I have a 1983 big bronco with a 351w engine. I want to replace the worn out variable venturi carb with a new 2 or 4 barrel carb. What is the best way to go? This is a stock engine with auromatic and is used mostly to 4-wheel and camp. Should I use something like an Edelbrock intake manifold with a 4 barrel carburetor? If so, what models? I also do not have to get emissions tests if it makes a difference.
