Restoring my 74 swinger

If anyone has any better ideas than using the wheels and grinder to sand this bad boy I'd love to hear them. All the seats are perfectly upholstered as well as the door panels. I've switched from benchseats to bucket seats but the center console I have is cracked. The guy I bought it from was going to make it an auto with a 241 Red Ram Hemi. I thought about putting the hemi in bc it is sooooooooooooo beautiful, but i would have to do a lot to get it where I want it. I'm trying to sell the hemi, but I haven't decided on a 360, 383, or 440. Any suggestions? I'm trying to make it as valuable as I can. It's going to be showroom.
