Those are great elevations to race at! If track prep is well done, you should see your sub 12.50 timeslip. Not sure on your race experience. So just a FYI...slicks are really hard on drivetrain and torque boxes(these are located where the rear controll arms are mounted to the floors). If you have not reinforced these yet, they are a MUST DO! Also I recommend a driveshaft safety loop. With a dead hook there is a high likelihood of parts failure. Try to run enough air pressure and launch rpm to get an ever so slightly tire spin. You'll still 60ft well and not be as violent on the car. Sometimes this means more rpm vs less. It's really a trial and error experiment.
On the street our cars can't run with the new "muscle cars". Not unless you're making 350-400+rwhp(depending on the particular competition), and you have the suspension,chassis,tire combo fine tuned. At the track...you still need these same things but there can be more leeway. Most of the modern performance cars are 12.00 sec or slower(unless they are modded also) and not many are using slicks,etc on their 40k+ cars. With your setup you'll be competitive with most stock cars. At least in straight line performance. Lol

Btw, I had this odd problem at wot that yall may be able to help me with. My uncle ported my lower and he thinks it might be the issue.
Problem is, with the stock tb, it pulled great,regardless of wot or 3/4. When I put on my 65mm tb, it seemed to pull way better at 3/4 throttle than the stocker did at wot. But when I went wot, it nosed over and felt more like I let out. Make any sense to yall?
This was also with the stock cam, with the heads and such that I have but 19lb injectors
