ok, so how exactly do they work, do they replace something or some parts in the engine?
A stroker kit changes the displacment of your motor. The main componets in this is the pistons, rods, and crank. Displacment is determined by bore and stroke, this kit gives you a longer stroke. I dont know what kinda of gains you get out of them, you can ask stanger98 he might know.

As of right now I'm not sure what my gains are. But the minimal gains you should receive are 50HP. But at the same time you're weighing down your car with the internals compared to stock. You can definitely feel a difference, the mods in my sig are what got me a 15.1 sec. 0-100 time which is extremely fast for a v6.
Installing a stroker kit is not for the average joe though. They are extremely time consuming and tough to install, but, well worth the gains. If you were to install a stroker + a split port intake manifold, the gains would be phenomenal. That's my plan as we speak.
Oh and by the way, the best stroker kit to buy would be a 4.2 for the mustang. They are the balance between power and engine safety. If you buy a 4.3+ stroker, you'll have the horsepower BUT your cylinder walls will be weakened which could result in catastrophic failure. If you go with a stroker smaller than a 4.2, then you're block will be stronger BUT you'll see less and less gains as you get smaller.
Well im hearing that I should just get an engine overhaul and replace my old parts with better than stoc parts, what do u think about that...?
If you're getting to the 200k miles range then I would say overhaul your motor. It all depends on how the motor's running and everything. If you're really into getting a stroker, then buy the stroker and overhaul the parts that the stroker doesn't replace.

There is nothing wrong with the 4.3L. The 3.8L has such strong cylinder wall rigitity, that it's not a factor for the larger bore even with boost. I wouldn't get worried until you get in the 4.4/4.5 range.
BTW, if you do go with the stroker, make sure you get the long rod version. Engine geometry is an important thing to keep an eye on. The short rods have a tendency to create too much side load on the piston skirts, as well as putting the piston speed a little too high for comfort.
What brand stroker kit did you get? I'm rebuilding a 4.6 right now and I'm about to look into Eagle and their stroker kits.
Do not stroke a 4.6L. I've posted pictures of a stroked mod motor in the 4.6L tech section of one of my customers cars. The problem is the piston spends too much dwell time at BDC, with the piston coming 0.100" out of the bore. The pistons are therefore very unstable, and will wear quickly.
4.2 Stroker. Do you have a v8?? a 4.6 is a v8, so I'm thinking it's a whole different ball game...
Oh, sorry I misread the thread about the name of the stroker kit.

Really? Well I was just starting to look into it because I read in a magazine that Eagle was making stroker kits for modulars now. But I'm looking at buying a guy's 97 4.6 block and building it up to put in my 01.
v6 Stroker Kits?
