Been a long time ago, but I had one set up for Chevy engines back about 30 yrs. ago. Don't have room for one now, so I do it in the car. Mine was made from 2"x2" angle iron, and had a console with oil pressure, water temp gauges, tach, on/off and start switches. I also had a battery box to hold the battery. The radiator was an old Chevy truck large radiator to handle most engine temps, and I kept those flex hoses on it to adapt to most Chevy engines. Had wheels with wheel locks on mine so I could push it arround easily. I used the side motor mounts and bellhousing bolts to hold the engines, as Chevy locates all their SBC, BBC, and some 6 cyl. engines at the same point.
Hope this was any help with your questions?
