Don't think it needs anything done on bottom end. Not looking for a radical cam. Would I need to add a bigger torque converter?

how much weight are you towing ?
I would replace the cat converters.. could be plugged damaged.
also with power issues I would measure fuel pressures. clean MAF CRC MAF cleaner.. and the throttle body.
I tow 4000 lb 20 ft boat no power problems.
when I do tow I use 89 octane.. 87 is too low..tow only in 3rd gear ..if you do OD the tranny will overheat .
