I placed a 2006 5.7 Hemi under the hood which ment I had to make my own firewall because even big block after market firewallws wern't wide enough or go back far enough for that motor. And of course that set up a lot of other opportunities for further mods like building a floor and dash from scratch. It will be a very expensive and long project but I would almost bet my life that nobody else will have a car quite like it any where. I also cut the sides off the hood and made mounts for them using the original latches then welded the hood together down the middle and made a frame for it and hinged it in the back so it will open like a modern day car. I think I have more time in the hood then I do any other part of the car.
