4.0L mods...and questions..

[Mrburns]

So has anyone ever rebuilt the top end of their 4.0L motor with 4.0L HO parts? I wanted to change the head over the HO head for better performance and greater aftermarket support....Anybody do this? does anyone know any problems involved with it? wiring...cables? etc.... Thanks

Yes it's been done. Everything from just the head to head and intake. In CA it means you will have to let the referee look at it and it will be smogged as a newer one if you use the intake and injection. The guys on the Yahoo Groups Stroker forum can answer more specifically. Almost anything will require modifications of some kind.
