What are some good aftermarket dizzys for the 351m/400? Looking for something that is better, durable, and more accurate than stock. What are you guys running and how do you like it? Are there some dizzys to stay away from?
Nothing wrong with stock. They last a long time. Everyone I know who has gone to the HEI style has seen improvement in the way the truck runs. They only require 1 wire (2 if you have a Tac) and you eliminate the box on the inner fender and the external coil. Cleans up the engine compartment.
