Grumps has it pegged. As for builds BH blocks are considered the best by some. Heads- 68-74 is my favorite era. My take on blocks-Just look for minimal core shift and build it. Cranks- look for one that doesnt have deep holes in the counter weights. Cast crank engines are lighter 76-80. I dont have enough experience on the Hydro 81-up to make a call.
