i got a 84 bronco it has a new balanced 302 with all new internals an cam with 204 intake an 214 exg so i wanna know whats a good intake manifold to get and carb where i can get the most power and what gears should i change to?
What is the rest of the engine build? How do you plan to drive it (wide open, rock crawling, etc). As for gears... depends on the tire size. Most go 4.11 with 33's and 4.56 with 35's. Those may vary a little.
38's? Stock running gear? 302? Mud / sand? Probably not the best combo. I would look at a bunch of other rigs here and see how they were built. For all around performance, I have seen the Eldebrock Performer packages work well and they are good for a daily driver.
