Nutshell version of the 82 J-10 ;)
-Motor 258: good motor...bad carb(carter BBD).
-Trans: T-176(ok), T-5(poor), TF727 with the 3.31 axle gears. TF999 w/2.73 axle gears.
-Tcase: either the 219 w/AT or the 208 w/ or w/o AT. Both are good x-cases.
-Front axle D44, Rear AMC20. Front has unlocking hubs w/np208.
-2.73 gears or 3.31 gears, the 2.73's are ridiculous in a truck for hauling or towing but you can live with the 3.31's.
-Body: no traditional J-truck eyebrow over windshield :(

Edelbrock made a SP2P manifold for the 258, which would increase low end torque and allow a better carb to be used. Very durable motor.

I tow with 2.73's (and 360). My truck was actually ordered with the tow package and 2.73's. The original owner was an AMC dealer, and had to pull strings to get the 2.73 AND tow package. The 2.73 may be anemic with the 258.

NO GARY I HAVEN'T SEEN YOUR OTHER POST YET. BASICALLY A STOKED MOTOR WILL GIVE YOU MORE BOTTOM END TORQUE BUT IT'S A PLUS AT BOTH ENDS.
OLD HOT ROD ADAGE " IF YA WANT MORE INCHES...STROKE IT" ;)
I LOOKED A LOT INTO THE 4.5L-4.7L STROKED 4.0L USING A 258 CRANK AND IT SOUNDS SWEET. IF I EVER STUMBLE ON TO A CHEAP 4.0 OR THE ONE IN MY XJ GOES SOUTH I MAY GIVE IT A TRY. THE FSJ'S BUILT IN MEXICO USED A STROKED FROM THE FACTORY 258 AS STANDARD EQUIP BUT THEY'RE NOT AVAIL IN THE US.

IF YOU DIDN'T SEE MY REPLY TO YOUR OTHER POST, GARY, THEN ASK THE MAN FOR HIS LIST OF RECEIPTS FOR ALL THIS WORK. IF HE SAYS THE PO DID IT ALL, THEN I'D BE WARY.
