What are you shifting at? 5 speed or auto?
What is you altitude at that track?
Don't burn street tires, the rubber rolls off and ***** up on the tires and make it harder to get traction....kinda like leaving on sand. When I was running my car at the track last year, I was running 13.7, then I got sticky tires and go it down to 13.5, then I messed with timing and fuel pressure and shift points between runs and got mine down to a 13.2. BTW, mine is a stock cam, stock ported heads and was a stock ported intake. I also picked up some time from going to the dyno and seeing where I made max HP, which was 4900 RPMs and I was shifting at 5500. I lowered my shift light to 4800 RPMs and I lowered my time 2 tenths consistently.
It will just take you some time, the first time you will always be disappointed.

the way you run on street tires:get into the middle of the burnout box and put your trans. in 2nd rev the motor and dump the clutch and don't let off until you hear them squeal a little and then pull up to the tree. rev the motor up around 2000-2500 rpm and when the light turns green roll off the clutch.I was runnin bald 255's 16s on my car and I ran a 13.7 @ 101 with a lot less mods than you
