? about stall for current setup
If the answer is something misguided like an incorrect belief about fuel economy get over it.
Proper stall and gears even 3.42-3.73 can make a dramatic improvement and will be required before any later cam considerations.
I made the mistake of cam before stall/gears/headers and even 2800/3.42 was a HUGE improvement from 1400/2.93, and with the 3.43/2800 setup I still put 20K miles a year on it.
