New Project: 1st Part--JRS Subframe

[catz]

Starting a new project-69 Camaro 408 LS Turbo. Received my new subframe from Jake's Rod Shop about a month ago (see pics below). Currently have subframe bolted in car for turbo mockup. I'm waiting for the rest of the parts to arrive from Jake's to complete subframe install. Will update as parts arrive and progress is made.

Still not sure what to run for transmission or rear suspension-any advice?
Motor on pump gas should be about 800HP.

Alot of guys are pushing for automatic-any suggestions are appreciated!
