It all depends on what years you are comparing. Newer engines do make more horsepower because of technology. Truck engines like the Bronco 5.0 you're asking about aren't designed with high horsepower in mind. The idea behind them is reliable life and torque. Raw horsepower numbers usually don't mean squat by themselves. It all depends on the application and the intended use of the engine that matters. The numbers sound about right to me. An early 90's Ford 5.0 in a Mustang was around the 235-250 hp mark. Look at what they're turning out now with a smaller engine!
That's great! See, I knew it could put out the power with the right hardware, but in stock form on the Wagoneer it was really weak. Of course, all engines were weaker 12+ years ago, but 140hp out of a 360cu.in. V8??

the 302 is actually made for high rpms. It has a short stroke and a large bore.
most hopped up 302s with a stock bottom end (rods, crank, bearings, etc) can run to 7000rpm without too much problem
Essentially, minus the 289 (302= stroked 289), not really many -if any- other engine is designed for high rpm (physics wise).
Ford puts a itsy bitsy cam in there to make torque , but it hits a huge wall at 3400 rpms. Put a mild cam, headers, intake and new carb on it and it will run to 5500 strong and produce about 250-265 horsepower easy. (nice torque too...)
there are a ton of parts for this motor too... and they are pretty simple to work on.
FOr not much money you can make an awesome 302... which is much lighter than the new breed of ford overhead cam engines.
check out edelbrock for a few dyno runs of the engine
Again, remember that the more HP you make, the higher in the RPM band you will be. With a cooresponding loss of low end torque. Be sure to decide what you want your engine(Jeep) to do, then build it to that application. When it comes to torque, THERE IS NO REPLACEMENT FOR CUBIC DISPLACEMENT!

I'll second that.....exactly why trucks made for pulling and "work" came thru with large displacement engines....360s & 401s in Jeep Trucks, 460s in Fords, 454s in GMs, etc etc.
Not that smaller V-8s are not sufficient for pulling or working, but the larger ones work much less at developing the torque, and will last longer under stress. (Or just go diesel, LOL)
The big thing with the 5.0 efi motors, is the design of the EFI intakes. They use a very long runner, to make alot of torque for the size motor they are. For instance, the 5.0 H.O. in my mustange makes 225hp@4000rpm. and 300ftlbs@3200pm. The main reason for this is the long unners.
I would say forget the bronco motor and go for the H.O. I paid $200 for a running lincoln mark VII had a 5.0 H.O. with 165K on it, not even broken in.
Also the H.O. motors have a roller cam, and forged pistons. You can find them in 87-93 mustangs, 86+ Lincoln Mark VII's and in some thunderbirds..
