I called the trans shop this morning, and talked to rhe owner. He said the trans is out of the truck. I asked about the warranty. 2 years or 24,000 miles. We had talked torque convertors when I dropped it off last week. Yes its getting a new one, but nothing all that special. He told me last week, if I was going to do a cam, that I would need a stall. I already knew that, so I said, I will swap it out latter when I do the engine, but that wont be soon.

You could do the V6 converter while it's apart.

Agreed. I also used he 4.3 converter. Stalls at 26-2700 behind my big block. Probably 3-400 lower behind small block. But under light throttle it feels like stock, so you're not always running around at 2500 rpm.

Would that be good for a daily driver?

Yes. It's good for a daily driver unless you do some HEAVY towing. It will put your RPM's into the peak torque quicker, but will build more heat with a heavy load. Light towing of a utility trailer or average boat would be ok.

Heat from a higher stall is irrelevant once the converter is locked.

can someone explain how the torque converter works and what the "stall" means? this part of the transmission is somewhat a "mystery" to me. I understand what its basic function is but I cant quite picture how it works. I guess I could probably find one of those really oldschool and really cool GM videos that explain these things in great detail so that everyone can understand... like the differential one.

Picture one fan powered by the engine blowing into another unpropelled fan that is connected to the transmission. There is no mechanical connection which is why your truck is able to idle in gear at a stop. Different designs allow different degrees of slippage or "leakage" and also efficiency. Instead of blowing air, you're pumping ATF. There's another component involved, I forget it's name, but it has the same as putting your finger over the end of a hose to squirt the water farther. This part is essential to the off idle stall. Once spun up, this component is largely taken out of the equation which contributes to high RPM unlocked efficiency. There is also a clutch inside the converter that, when locked, eliminates all torque converter slippage and increases efficiency and keeps the transmission cool. Once locked the vehicle behaves more like a manual trans.
