Someone school me on converter/pump relationship please!

I have used a 10" 4000 stall on the street. It is not fun. I had 3.55 and 255/60-14 tires. I t was an expensive converter too. Anyway, dont go buy more stall because it wont idle as you like it. A converter will act differently for many reasons. Cam is one of them. I changed cam in my and it would start to pull on idle even though I had that 4000 stall converter. Before the swap it did not do that on the exact same rpm. So it depends a lot on the setup.

Anyway, I will never go for something with that much stall for a car that sees the street atleast 30% of the driven time. I have a 3000 now and it's just so much better, and it idles just fine even though I have a huge solid cam (282 magnum comp cams) in that little 273.
