I actually own a 2000 C5 Corvette hardtop with 6-speed manual...I often wonder which one is faster...My corvette is stock as is my SRT-6 vert. Magazine times for both in the 1/4 mile is 13.3 seconds at around 107-108 mph. 0-60 for Vette listed at 4.7 seconds vs. 4.8-4.9 for SRT6.

Overall the Vette feels a bit faster in the seat of the pants category. Hard to compare acceleration in manual car vs. a smooth automatic.

If the Vette is putting out the advertised 345 hp/350 lbs torque and weighs 3,180 pounds vs. 3,320 lbs for my SRT6 vert with auto and less torque, the Vette should be quicker. However in the real world, it would depend on the launch of the 6-speed manual vette...too much wheel spin in the vette and the SRT6 is going to zip in front! The SRT6 is definitely easier to launch.
