would be great thank you guys.
