You have a cam, cold air off road H pipe and 3.73's...
You would be lucky to be making 250 at the flywheel, unless you forgot to mention heads/intakes/headers/tb/mam etc...
Stock convertor will not want to give you much more than a 1.9 60', and the mod's you listed should put you handy to 100mph in the quater... that should be good for high 13's... but I'm gonna guess 14.2's... that should be 9.1's in the 1/8th.
