There are 2 ways to do it roughly. Or 2 I looked at when I was planning my truck as I had a chance to swap for a 4L65, and a NP208.

1. Buy adapter for a 700R4 to your transfer case, move your assembly back a couple of inches, get new drive shafts or have yours adjusted.

2. Buy a NP208 or NP241 with the 700R4 transmission, move everything back, and get new driveshafts made or your adjusted.

Which is why on my truck the working plan is now too put 3.42 gears in my axles, and get my TH350 rebuilt with a wide ratio kit. Also when the tranny gets rebuilt have a few upgrades done to increase strength. My tires will either be 32 or 33 inches tall, and I will have a highway rpm of roughly 2500 at 70.

My current 350 has bolt ons, and stock cam. So torque should be more then enough to power her down the road, and take off with a 6000 pound trailer. Eventually I may up it to a 350 Vortec with a cam or a LT1 to gain the roller cam, and power.

Another idea I has was to use the 4.11 gears, and build a 327 or 302. Both of which are more rev friendly on mpg, and the deeper gearing makes up for the lack of torque.
