Need more power

Look in junkyards for a six-cylinder ("4.0L" or "4.0 High Output" on tailgate) Jeep Cherokee (not a Grand) with automatic transmission and WITHOUT anti-lock brakes. The rear end in that will USUALLY be an 8.25". The gears will be 3.54's...a few with the towing package or Up Country suspension had 3.73's. (But probably 95% didn't.)

Most square-body Dakotas (1987-96) also had the 8.25"...gears were usually 3.55's, sometimes 3.92's. (Underhood sticker should have gear ratio on it.) The early (1987-88) trucks without OD had super-tall (2.76, 2.94) gears.
