One wire lock-up, 4 spd automatic w overdrive into A-body.

Ok you've got my attention and I'm an idiot on this matter -- what flexplate - torque converter - starter

The flex plate is out of a 5.2 Magnum, as my motor will be internally balance and I need the tone ring that is part of it for my EFI. The starter is just a common mini-starter, and the torque converter is a custom built, 3000 stall, lock-up converter with billet cover and triple clutches from Precision Torque Converters. Basically the engine side of the torque converter is built using 5.9 Magnum dimensions and the transmission side is GM for the LS1 4L60 or 200R4. The overall depth/length is 6.5".

I haven't had a chance to verify exact fitment of the torque converter yet, but will shortly.
