what is the stock timing on a 93 5.0? and how far can i got w/o detination on 93 oct.?

Re: timing *
 

I believe stock base timing for all 5.0's from 87-93 is 10 degrees advance(with spout connector removed) i used to run 13 degrees with 93 octane and no problems.

i run mine at 15 n/a with 93 and 10 with a 150 shot

Everyone's is different, you need to get a timing light and advance it till it pings, then back it down 2 degrees. if you tune it with 93 octane, then keep feeding it the 93, otherwise, it will ping. Good luck.
