Here's my opinion.
I've seen quite a few cars of guys I know from assorted Ferrari including Enzo, Assorted Porsche including Carrara GTs and GT2, Ford GTs, Vipers, Supras, assorted Lamborghini including LP640, Mercedes including SLR and SL65 AMG, Vipers, Corvettes and such stock to having assorted mods like NO2 and turbos run in street races and at the strip. There are quite a few variables, but not much will beat a good higher wheel HP Cobra on drag radials from a low speed punch through 3rd gear. At higher speeds over 100 - 115 mph the Cobra starts to show the lower HP and huge wind drag.
You really need to know wheel HP of the Cobra. A 400 wheel HP FE should pull ahead of a new stock ACR Viper from a low speed roll. Most the 550 engine HP FEs aren't making over 400 at the wheels though. Both the cars are probably good for mid to high 11s in the 1/4 on an average day with out having drag radials.
The 475 wheel HP Superformance with a small block that I recently sold would beat the ACR Viper 1st gear to half way through 4th gear(125 mph) without question.
