gear change affect stall speed i am wanting to swap out my 4.11 gear for something a little more highway friendly like say a 3.42 or even 3.23. now the car stalls at around 3500 rpms. will a gear change like i want make the car stall higher or will it stay about in the same rpms at cruising speeds? just trying to figure out if it will be pointless to go to such a higher gear ratio if the rpms are still going to run the same. this is with a t-400 trans also.

From my personal experience, when I had a 3200 converter, it took between 2500-3000 to get moving with Hedman Torque Step headers and 3.23s. I changed to an LPP header with bigger primaries and getting to speed took around or a little less then 2500. I then changed to a 3.73 and it dropped to about 2000 or so. So less torque and/or more gear tightens the converter up.
