i bought an Air Raid intake system and throttle body spacer. it cost just over $300, and it feels like i have a new Jeep. it was very easy to install, took me less than an hour. i have 33 inch tires, and my 4.0 had a hard time keeping up in fifth gear before the install. now my power is better throughout the rpms. generally, any time you decrease the airflows resistance from intake to exhaust, horsepower, gas mileage, and throttle response is increased.

some say 420 others say 425 but its around there
it makes you exhaust louder or " meaner " and some say it causes an increase in horsepower
it is hard to say considering i do not know the specific car, but here are some general mods that will improve general preformance and horsepower....cold air intake, exhaust system, new cam, bigger gears, port and polish heads, supercharge or turbocharge it(this will be pricey $1000+ but will add near 100 more horsepower), new ignition wires(faster throttle response), and the always stated, what you dont need, get rid of. Overall, i suggest getting the cold air intake and exhaust system. these are probably the cheapest and will make your car much more gas effecient and will add SOME horsepower. hope this helped:)
Some do and some don't. Jeep sells then with your choice.Some do and some don't. Jeep sells then with your choice.
The 1968 Pontiac 455 engine produced 360 horsepower in its standard configuration. This engine was known for its impressive torque and performance, making it a popular choice for muscle cars of that era. Additionally, some variants and performance packages could increase horsepower slightly, but the standard rating was 360.
The horsepower of a Ford 351 Windsor (351W) engine can vary based on the specific model year and configuration. Generally, factory versions produced between 1969 and 1997 range from about 250 to 300 horsepower. Performance modifications and aftermarket enhancements can significantly increase this output, allowing some builds to exceed 400 horsepower.
Some Jeep Models have them.
A Chevy 305 with a roller cam will have MORE power than a 305 with a flat tappet cam if both are installed in the same engine. The horsepower of any 305 depends on what all is done to the engine. Changing from flat tappet to roller will gain some. There are other ways to increase horsepower and there are other ways to increase torque.
the easyest/cheapest solutions: a 4barrel carb a 500-600 use the crank of a ford 302 engine buy some racing headers and maby a exaust use smaller gaskets to increase compression
a K&N air filter will probably help some with Hp and it will also increase your gs mileage!!! good luck!!!
Depends on what year. Some are mounted on the rear door. Some are mounted inside the rear of the Jeep. Some are under a cover in the floor of the rear. Some are mounted under the rear of the Jeep.
