Ahh here we go, this should add to the fun:

2006 M6 dyno, around 300 ft lbs to the tires from 4-8k, would really like to see the numbers below this, but oh well, hey all this from only 12:1 compression, variable timing, etc..

Stock 2007 Z06, over 350 ft lbs at 2300 rpm, at 3500 we're over 400 ft lbs, 450 ft lbs to the tires at 5k, still over 400 to the tires at 6300, and finally backing down at 6750 down to 350 ft lbs again.

So over the whole usable rpm range for each engine (dont try to turn this into a put the same gears in both cars game ep, we know your gearing should match the rest of the drivetrain), we've got the weak, 500 HP corvette engine only besting the M6's 317 Ft lbs by 132 ft lbs at its peak, and no matter what in its 2300-6300 band by generally 100 ft lbs....


You can have the M6 engine and some 4.10's, i'll take my inefficient, cant flow much air sbc and 3.54s
