No one can say. its a used converter and without it being sent out to be cut open and inspected, you are taking a risk.but will be ok in a stock engine/turbo combo? how is theese too drive with, need much rpm to get truck moving? running 35" tires, and stock one need enough rpm to get truck moving.
I wouldn't think its stator would survive many 2nd gear starts.
Mine was a pleasure to drive locally day to day, but with the larger charger I just blew right through and wasn't putting power to pavement when I'd goose the loud pedal. I lived with it for about 5 years, through the use of a lockbox. My current converter (1077) makes the truck feel a bit laggy (Mark revised the tune and made a huge improvement for me!) but at any given moment, the ratio of hp reaching the tires vs hp out the tailpipe is a hell of a lot better, LOL.
Brad, the reason Mike stopped using them was b/c better options came out later on, not that they werent somehow "no good". There's a reason those converters were called "MikeL" converters for a very long time, and still are to us old-schoolers. But, one thing Mike never did was to "stand on his laurels". He was constantly trying to find something better, which helped all of us.
I had one of the first 10 "pink" Precision converters made. 100s of passes in the 12s.
It also doesn't help that you have a 68r and a 2000 stall converter, the 1078 or Goerend R/DL/DK/BF would have been a better fit. The 1078/R/DL/DK are 2300rpm stall and the BF is around 2500rpm.
I wound up with the 1077 by a fortunate accident. I built my truck and a buddy's identical truck with the 1078 - all things being a compromise, I like the 1077 better. It's personal preference not really right nor wrong. As for the other converters that you mentioned, I can't speak to any except the R - it was terrible on my truck. I blew through it so badly that I was just shocked. On a stock truck I'm sure it's great, but it's a terrible choice for my truck. I've had direct experience with my truck spinning a 777, Precision ML, R, K, 1078, and 1077 - the 1077 is the best compromise for my truck and my satisfaction. Others may disagree, but I'll bet few have the breadth of experience with all these converters in their own truck, LMAO.
FWIW, stall is a wonderful reference to discuss converters, but it's only a small piece of the overall picture, and stall is also a moving target - my 8000# empty truck with 700hp will stall differently than someone else's "same" truck with different weight and power. Since there are so many variables, I'll wager that what we read in product literature for stall speed is with a stock truck and bears little real-world meaning once you get to where a lot of us have arrived with our builds. Still, it's a good way to compare one feature of the converter in a relatively common language.
