Tex, thanks that sounds like good advice. The motor is going to be removed, rebuilt, and reinstalled. I think I may have to look into the cam and headers. Also in your opinion, is it even worth it to go .30 over. Are there any negative points to boring out the motor?

Generally they are going .30 over since it is a rebuild and they are honing the cylinders. It is the first incremental step in rings/pistons etc. The only negative point is if poorly done. From your posts, they offer a warranty, make sure it is in writing. Look closely at the type of driving/terrain you will be frequenting in 4wd. By the way, the Bronco will make an excellent family car. Some do not like the access to the rear seat, I never had a problem, and due to layout, my wife could hop in the rear seat with the baby seat in back and travel well, view is unobstructed and she tends to get motion sickness, not in the Bronco, though. You can also leave the passenger seat folded forward and to the front and she can prop her legs on the back like a recliner. A little tip from an "old Dad": Make her comfortable with the truck and any mods will be to the family vehicle, not "your truck". It works, believe me. Look at all modifications as an investment in the truck's future reliability and go there first. The lockers, lifts, and tires will come. Right now your concern is a very safe reliable vehicle for your family, I think you made a good choice in the Bronco.

you must get a computer friendly cam for this motor because your bronco has speed density. most any cam will work if the lobe seperation is no less then 114*. any less and you will have engine issues an it will run like crap

So what is the stockcam? All I've heard so far is it's a roller cam. What cam, who makes it and how much does it cost? Will there be a significant difference between the stock cam and an aftermarket cam?

Cams
A stock cam is designed towards overall driveability. A cam that is designed to produce more torque will compromise in another area of overall performance, generally in the high rpm horsepower generation range. As Kem pointed out, the cam must work with the specific type engine system you are running. Cams are spec'd in lift/duration/and overlap. Lift is the amount the valve is actuated; Duration is the amount of time it is actuated calculated by the degree of affected rotation; Overlap is the amount of time (again based on degree of rotation) that the valve operates while another valve is actuated. With the baby on the way, 
your expenses are going to take a significant little jump. Stick to a stock or slightly improved (for torque) cam. Now is not the time to go radical. You will need very dependable transportation with the munchkin involved. I apologize, Congratulations! on your addition. There's nothing quite like it. After 26 years in the Corps and a lot of living, my daughter is definitely the best thing I have done. I now know why I was allowed to survive some things that I shouldn't have. The best part, even with all the work, is coming. Again, congratulations.
