Not sure why all new builds has to use the Gen3 ugly hemi.
Go w/a Gen2, with an EFI stack or a TBI so you can put on an OEM-looking Shaker.
I think Dave should have shortened the length of the front end some if you want a tasteful custom. One of the shortcomings of the 1st gen Challenger is that the distance between the front wheel well and front bumper is so friggin long.
