Torque Converter Upgrade?

So one of the big things that I have always done with my past cars that were Automatic was a torque converter upgrade. In my old 00 Z28 I put in a Yank 4000 and it was a night and day difference, same story with the LT1/4l60e Setup in my old 86 Firebird with a Yank 3600SS. These converters cost me over $750+ but these made the build and was the one thing I never regretted doing to my cars.

Now my question is for those who have actually done a Converter upgrade, what did you all go with? From what I see, ZZP sells a 245mm but besides the stall speed, they dont provide anymore info.

My other question is about the stock converter in our cars, any info on it?
 


If you're still running the m90, the lowest stall you can get will be best. Lots of people still run stock torque converters with m90 setups. I have a stock TC in my 01.
