For your consideration. We pulled this outta the junk pile and built it.
+.030" 383, stock forged crank, stock rods & bolts, cast pistons flycut with die grinder, 8:1 compression.
Ported 906 heads.
eBay used Crane Gold Race 1.5 rockers.
Used cup and ball pushrods recut to length.
Hughs solid flat tappet, 242/248, .543"/.563"
Edelbrock Victor 383 intake.
The old trusty 950 cfm 4150 Quick Fuel.
RPM.......LB-FT........HP
3600......348.........239
4000......341.........260
4500......369.........316
5000......371.........354
5500......412.........432
5600......426*.......454
6000......414.........473
6500......398.........493
6600......401.........504*
Did it get installed in anything, if so what did it run and what did it weigh ???
Nope, we built it to test the heads and some intake manifolds, the engine got split up.
The short block got a hydraulic roller (the last one I will EVER use) and went into the grandson's 4x4 pickup.
The heads went onto the 451 of the "WarRock Warlock" pickup (big, black and 40" tires). The last time at MATS it ran 12.90 at 100ert-n-sumthin. He is still tryin' to figure out how hard to launch it and how to get it to hook up.

For a 383 stroker using 440 parts, can I use the same pistons or do I need stroker pistons with shorter skirts? Im just wondering the cost to build a budget stroker with parts I may already have vs a stock 383 build. Unlike other motors I have built before, I would finally like to succeed in a budget build for once and not go broke. My goal is to get the Charger running this year. It has sat for the last decade since I got it. Time to finally do something with it. Once done I can figure out what to do about the body.
You are correct that you'll need shorter skirt pistons. And since you're talking about a 383/432 type stroker, you'll be looking to forged pistons from Ross or Diamond which will make for not a budget build.

what he said , the 383 is the red headed stepchild of big block mopars .
I tried for 3 years to sell a set of diamond .030 pistons for a 383 based stroker , at a loss as I usually do some people wanted me to give them the pistons for free and pay the shipping ... moparts is full of the cheapest [censored] in the universe ... someone finally realized what a smoking deal they were and bought them a month or so ago.
Diamond makes a piston that will work with the stock 383 rods, you can use a 440 crank and have the mains and counterweights cut to fit the 383 block, you'll have to buy $$ pistons.
Another deal was the 383 that was being sold in the parts section, the pistons and the rods in the ad cost me originally a lot more than what I sold them to him , I bought them back because I realized what a good deal they were. Speed pro pistons weight matched, refurbed stock rods with wavelock bolts and a set of plasma moly ductile rings . Dan at Performance Only did the rods , they were a work of art on a set of rods I picked thru 3 or 4 sets to get the best ones.

i have a 400 in my dart which is just a 383 with a bigger bore. i think it runs really good, here is the combo-
KB hyper pistons @ 0 deck
eddy heads 84cc milled to 74cc
comp cams roller rockers
eddy performer RPM intake
holley 750 street hp
comp cams XE274 cam
stock forged crank from a 383
stock rods/oil pan
headers and 2.5: duals w/x-pipe
355 gears w/locker
this would probably make a nice dependable street build.

Did you have to notch the top of the bores for those size valves?
One doesn't have to , but notching the bore on the exhaust side would be a good idea, the Max wedge had 1.88 exh valves and they notched the bore.
i used to notch both sides on the 4.25 bore to match the combustion chamber.

back in the day i had a '68 383 4spd road runner with 4.10 gears. with a dp4b intake, crower 201hj cam (228@.050-.480 lift, no longer available), hooker 1 3/4 headers, 780 holley, probably 3850lbs with me in it, stock pistons and heads; it would tickle 12.90's. drove it everyday, it was the only car i had. with today's modern heads and cam profiles this should be easy to duplicate. just one biggie to keep in mind, DON'T OVERCAM! evrytime i went to more cam the car slowed down.

Well just out of curiosity, I may just price out what it would cost to "stroke it". But even if I just did a nice standard rebuild with a few hand picked parts, I could still be happy. Anything to get the beast back on the street would be good. I'll price it both ways, but like most of us I always want a bit more. I'd like to stay with stock heads and valve train to save money, as long as they are in good shape.
then the cheapest route is the just do a 440 , you can stroke out the 383 , spend the $$$ and still have nothing better than a stock 440 because of your head choice .

the OP said he wanted to keep his 383
theres an article in this months Mopar Muscle-a simple 906 headed 383 with a mild Comp Cam (~.500) a dual plane intake and a 750 carb and a good tuning will put a 383 into the 425 HP/500 ft/lbs neighborhood. Thats plenty for a fun street driven musclecar. $3K more or less depending on your local machine shop.
It doesnt take a lot of high dollar parts to get power out of a big block.

I'll have to check that one out , I'm doing an on the cheap rebuild of a 383 for a friends Road Runner and that may be the ticket for what he wants .

I wasnt singling you out Johnny 
My local machine shop just did my Pontiac 400-$2200 covered a sonic check, .030 overbore, balancing and cylinder head cleanup and they even assembled it for me. Theres no reason a 383 like the one in MM couldnt be done for under $3K 
I need to move where labor is cheaper, I'm not sure what this one is going to cost but the budget is 3k.
I also have a stock bore 383 HP that I'm going to dingle ball hone and put in fresh rings and bearings type of rebuild to throw in my superbee for now .
