2 degrees more base timing than it has now. Repeat after test drives until you get pinging (knocks). Then back it off 2 degrees.

what grade fuel, if you have 93 in the tank and advance the timing then drop in 87 you will have serious pinging and overheating problems. and what 5-7kid said will work well, if you run 93 try 8-10* base timing and advance/retard from there.
