What performance changes have you made to your 5.4 DOHC V-8 Navigator? I'm interested because I'm thinking of swapping this engine into my '48 F1 pickup using the FRPP crate engine. I'm interested in what some Navigator owners have done for performance changes. Superchargers? Cams? Computer chips? Headers? Ford Racing parts or aftermarket and who?

Thanks for your input and interest.
