Stick or Auto?

But remember, the L99 also has VVT where the L76 does not. In my opinion, variable valve timing makes the 6.2 auto combo a tuner's dream come true...especially with a big cam. Advance that sucker to boost your torque down low, then retard it to extend your rpm up high. A six speed LS3 combo won't give you this.

With VVT and a high stall converter, the A6 has tons more potential to be faster. Just think about it...variable valve timing...high stall converter...tight gear spacing...it's a dream combo. In the hands of a skilled tuner, a properly cammed L99 can make tons more low and mid-range torque with the VVT advancing the cam down low, then extend the top-end by retarding the cam up high.
Ditch the AFM if you want, but the variable valve timing is a godsend.
And only the A6 combo has it.

This.
(1st: 4.027, 2nd: 2.364, 3rd: 1.532, 4th: 1.152) mix with the 3.27 rears and its good bye M6. No no, not just from a dig but from a roll too. That 6L80E isnt going to let that 40 roll BS fly anymore.
I cant wait for some L99 cars to stab a converter and de-torque manage. I so wish I had that damn 6L80E in my car.

It all boils down to.. which one would you enjoy driving more? It sounds as though your not really planning to build a purpose built race car. So buy the car that you will have the most fun with.

I have decided and am going with the auto. Stock I think I would have had more fun and enjoyed the stick but i plan to take this car pretty far. I am getting Kooks headers, corsa exhaust, vararam induction (if its finally out), and a custom dyno tune right after I break the car in. A year or 2 after I will get a torque converter and matching cam and then who knows. I already ordered my 1SS RS Black on Black a couple days ago. Thanks everyone for their input. This will be my first brand new GM muscle car and im pretty excited. I dont even mind wainting 2 months as that will be enough time to save up for my first round of mods. I think with the correct combination of parts and tuning these l99 cars are going to be wicked sick. thanks again everyone.
