My typical late $.02 an auto with the proper convertor for the cars power band will ALWAYS be quicker (lower et) becasue of the very nature of a torque convertor and how it multiplys torque goin to the tranny....That being said assuming you run to 10.50's the stick wil be faster (more MPH) because it take less HP to run. A good example is my street car runs 13.3's with the ocasional 13.2 and the best MPH i have ever had is 100.15 and i have only MPHed 100 one other time typically i am in the high 99's but How many stick cars on slicks without TDD (traction deficit disorder) run that quick with that low of a MPH. Where it sucks though is on the street from a roll i am running with the high 13 stick cars. which is a whole different class of cars while i can take out LS1's at the track from a 30 MPH role on the street the take me. My answer to your question would be no your car won't be faster but it would be quicker with the auto.

To add one more thing (in reply to ultraflow who i agree with) one more thing i would do is dyno your car with the t-5 in and send that info to a convertor manufacturer and you should get a spot on converrtor for your car.
