What Non mopar mechanic work are you doing

Ways to go, but have all the stuff. Just need time. Front wheels are just for moving it around, i have matching slots for the front. It is my boys car and he wants to out some miles on it before deciding on how much to chop it. We have some cool plans for little things. It has suicide doors, 460, C6, and 9" with 4 link and coil overs. Engine came from his grandpa before he passed so he insisted on using it.

what all is involved registering something like that? Do you just go by your states street rod specs?
