A longer runner intake will help you on the low end. A intake like the comp breadbox has zero runner lenght. It wont make power until your over 2 grand. But will out flow anything Ford wise up high.
You may see a marginal change in performance with a different intake. The power will mostly be moved up the RPM's with not much gain. You need a cam to take any advantage of a intake.
A set of roller rockers is a great bang for the buck. 1.7 are good for 5 hp on stock. This will simulate a bigger cam. Also taking power higher into the RPM's.
A 4.10 gear seems a little steep for the street. I run a 3.55 and almost have no first gear. But still get 24 mpg.
