Yep, convertor should be set for 800-1200rpm drop depending.I think that would be very hard to measure. Stall rpm is based on the tq that the cter sees.
You have two things happening on the shift:
- change in engine rpm due to change in gear ratio
- change in tq that the cter sees due to engine rpm change
mine was worse
you must have 4.10s mine was 3.23sWith my setup and shift point of 6200 this is what rpm I roughly see:

I run a 3500 Tight so the converter is not a factor.
But I had a 4000 hard hit FTI that was actually looser with my stroker and my rpm dropped to about 4500 or so at each shift. Lots of slip each shift
I have an 8 in converter that stalls at 5,200 in my drag car. I'll shift at 6,500 and by the math it should drop back to 3,800 from 1st to 2nd shift. But in reality it only drops back to 5,000 or so. 2nd to 3rd shift should drop back to about 4,400, but also only goes back to 5,000.Just wondering eg.. Does say a shift point at 6500 rpm drops to 4000 rpm but your stall is 5000 rpm does it drop the stall 5000 rpm or 4000 rpm or somewhere inbetween ?
