Getting Transmission Rebuilt

How about the torque converter?

I might not re-build the engine for another year or two and it will be even longer by the time I get the rear end gears done.

Most cams obviously have specific specs for these two. The ones that interest me require a 2200+ to 2500+ stall.

Is it better to leave my stock torque converter in there until I get all those other things done?

Thanks again everyone for suggestions on this.
