Gear Ratio Affect on Converter Stall Speed
I know that this has been addressed before, but I couldn't seem to find it in a search. Let's say that you have 3.42 gears and a 3k converter and you swap in 4.10's...what effect will the gear swap have on the converter stall speed? Would it go up a little, say to 3100-3200ish, or down a little?

the flash will go down a little.

nope. i didnt really notice anything when i went from 3.42's to 3.90's. but mine never really seemed to flash at 3200 anyway even when i went to a LQ4. i cant seem to find traction anymore either. nitto 420s FTL

The 4.10's have been on my wish list for a long time now, and should be a near perfect match to my planned combo

Do 4.30's IMO
The engine/trans will translate a taller (lower numerically) gear ratio as more load on initial take off and the converter will flash a bit more to do the same amount of work, dropping the ratio (higher numerically) lessens the "load" on the engine/trans and the converter will not have to flash quite as much to move the truck the same amount....
It's very similar to the truck being loaded vs unloaded or maybe even with a small trailer behind it, depending on the gear difference.
