Which stall speed for the Precision converter is best? I know it's a 13" multi disc.

I would be tempted to go with what ever BTS uses based upon the feedback given in the forums about how well the trans pulls.

I wonder what the stock stall is.....

I went with whatever we usually order... LOL

This was back before i worked for DI, but I know it was a few hundred more than stock. That being said, the converter is so much more efficient that I'm VERY happy that I didn't get a lower stall converter. These converters are HEAVY, and therefore, they have LOTS of energy behind them once you spin them up. I think you will like a stall that is near stock or a little higher.

Generally yes (not always).....there is so much that goes into one it can get complicated.

In my Trailblazer SS I had a Vigilante (made by Precision) converter rated at 1900 RPMs that took lots of pedal to move the vehicle. When I broke the snout off the converter I went to a 2400 Yank that drove like stock, was very "tight" but would still break stall on up to close to 2300 RPMs.

Spoke with Precision yesterday. They said that the 1600rpm stall, 13" Stallion is the most popular converter that they sell for the 7.3.

At what rpm does the 7.3 really start making torque?

All my dyno logs are gone when my truck was stolen. Hopefully Jonathan keeps a log of dyno runs. I'll give him a call on Monday.

With a diesel's narrow rpm operating range, you'll want a low stall converter unless you have some exotic high revving, high HP 7.3.

$11 and some change. Plus the HD flexplate at $422.

It wouldn't be a bad thing, but if your transmission were to take a dump and send metal or whatever through the converter it might not end well.
