im not sure what stroker kits are on fleabay but i dont know if i would trust them. You have alot of reschearing to do if you want to go that route. I would start with all the bolt-on's first. Then go from there. You need all the supporting mods first before you dive into a project like that.
You need to take a step back, do a little more research and plan your project accordingly.
You do not buy a "kit" on ebay and expect to just throw it in.
First, you don't need a stoker to run a procharger. You can run 7psi on a
stock bottom end or build(/buy) something with less compression to handle even more pressure.
Second, you're going to need cash and time ... and a lot of it.
Either project (stroker or blower) will run into the thousands very quickly.
How fast is your friend's car? Maybe we can narrow down your goals/options a little here.

He might have a very powerful, well built engine now... but don't forget that when it was stock, its was an ugly, 15 second, 230hp sled. Thought I'd throw that in there, always gives me a good laugh.
^ Exactly. Over $27,000 in my build. If you want to build a 383 and procharge it..you better expect to build up the rest of the driveline, suspension, etc.
If you think you can build this thing on the quick and cheap, you're in WAY over your head. Or you'll do it and it will blow up immediately.

What everyone else said, don't even think about the stuff you just said cause it will never happen unless you have at LEAST 10-15K. And even then it sounds like you don't know what you are doing so it probably wouldnt last very long. Sad but true.

a procharged 383 is not cheap, you're talking about $6-8k right there and that's just for a procharger setup, crank, rods, pistons, bearings, rings, and LITERALLY nothing else. Factor in atleast another $1000-1300 or so for machine work and assembly, atleast $500-600 for fuel injectors/pump, $700+ for exhaust, $400+ for a tune, and it keeps going. Right there is around $10k in parts and you still have stock heads, stock cam, stock transmission, stock rear end, etc. and assuming you do the installation of parts yourself.

Verdad Gallardo If you need to rebuild it I am sure a nicely built 355 with a le2 set up would do. But even that will not be cheap. Check out this site and talk to Lloyd if your serious about building your car http://elliottsportworks.com/home/?page_id=51
Well the old 5.0s are very light in weight and he did say his friend has a 408 stroker which is using a Windsor or Cleveland block. I've seen some of the common builds for these things and the usually make 525 -550 hp at the flywheel na and way more if he's boosted or on spray. So I'd imagine the car should be pretty quick, but nothing a built 383 or 355 with good heads and cam should be able to handle but as everyone else has stated it's gonna cost big bucks. How many miles on your current engine, if you are near or over 140K I would rebuild it. Get good light forged pistons and 6" Scat or Eagle H beam rods, 4340 forged crank or re-use your stock crank, get LE or AI to port n polish your stock heads and intake and a custom cam to match, long tube headers, cai, bigger injectors, a tune and a 150 shot and see if your stang friend can keep up. Also get a converter since you have an A4.
If you dont have money to go big..start off with bolt-on's,gears and a nitrous kit see how you like that. I notice this is your first car so take your time,do alot of research...Also what 408 stroker mustang you speak of is it red, tuned by RET?

And what shot are you talking about? Its like asking what the top speed is on a Lexus. They all have different top speeds. depends honestly.
some people have sprayed regularily on 100,000+ mile motors with no problems while others have not been so lucky. good tune, good plugs, regulated bottle pressure, and keeping detonation generally in check are all you can really do and hope for the best.
as far as what route to take whether it be h/c, n2o, supercharger, turbo, etc. all have their strong points and weaknesses. ultimately its up to what the owner wants, not what the "best" single path that everyone should take is, because that answer is not as universal as some might make it seem to be.
