Last year, I rebuilt a '70 C6 (from another F100) with a TCI kit, new bushing kit, new one-way bearing assembly and added a new Hughes 2200-2400 stall speed converter and flex plate. I also started a 390 build beginning with a 0.030" overbore, 0.010" decking, and a line bore to tighten up the oil clearances. I had the crank turned 0.010" and polished and the rods re-sized (big end) and re-bushed (small end).
All of this stuff was slated for the black '69 but I recently bought a very clean, straight, and rust-free '70 without a motor or transmission...so, all of this new stuff will now be finding its home in the new '70.
