hey ive got a 350 2 bbl. Im debating on making it a 383 stroker. I dont know that much about cars yet but i know im gonna need a nice 4bbl, an intake, maybe a cam, some nice exhaust and a 383 conversion kit. Is this a good idea to make it a 383? also how much hp can i get out of a 383? does making it a 383 make it harder to maintain? and also, how much will all those items cost me approx.? thanks

You can make that into a 383 no problem.
But first, what kind of car is this motor going in? You might not need a 383.

All of your questions would need several books to thoroughly explain but I'll take a crack at covering some of them...
"Converting," as you put it, a 350 to a 383 involves lengthening the stroke approximately .270 in. This is done most commonly by changing cranks to one with the same rod bearing, main bearing, snout sizes, etecetera but simply has a "longer arm." This needs to be compensated for in the piston by raising the wristpin location in relation to the piston crown as to not push the piston through the cylinder head at TDC.
Is it a good idea? In most cases, yes. There is a definite gain in midrange and low-end power simply because there is a larger cylinder to feed and if the induction can feed it to any degree of decency there will be gains - top-end gains may be slightly diminished with poor OE-type cast heads with small valves that may not have sufficient area to feed a larger engine at high rpm.
Maintenance is really not affected - some argue that the longer stroke creates more friction and more rod angularity which can lead to decreased bore/ring life but I believe this is negligible - especially in the case of a mild street engine. Some advocate the use of 6" rods to restore the factory geometry, which is guess is believed to be a satisfactory amount.

360-580 hp ...they are all diff engine combos...
pump gas ...easy 400-460 hp...
secret is in the choice of heads and a HYD roller camshaft with a MODERN profile..
AFR 195s and 224/230 @.050...EASY liveable motor..
