2.9 Questions
Hello all,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

></o>
<o></o>
I recently bought an 87 Ford Bronco II and have really enjoyed it. Unfortunately the thermostat stuck on me a few days ago and it got really hot (about 160 degrees). It appears that I have cracked a head or at least blew a head gasket :-(<o></o>
<o></o>
It is the original engine with 167,000 miles. Should I just rebuild the head, buy a used engine, or spring for a rebuilt engine? Help please?<o></o>
<o></o>
How much should I expect to pay for a rebuilt engine and where is the best place to buy one? I live in Northern Utah.<o></o>
<o></o>
Thanks!

Well your not alone with the cracked head. These things are prone to that. I just bought a pair of heads from World Products. The bare castings are 170.00 ea. and fully assembled they run 325.00 . As for the buying a new or rebuilt? I found one place around here "Charlotttesville VA" for 2200.00 . Needless to say I'm going to rebuild mine. That's not to say there aren't other options. It really depends how much other damage may have happened to the rest of the engine, I.E. crank, cam, bearings etc. If you haven't driven it since the overheat, you may have to do nothing more than replace the heads.
Good Luck.

It all depends on what you want to do with it. If you want to keep it stock and want it to run better than it did before, rebuild it. If you don't want to keep it stock and want a little more get up and go, swap a 4.0 engine in. I'm searching and saving for the 4.0 swap myself. If you really want to light the fire within the beast, swap a 5.0.

Will a 4.0 swap require many modifications? I assume it won't just drop in. What kind of gas mileage would the 4.0 get? It appears that the 2.9 starts around $1600. How much would I have to spend for the 4.0?

From what I understand about the 4.0 swap, it is a bolt in. "I.E. it has the same block as a 2.9" But you will have to have a donor vehicle. Meaning you will need the computer, air box, etc.... Also, if your running a 4x4 you'll also want to get the transmisson from a donor as well. The Mitsubishi tranny's common to our Bronco II's just won't hold up well.
What are you looking for out of your vehicle? A 5.0 swap may be something else you may want to consider. Basically about the same amount of work.
As for the cost of a 4.0 or a 5.0? Call your local salvage yard. I'm personally getting ready to rebuild my 2.9 . More than enough power for a beater, and the overall cost has got to be cheaper. My new heads only ran me 377.00 delivered !

The most mods you are looking at is the wiring splicing. From what I understand it can be a real headache. Like 1 tom stated there's not that much difference in pricing between a 4.0 and 5.0 swap. The 5.0 entitles a lot more mods to have everything fit though. The 4.0 is almost a bolt in. From what I am hearing from many who did the 4.0 swap, the mileage is the same if not better than the 2.9.
You can just purchase a used Explorer 91-94 and swap out the entire drivetrain. If you do all the work yourself, that will save you a lot of cash.
