Can you replace a ford 2.9 in a 89 Bronco 2 with a 4.0?

Can you replace a 2.9 in A 89 Bronco 2 with a 4.0? An how much of a problem would it be. Do i need to switch out trans or transfer case, fly wheel, rear end, ect, any help would be great thanks

Way too long of an answer to post here, but here is the site that does have the instructions for swapping the 4.0 into other ford vehicles including the Bronco II

Pretty major job for a non-mechanic, but not so bad for an engine swap.

You do need a donor vehicle and not just an engine - you will need the transmission if it's an automatic and most likely if it is a manual

Thanks for the site it helped out a lot. Now i think i will just rebuild the 2.9 with maybe a little boost. I don't stump jump or drive off rode like a crazy 4wheeler on bad steroids. This is my hunting rig and the motor is just plain getting tired.So who or what do you recommend in ways of rebuild. Crate it or kit?
