Ok, i my timming and it was at 10btc, and reved the engine up to around 2500. The timming advanced to 25btc for total. This is in a stock 351w. I also hooked up a vacum gauge and was running about 15 inches of vac. So i advanced the timing to about 23btc. The vac came up to around 20inches. I thought this was to much intial timming and set it back to around 14btc, and took for a drive it seemed to have more power and did not ping at all. The question i have is what should my total timing be for a street car and would i hurt running at 14 or putting up to 25 again for intial. I am running a mallory mechiancal advance dist. as well. Any thoughts?

You should have a total of around 32 degrees, all in by 2200-2400 or so. If it start fine at 14 degrees, leave it there, then just adjust your advance weights to provide the other 18.

The rule of thumb is the most timing you can get away with without pinging, the better.

They're adjustable. Remember to double the numbers stamps on the dist. {i.e. 6 will yield 12 degrees, 8 will yield 16, etc...}
