Anything but the stock fuel pump.
At least an alphabet cam (i.e B,E, or F cam) While you have the timing cover off go ahead and change the double roller timing chain.

Thats if you want to do it right.
If it were me and I wanted the most HP for the cheapest price

Milled GT-40P heads with Long Tube headers.
Explorer intake with a ported lower and 65mm TB
B-303 cam
190lph fuel pump

If you look around all of that can be had for $1,000.00 bux Not bad for a low 13 second car with gears and slicks.

JMO,
I agree (I guess I would - this is what I'm doing to my car), but I would pay the extra money and buy the Crower 15510 (auto) or 15511 cam (T5) for $250 from Powered by Ford.


T5 - F THAT - that carbed engine makes power above 4,000 rpm - not my idea of a good, powerful, street friendly driver. Most of our cars weigh WAY more than yours. Carbs and short runner carb intakes are good for peak numbers - compare average area under the torque curve for the real picture in comparing two engine combos.
