I saw headers in the new summit catalog for the 97 4.6. They are $159! I really can't see spending more than that. My casts are shot, and I've been looking into this for a long time. I also say them at www.steeda.com for a reasonable price. I can't do the JBA's because of the $$$. It's just dumb. The shorty header change was dyno'd in at www.modulardepot.com on the 4.6 and it gained a whopping 2.4 HP! WOW!
It would be nice to see more posts and less views for a change. I'm not the only one that can't justify $650 for JBA's.
