Photo-blog dedicated to the things we dream about... muscle cars. Most of the photos found on my blog are found on the internet. If I can give credit I will. If you wish to have a photo removed, please message me and I will remove them.
Truthinperception, I think that Ford currently offers the best performance/bang for the buck by way of the Mustang. It holds true to it’s heritage and has a classic design. The biggest thing for me is that you can throw it around much easier than the new Challenger and Camaro due to lighter weight and smaller wheelbase.
The biggest thing about the Roush Mustang is that it is designed buy the owner of a Nascar team who has extensive knowledge of suspension, breaking and overall handling. The upgrades found on the Roush make it a killer on the street.
On the other hand, the Shelby keeps much more of the stock Mustang suspension components but makes about 50 more hp, so traffic light to traffic light or at the strip it will be your winner.
Overall, I think any car lover would kill to own either vehicle. If I could choose, I would take the Roush. If you need more hp, it is easy enough to change the supercharger pulley (and maybe add meth injection to keep detonation down).
