What’s the ignition timing on a 351 Windsor?
This engine really likes octane and timing. I have to run a mixture of 110 octane race gas and premium pump fuel, the intital timing is set at 6 degrees and when I hook the vac advance line back up it goes up to about 26. When I rev it up it appears to go as high as 55 but it runs awesome, great power and throttle response.
How to check ignition timing on Ford 351 Cleveland?
Ford 351 Cleveland Engine Ignition Guide: Timing. Under hard acceleration or loaded on a dyno, listen for spark knock. If you have spark knock, retard ignition timing 1 degree at a time and try again.

Do you need a vacuum advance canister on a 351W?
Personally i do not think you need the vacuum advance canister. I have my 351w set up to 18 degrees initial and my MSD dizzy has 20 degree advance mechanical in it. So i run 38 degrees. I am thinking of getting there other bushing i believe it is for 25 degrees mechanical timing and then i can bump my initial down so it fires better in the cold.

The vacuum advance is operated off throttled vacuum advancing the spark when you step on the gas. As revs increase, vacuum advance smoothly hands off to the centrifugal advance, though both work continuously.
What should ignition timing be with vacuum advance connected?
Total ignition timing with vacuum advance connected should be no more than 36 degrees BTDC. At idle, it should be 6 to 12 degrees BTDC. By 1973, distributor vacuum control became more complicated, with some applications having an advance/retard unit and some having only an advance unit.
