Zex has a Kit made just for the 4.0. They put one on a project car on American Muscle. Made good power too. But I was wondering what all they did to install it other then the Kit install. Like Different plugs or maybe a tune or what. Any body got an Idea?
I would stay away from a dry system, wet is the way to go. The only thing available is going to be a nozzle system, no plate systems available as of yet. Nitro Dave's does do custom plates. Tune & fuel system is going to be determined on how big of a shot you want to go with. Rule of thumb is, take 2 degrees of timing out for every 50hp of spray
