T90s will break anytime they are abused, whether an F or L-134, V6 225, or any SBC V8 engine.
You don't dump the clutch.......
You don't clown around in 1st or reverse.....
pulling stumps out in reverse etc etc
That being said, I ran one behind my 225 V6 for 30 years and NEVER had any problems.

All depends on you and your driving style.
Keep in mind OEM Borg Warner parts are obsolete.
Foreign made junk won't last.
Good luck.

My 47 has a 283 in it with a side shift Bubba adapted 3 speed. I bought a Muncie 420 along with Novak's adapter and rebuild kit to throw in my jeep, strength should not be a problem

Well what I really was directing you to was that not just ANY t-90 is a good candidate for a swap.

Most of the 'normal ' conversions require that a long input shaft (truck or wagon) be used.

They also talk about the strength of the transmission.

Good luck in your quest.

I ran a 327 in front of a T90 for a couple of years with no problems and it was a pretty healthy 327-big heads, solid lifter, 11:1 CR.  A lot will depend on how you drive it and how carried away you get with tires.  It's the old adage you can break anything if you try hard enough but it can work.  The T90 will take a lot more abuse than most people give it credit for, especially in a light Jeep.

I'm fully cognizant that I'm old school when it comes to engine swaps in Willys, but in my opinion, the sbc bets any V6 hands down.  It's nominally heavier and a little bit more of a fit problem but still easy to do and not really any more expensive-all for a lot more bottom end torque if correctly executed.

327 and Muncie?  M20, 21, or 22?  Or SM420/465?  The Muncie car transmissions work well in a Jeep if you're not building something for rocks but even then with a set of Teralows and an engine with a lot of low rpm torque, they work just as well off-road as any of the Jeep 3 speeds.  That said, I would be very reluctant to put an M21 or M22 in a Jeep with that 2.20:1 first gear.

It would be interesting to put that setup in a 50 Nash but it's going to be a lot more work with the unit body.  I still have a 41 Nash 600 coupe sitting in a shed that my father bought new-even found the dealer sales contract for it.  I thought about doing a hot rod job on it but decided to leave it as is.

Also, when I bought my 47 the frame had been boxed completely for strength from the SBC torque. Whoever did it, did it right. You might want to think about that if you decide to put the SBC in yours
My 2 cents
