Is this torque converter useable?

I get what you're saying but, there are several brands ranging from $250-1000+. I'm trying to figure out why a $300 B&M is better than the $100 parts store TC. Besides that, the performance ones all seem to be higher stall. If you were to suggest a stall for this 3300lb truck with a 440 RV cam, 3.23 gears, what would it be. I was thinking 1900-2100 stock range but, I've never driven or owned anything with a high stall. Craig

It's not. I wouldn't run a B&M for love nor money.
