Well, I've always wanted to see a 4BT in an OBS Tahoe. Couple it to a 6 speed Allison auto and I'll be impressed.

That combo would bring some amazing MPG's!Well, I've always wanted to see a 4BT in an OBS Tahoe. Couple it to a 6 speed Allison auto and I'll be impressed.
The tank won't fit.
A 700R4 either has a mechanical or electronic speed sensor. If it's mechanical, you're SOL. If it's electronic you'd need to find some way to make the signal work with your gauge cluster. It probably won't in the end because of the pulse rate.
Listen to what you're saying. You're going to wind up with an unreliable jalopy that I wouldn't trust to drive 5 miles for a gallon of milk. Either do it right or don't even attempt it. With a fresh 5.7L in that Tahoe and a tune, 20mpg on the highway is perfectly reasonable. If my 5.7L rcsb can pull 23+, it can be done with a heavier SUV. It all boils down to the fact you aren't going to get even CLOSE to your mileage number in the end.
Other option: scrap both vehicles and buy a fuel efficient car. They'll still pull an apartment worth of stuff if you're concerned about moving. People in Europe do it all the time.

DO you asked for people's opinion's but have already made up your mind? Why did you bother to ask.
Ever get the synchros in 3rd replaced? Who did the swap? Still have 9" of lift?
If you're wondering, I'm leaning back towards putting the gas engine back in since I've learned 20-23 mpg is not out of question on these engines. The 16 mpg EPA rating really scared me. As I said earlier, the plan for this vehicle is to put a lot of miles on it so fuel economy is extremely important.
I've learned to double shift it into 3rd gear. It's a little bit annoying but it does the trick.
I bought the truck this way.
Yes, it still has the insane lift. I'm amazed that it still pulls mid 20's as far as gas mileage is concerned.
