Things are moving right along. In addition to Dan at Performance Only working on my engine, yesterday I dropped off the 727 at LIP Performance for a complete rebuild, using CRT's HP street rebuild kit and Cope's Pro Street manual valve body.
My NP231 transfer case came with a 3 pinion planetary, which is load rated at 600 ft. lbs. of torque. That isn't going to cut it living behind Dan's little torque monster, so I located a barely used 6 pinion planetary in super condition, and a long style 23 spline input gear, which is needed so it can mate properly to the 727's output shaft. The 6 pinion planetary is load rated at 1,400 ft. lbs. Once I get the wide chain kit, I'll reassemble the t-case.
