C6 Corvette, 400 hp x 1st gear ratio (6MT) 2.66 x final drive (std) = 2904 ft lb
M3 M-DCT 295 ft lb x 4.78 x 3.15 = 4447 ft lb.

Now this is just one gear and peak values, but should get the point across. The M3 makes way more peak wheel torque in 1st gear than the C6 Vette.
C6/base/LS3 numbers:
428 ft lb * 2.66 (1st) * 3.42 (final) = 3893 ft lb

C6/Z51/LS3 numbers:
428 ft lb * 2.97 (1st) * 3.42 (final) = 4347 ft lb

So M3 is a little higher in 1st, not way higher.
