Looking @ getting a new torque converter when i put my new camshaft in my 468. Right now i have a 2400-2800 in it. Here's the specs of my engine
Speed pro dome pistons
Wolverine blue racer solid cam
~3200-7500rpm
~.595/.621 lift
~320/330 duration
990 heads w/ 2.25/1.88 valves
Single plane intake
750dp holley
Cast crank
6.185 truck rods

5.13's gears
TH350
NP205
Unknown weight of vehicle

Rough guess from desktop dyno says..
578hp @ 6k
549tq @ 5K

I've read that your suppose to go 500rpm below the peak tq. It's mainly gonna be for mud runs. But i don't know, just looking for some input.
