I would do a
aftermarket lid used in classifeds
Ported tb
all the free mods
Pacesetter headers and ORY (could be used)
That will get a little over $500 but it will really wake that car up.
OR
If you want better track time tho you must go with a stall, and some 3.73 gears.

there are kits that are less than 500 but the problem is they are limited to how much u can spray, so if you decided in the future you ever wanted to spray your more you have to re-buy another kit and basically start over. do it right the first time and get a nice kit. id advise a plate kit but thats me
