93 5.0L Timming

no you won't but it depends on the gas you use.

you want to run the timing as high as you can w/ out detonation.

if it's not pinging at 14* leave it.

if you wanna "power time" it , go to the track and make comparable runs (cooled off, everything the same)

increase each run by 2* and then put it where your mph was best.
