If you are thinking V-8 swap vs a Hellcat investment. I have a buddy with a hellcat, just upgraded his tune, and is about the 800 hp threshold. There is only one company worth investing in a swap...my guess would be in the mid 30's by the time all is done and done right. Still cheaper than a hellcat and would give a hellcat all it needs. My choice if I had the $$$$ would be buy the hellcat and move on. But there isn't anything wrong with doing business with Accelated Industries either. Both cars would be unique and a handful. Good luck...
