I was reading the post on making the 426 street legal.How does an external stator work.What is involved in installing one. One of the replies mentions an external stator verses a E line stator. How bright of a light can you install with the external type. I am in the process of making my 426 street legal and need all the help I can get. To get better top speed I was thinking of installing a taller 5th gear. Does anyone have any advice on that subject. Thanks.
