Several options. You could rebuild the TH350 with a manual valve body/shift kit and you'd have a trans to shift, but just no clutch. If you want to launch a little harder add a trans brake to that build.
You could also go with either 200r or 700r4 and also a manual shift kit, then you'd have the shifting and the overdrive, plus if you went with the 700r4 you'd have a granny first gear with those 4.11 gears for a real launch!
Or go with a T56 5 speed or 6 speed and get a good hard launch, and overdrive for the highway.
Yes, your Camaro is heavy, and it takes a bit to get them moving, but I'd guess my '71 with 427 is a bit heavier and I'm running a 3.42 posi without suffering acceleration, or top end. Mine's no barely legal street car, but still runs low 12's with street tires, at around 118 mph. And it's running a TH350 built to handle BBC torque.

The car is too heavy so most of the parts will eventually break,including the clutch.
How did you arrive at the 400 horse power figure?
the 400 horse power mark is what me and my engine builder settled on when i brought him my block and my 91 corvette heads......

I'd run a turbo 400 auto and keep the 4.11's.

I'd most defanatly rather have an auto on a street car over a manual. Get a turbo 400 with a good matching converter and a good shift kit, get your shifts tuned to your car and you'll be good to go.

My corvette,I converted to a TKO 5 speed and gave a local kid the old 4 speed.I dont drag race so the standard is for fun sport driving.
For drag racing I would use a turbo 400 if the car was a regular street car and probably a powerglide if race olny.
If the car was really something to look at ,I might consider the TCI 6 speed auto.The car would have to be worth the investment.as $6,000 is a lot more than $800 for a turbo 400
