727 converter choice

I have an M-code GTS that I’m building an engine for, and I’m trying to figure out a decent torque converter. The engine is a 69 440 HP, factory steel crank and connecting rods, KB237 .030 pistons with Stealth heads, Mopar Performance .528/284* camshaft, roller rockers, aluminum water pump and housing, CH4B intake, AVS2 800 CFM, 3.55 gears with a Tru-trac locker. The twist is I’m keeping the original M-code manifolds. It should all look stock but have a bit more grunt, and it’s not an all out effort, just something fun. I’m curious what people use for a converter with the .528 solid. Lots of lift but reasonable duration, [email protected]. I’m not looking for something super loose, just something that will let it idle decent.
