alot faster then a CTS-V
cts-v…400hp and 4200lbs
or 03/04 terminator…390hp, 3800lbs
pully, tune and exhaust on the cobra and your looking at 450rwhp+.
ls6 cts-v you need full bolt on’s and a very very healthy cam, or in most cases a head/cam package to make that power, then its still 400+lbs heavier.
