The power loss in a drag race is made up for with the torque converter's torque mulitplication and the consistincy of an automatic's launch and shifting. Consistincy and torque is the name of the game in drag racing. And since there's only going to be one shift with a powerglide the shift can set so fast there's no need to manually shift. You could pick up a little with a manual in a drag race but the inconsistency probably wouldn't be worth the trouble. I don't see any reason why I Turbo 350 or 400 couldn't have a full manual valve body.
Even in road racing some of the advance manual transmission have automatic clutching and shifting. I don't think a manual automatic makes much sense for road racing. A 3 or 4 speed manual transmission would give you more advantages.
