RE: 428 Shelby Engine "pings"

First off get rid of the octane booster as it just does not work as advertised (even the so called best)your engine is approx 10.8 to 1 so if you are running in a warm climate you simply need better gas for starters. Initial timing of 16 to 20 is quite common for your engine/car just using mechanical advance. Where is the vacuum line hooked up to on your dist? if you have 10-12 initial with mechanical & vacuum you are probably getting 50+ combined which is way to much. These engines like around 35to 40 total depending on a lot of other factors. Get a advanced degree timing light avail at sears for approx 49.00 then check total advance at approx 2500rpm (or increase engine speed until it quits advancing (thats with the vacuum advance hooked up. Then do the same with vacuum advance disconnected. from there you can figure your initial,mechanical advance and your vacuum advance. All ford distributors have an adjustable mechanical advance by taking off small snapring (under rotor & felt if there)also taking off the breaker plate. this will expose the mechanical side of dist. the advance figures will be stamped on top, just see what is being used then to change it simply lift it up after taking springs off then rotating it 180deg. Most of the time with a 18-20 initial and adding mechanical its enough for the engine just do not use the vacuum part of it.
This thread, so far...
