Yeah, RWD conversion would probably be a must. Not sure what the size of the new v8s is, but they are not small like an LS motor. You’d be cutting up a bit of floor to make it fit, but if you could fit it between the grille and the firewall, it wouldn’t be too terrible. But if the firewall needed to be modified, yikes! At least with the stow and go, there is probably room for the driveshaft and rear end without too much hassle. But the center console area would get butchered up a bit for the transmission.
