Just figure it will be the weak link and dont be surprised IF it breaks. Just have a back up plan if it does.
This will be a very fun and attention getting Jeep.
thanks Ron, all good points.
lets just say i would drive it respectfully since i need to count on it.
i may have meant my question to be more generalized than it came out.
sure the trans is 50 years old and i really have no clue of the condition of it, that not what i meant to be asking.
if i could get some input from those who have run a like swap that would be great, i just dont care to be going through them like there is no tomorrow.
this would be a t90j that willys trusted enough to run behind the tornado which does not have power number "too" far off of a stock 2 brl truck 283. but maybe that extra bit is enough to trash the thing.
i am not really sure of the differences between the a, c, and J in reference to t90 variants.
i have never rebuilt a t90 or looked in one, but if they are anything as easy to rebuild as t5 i would not be opposed to having a spare to rebuild on a rainy day to put on the shelf for when the time comes.
