Default ET gain after mods?

Hi all just curious, I am in the process of do a couple of small upgrades to my bone stock 93 LT1 automatic car. it ran 14.2@100mph in original form including original plugs. car has 69K miles. so here is what will be changed. car will be run at track in southern NJ. on November 19th with new stuff.
any guesses on gains? also stock run was in July so weather will be on my side as well.
Gear ratio:
Old=2.59
1)New 3.54
2)resonator deleted and replaced with X-Pipe
3)2800 Protorque stall converter.
4) air box modified(opened up)
5) shorty headers

let me know what you think or what yours runs with similar mods.
my Guess is car will run 13.6.

You could lose a whole second if you don't blow the tires off. Should run good.

my daughter the first time I took to track. really no wheel spin with the 2.59's and 275 street tires. I am kinda figuring next upgrade may need to be DR's lol.

I lust after a set of 3.54 gears. i have a 3.07 behind a T56. The combined ratio on yours will be a blast.
