Well at one point 400 hp from the Viper cost around $50,000. 450 hp used to cost $75,000, now you can get 425 hp between $35,000-40,000. Therefore, I wouldn't be a first.

Frankly, the Viper needs a different power plant. They need to make a new V10 out of the HEMI and offer VVT so then it can pass the emissions standards. This would lower the price, raise the output, and potiential. The LA based V10 is too outdated.
