2300RPM-stall, locking torque converter on STOCK-REBUILT 700-R4 (on a wussy v6)

I was just wondering, since a shop I was talking to about getting my tranny rebuilt, told me that I could choose a higher-stall torque converter.

the question is.... will a 2300RPM-stall converter help me? I know I don't get much of a launch unless I powerbreak it to over 2000RPM--as it is, with the stock converter...

so what do you guys think, would a 2300RPM-stall converter help a wimpy v6 out at all, or should I stick with the stock (1600RPM-stall) converter?

I just figured... while I was getting it rebuilt, I might as well swap it, if it was beneficial.

thanks,

Steven

does anyone think this would actually hurt my performance? or wear the tranny out faster, or hurt anything in any way?

the higher stall would slip more and will creat more heat. more heat leads to a shorter tranny life. so yes it can hurt something, the tranny. a 2000 would be better. most of the newer 94+ v-6 f-bodys come with a 2000 stall.

this condition is much more prominent when the convertor is below it's stall speed. ie crusin below 2300rpm (lots of slipping going on).

on the highway, I'm usually way under 2000RPM.. should I just get pure stock stuff?

you can get away with it as long your TCC lockup system is still working.

well, since I'd bet getting a new converter, (or a rebuilt one,) this doesn't seem like an ussue.

is the performance really that significant from, say, a 1600, to a 2300 stall converter? will I lose any driveability?

I know my brother has a 3000-stall in his muscle car, and he can still drive around at low RPMS, just seems like it's less efficient at that point, because like you said, it's slipping.
