While totally different, there wasn't that much design change related to aerodynamics in those years. I'd bet the CdA is only slightly different between the two cars in stock form.
I'd say the Blowfish vs SuperCuda is a fairly good comparison of how aerodynamics affects speed on similar cars with similar power...
Of course, it's also worth noting that the SuperCuda has been modified aerodynamically as well. It's been lowered and has a belly pan, splitter, and rear diffuser.
