What is a good stall to go with a 3:23 Sure Grip?

I edited my first response regarding the intake pictured...

I deal with and have dealt with this FOREVER. People will spend 10K+ on the biggest baddest engine they can build, then put the cheapest junk $200 POS converter behind it. Then complain that the car doesn't run right.
In an auto car, the converter is basically the single most important part of the combination. Gears, tires whatever... converter!

TCS is good and in your country. I've bought more than a few things from them over the years.
Really appreciate the feedback. Thanks!
