That 47 will never live. You can build it with the 48 5 -gear planetary's, but the weak link will always be the overdrive clutch/spring. You can update to a 48 overdrive, but by then, you could just use a 48...and the 48 won't live either with that torque. You've got options, but none are cheap.

I don't think I'll ever need the overdrive the gearing and tire size will keep me out of it... But any pointers or tricks to making it live longer will be appreciated. Can I keep the 47 out of OD with a manual Valve body? Thanks
Unfortunately no. The OD units clutch is used in direct and OD. You'll still pull through the clutch with OD off.
If OD is not needed, you can just build a 727, or dare say I, a Turbo 400. The adapter on the back of the engine is available in Chevy, Ford, and Mopar. I'd say a Powerglide is out because your going to need 3 gears in the quarter with the rpm band of the engine. If your going to have one built, pick something that has gear ratios available for it. You can tailor the gear split to keep the diesel in it's narrow power band. Probably be best to check in with the Cummins truck drag race guys. They will be a lot more helpful on recommending a transmission and know what will live. I only know what won't!!
BTW, I think your going to want a lot more rear gear.

Awesome! Is that a motor mount/ plate towards the mid to rear of the engine?
