Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
The original Bronco was a bit small (it was basically a compact SUV) to compete with the Blazer and Ramcharger in the towing and hauling category so for the second generation, Ford upped its size. This generation of the Bronco was built on an F-150 chassis, giving it more space and, more importantly, more power.
This Bronco came with a part-time four-wheel drive system and a V-8 under the hood. You could choose from a 5.8L 351M and the 6.6L 400. A C6 automatic transmission came standard or you could pick the optional 4-speed manual. This is the last generation of the Bronco to have a solid front axle, making it great for off-roading.
With bigger tires and heavier rims on your list of Jeep mods, the stock gear ratio may not be enough to get you where you want to go. This is where changing the gear ratio comes in handy and reduces unreasonable stress on the engine. If the wheels are too tall for the stock gear ratio, there will be a noticeable power drop off from its stock build.
