Torque Converter? Where am I at? What is compromised?

My 2 cents;
Don't listen to dedicated 'dragracers' too much. They usually don't care at all for streetmanners.

Driving around with a loose convertor on the street is like your transmission is filled to the top with butter. Feels like a sloppy turd if you want to just go for an easy drive.

Big engine / much torque in a light car means it doesn't need much convertor at all. Just enough to keep the engine happy when idling.
I would get something in the high 2k-range. And make it a 'tight' convertor.

I used to have a 3800 Dynamic torque convertor in my '67 Newport with solidcammed 440. 3.9:1 gears. Flashed at 4300 in this car.
While it's great fun mashing the pedal every now and then, it was getting old quickly having to rev to about 2400 at every trafficlight just to keep up with normal traffic.
