I've having my tranny rebuilt because the Torque converter decided to loose a weight on the bellhousing and chewed the converter up, and they decided to put a slightly higher stall converter in my truck...
She isnt sure the RPM stall, but she said I would noticed the difference, she said it was a has a "K Factor of 145" or 145K Factor, sumthin like that....

Anyone have any idea on what the heck that means when ya convert that to RPMs?

It means that you can kiss your tires goodbye that much sooner.

Okay, I don't have a definate answer for you but I tried to look up some information on the net about it. It seems that the K-factor is a number used when refering to the stall RPM of a torque converter because the actual stall is partially determined by how much torque is applied throught the converter, so a definate RPM is hard to determine. The K-factor is multipled by a constant that seems to be determined by the size of the converter. The only references I found where for GM products and I don't really know how they came up with the constant, but for a 12" convertor in a turbo regal the constat was like 14.25 so estimating off of that would put your stall around ~2000RPM or so with the actual number somewhat dependent on the torque applied.

That is my total knowledge of torque conveters as learned in the past five minutes. If there is someone who actually knows about these things, please feel free to speak up and correct me in any or all of this post.

Hope that helps a little...

 

I finally got SOME info from someone else as well... here is what they had to say...
Basically what you said

I wonder what my stock stall was... <thinking>
