I have been thinking about this setup for my next project. I would be installing it into a Demon. I have figured out that it can be done with some modifications to the rad support area and the firewall. There is another cost that is going to have to be figured in and that is headers, they will have to be custom made. The only other alternative that I see to that is to go with an Alter-K front suspension, which you may want to do anyway. I don't think this is about horsepower, although you will get lots of it from an SRT-10 engine. Another area of concern is the trans tunnel. It will have to be reworked as the Viper tranny is higher than what the current tunnel can accept. There will be other issues that will require some fabbing I am sure. This would be a real cool street rod!!!
