my bronco (old Betsy) has A 4.9L 6l 1bb carb with a 4 speed manual trans with 84,000 original miles. It has about 120 hp with amazing 250 fps of torque . she is one of the best broncos Ive owned, after all these years she still kickin’. I wheel her with the big boys like jeeps with fancy lifts and big tires. Luckly it has a granny gear with a low range transfer case with 4.10s gear ratio in the axles.
