Another "which stall speed conv" thread!

Transgo's are OK, but if I had it all to do over again, I'd skip the shift kits and go straight for a valve body. Lentech rocks.

As for the torque converter, you're correct, the stock converter stalls arou8nd 1500. I'd recommend a minimum of 2500 rpm. Most of the higher end converters are a little pricey, but you get what you pay for in this case. With a 2800 rpm non-lock up and 3.73's, I cruise 70 mph at 2500. 4.10's will raise the cruise up a couple of hundred rpm, but the car will perform better.

I'd say a 2800-3200 rpm lock up converter with a Lentech VB and a set of 4.10's and that thing will FLY!!

One thing about converters, if you're running an aftermarket cam, it's a good idea to talk to the converter folks to see what stall they recommend and power bands vary widely. The main thing is that you want the converter to allow you to reach your power band as quickly as possible. If your power comes on at 2700 rpm, a 2800 rpm will put you right there. Another thing to consider is that a converter that stalls around 2800 rpm on a stock motor may stall a bit higher on a modified car. Call up Precision Industries and talk with their tech people. They can give you good advice.
