stock 94 5.0, where should i start?

This will get moved to tech pretty quick.

Before that, I'll answer what i can

Cheap and easy route to more power:

GT40 heads, aluminum if possible Classifieds.

Cobra or GT40 intake. Classifieds.

E-303 Cam Ford Racing will have those, as well as 47482 other companies.

Gears. 4.10's. Don't fear the gear. Motive makes decent ones.

Exhaust, get a good midpipe and some headers. Lots of company's make them. For a cat back, flowmasters are your budget's best friend.

As well, lower the damn car. You'll enjoy that both visually and in how the car handles. Eibach and H&R make good kits.

Get some cheap subframe connectors. They're cheap and will make you feel like you're no longer driving a shopping cart.
