Wanting some more power out of my 3V but don't want to upgrade to a new car. What is the cheapest/most effective route? I already have basic mods like CAI and tune, but just not getting the job done.

Stroker kit means taking the engine all apart. Unless you know how to
build engines, isn't an option for anyone. Unless, of course, you pay
someone to do it. You'd be better off with a supercharger or procharger.

A stroker kit will give you extra torque and power, you can pretty much calculate how much more power by comparing the new displacement to your current displacement. for example stroking a 4.6L engine to 5.0L will yield you 8.6% more power, so a 300HP car will go to about 326HP... a lot of money & work for not much gain, you would probably be looking at $5k in parts and labor.
The cheapest option is the tune, which you have already done.
next up would be cams or long tubes which you could probably get about 20 hp out of each. betond that for the typical bolt-ons you are looking at diminishing returns.
So you're at the major power adder point.
Nitrous is the cheapest but you have to pay to get the bottles filled whenever you want the power, maybe OK if just using it for occasional drag racing, but beyond that you will probably be left wanting.
there are cheap turbo kits out there, but almost everyone I know that has gone with a CHEAP turbo kit has either abandoned it or paid much more getting it to work reliably.
centrifugal superchargers (paxton, procharger, vortech, etc.) are the next in line and are good, but generally start kicking in at higher RPM levels, the power curve is a straight diagonal line up to redline.
Your positive displacement superchargers (whipple, edelbrock, kenne belle, roush) will give you a kick in the pants when you mash the go pedal, giving you a steep horsepower curve up and then leveling off toward the high end.
High quality turbo kits will run in the same price range as the positive displacement superchargers but will operate more like the centrifugals as far as power delivery.
as long as you keep the RWHP power level in the 450-500 range, you should not need to build the engine as long as the tune is safe.

How much power do you want, and how much are you willing to spend?

your fianances will determine what you can get. Turning your 4.6 into a 5.0 will be expensive. You can save a lot if you do it yourself but expect to spend 8 to 10k. tack on a supercharger of atleast 5 to 8k and you will find that adding horse power is expensive. As was already stated you could do the mild yet expensive cams and headers. Personally Id skip that and go to a supercharger

The way I see it you have two options:

1. Do simple N/A bolt-ons like I have and settle for around 310rwhp.
2. Add a supercharger kit e.g. Edelbrock E-Force, Roush R2300, DOB GT450 but stick to a maximum of about 450rwhp on an internally stock engine.
