Realistic time estimate on total swap

Man....................Even a 1970 Z in great shape and no visible rust is alot of work..........Inside is gutted and I found alot of surface rust in the seams....Some a little more than surface but not enough to bitch about. A little POR and she will be in business. I have spent 2 solid days with the die grinder with a wire wheel......A little clean up and I will be ready to start with the POR.
