93 thunderbird with a 5.0 help please!!

So I would like to upgrade a few things on my T-Bird, and I was wondering what should be the first few things that I should look into first for a good boost in hp at a good price, BESIDES intake and exaust.

Also if anyone could direct me to a good place to get these parts as well, I can't seem to find a good place online that sells parts for this car.

One more thing....will most of the products made for the mustang 5.0 go right onto my thunderbird?

Welcome to the forum NicholasJay. The first things to do are to check the condition of the engine by doing a compression test and connecting a vacuum gauge to it. A 93 Bird probably has a lot of miles on it so it's a waste of money to put performance parts on the engine if it is worn out. A rebuild might be in order. The timing chain is most likely due to be replaced and if the engine checks out ok then a complete tune up is in order. For performance gains the intake and exhaust ARE the first things to change. Next to consider is a chip and gears.
