I want to know if they changed the size or if they just changed the angle of the fins inside to increase the stall speed of these.
Best, James

I believe I have a rebuilt 300J convertor, by Long. Just in case. Stock high stall are almost non-existent. GM bodies are plentiful. Chrysler convertors were welded, GM's must be furnaced brazed to strengthen turbines. Rick From:

I never could find a factory spec on the stall speed for the J or ram K converter, but I seem to recall that we guessed it was about 1900 rpm. Don Verity might know? Yes, stock J and ram K highly modified from normal T-flite.
My J trans was rebuilt with a 2500 rpm high stall converter and a '71 and up pump. I was talked into this by a local so-called T-flite "expert." I think he was thinking '71 426 hemi trans not letter car. Anyway, I would do a stock converter on a do-over. Any kind of launch from a dead start just burns up one of the rear tires (no sure-grip on this car!) and the trans will shift up 1st to 3rd if too much wheelspin. Trans shifts extremely quick 1-2-3 at low rpms even with linkage adjusted properly, need deeper throttle to get high shift points but need to avoid wheelspin. So better to nail throttle at say, 25 mph, downshifts from 3rd to 1st, slams you back in the seat but not too much if any wheelspin. Slip is very evident on low rpm starts, fuel economy sucks. John is correct, however, that it doesn't slam or stall engaging drive or reverse and I have curb idle set a little high at about 850 rpm with today's gas. Running somewhat stock cam (unknown specs), PO converted to hydraulic cam setup (I like that, who wants to pull rams to adjust solids?)) with '62 Imperial 4-bolt heads (1.60 exhaust valves instead of 1.74), running stock 3.23 rear (maybe 3:31, per build card, not sure).
IMHO Chrysler engineers knew their "stuff." keep it stock!
