I was disappointed when Gen2 Garage shifted to a Dakota. I was excited to see someone try and make it work in an A-Body. I understand why they did it, and not saying it is all that reasonable to try, but I would like to see someone do more than hover the motor over the engine bay.
Get rid of the boost tubes over the top and trim the pan like Boosted did and I wouldn't be completely surprised if it didn't fit under the hood. People put Viper motors in old Mopars and Boosted got it to fit under a Viper hood and I bet they have less vertical room, so it stand to reason it would fit.
Someone did it in a newer Challenger for the Roadnights challenger this year. It would be interesting to look at what he did. Don't think it had a hood, but it might shed some light on how the Hurricane compares height wise to a Hemi from the front part of the oil pan to the top of the valve cover.
