Be Honest those C6 Z06's are monsters.... Dyno around 440-470 RWHP, And a 2003-04 SVT Mustang Cobra has to have around 550 RWHP Just to hang with it, Needs more to run away from a stock C6 Z06 Vette. I also know that a SVT Cobra is Bad enough... Im a member SVT Performance, S/n horseplay lol. I give lots of respect to these... I seen only one by my house and it was yellow. I see tons of regular C6's and acouple New GT500's. Depends on what kind of trans am... New or old? LS1 Can easily be fast with bolt ons and with H/C/I They are way fast.
