What is the BEST 1/4 Time for a STOCK 1991 GT

[Superpromustang]

My 88 GT went 14.66@95 bone stock, then with timing adjustment 3.55's and MT 26 X 8.5's it went 13.87@101 with a 1.878 60 ft, but then again the speed density cars always seem to run better than the mass air cars. I once read in an article of MM&FF April 97 issue I think, the mass air cars run a fatter fuel mixture of about 13.3:1, where as a speed density car runs leaner of about 14.0:1, so if you can get a bone stock mass air car to run in the 14's that's awesome
