Which torque converter for 904 and 360 magnum

410 getting weak?
After 4 years of drag racing the crap out of it and spirited driving I have an over 20 lb per cylinder increase in compression!!!

I'll probably go with a magnum motor in my 41 Studebaker. I know I can hook a 904 up to it easily. I may try overdrive but I know the 904 would be a no-brainer for me...
But I'm not trying to talk about my car I'm trying to learn on this one...
