Of course go with the 440 if you can get one and want to use it .
That said if you want the car to look STOCK , get a 400 block , put a longer stroke crank in it , you get the cubes but it will LOOK like a 383 to the BLOWHARD with the 440 you just blew into the weeds .

I would side with the 400 crowd. I built my 383 though and am very happy with it. The thing is most guys in the clubs and such simply cruise there cars around anyways. Very few actually drag race them and it can be pretty risky to go out and be recklass on a back road now-a-days, cops don't let anything slide, soccer moms call the police when they even HEAR your car, and insurance for tickets will skyrocket or be dropped all together. Put simply there is little tolerance for that stuff. Bottom line is I've seen 500+ inch, nitroused, gear driven motors driven around like grandma cars with occasional blasts to show off the goods. Yes they are crazy fast but rarely are they used for their intended purpose.
With that being said a muscle car with a powertrain that you can drive anywhere and pull 12-13 seconds in the quarter mile is pretty darn respectable. That is easily done with a built 383 that can look factory. and you do get the benefit of keeping an allready nicely optioned stock roadrunner...well stock.
Personally I love the idea of a stroked 400 though and make it look like a 383. I have a 400 sitting just for that rainy day.
440's are awesome motors, but I think too often 383's are shelved. My 383 keeps up just fine with a couple of the 440 cars here in town. A lot has to do with the whole combo too...gears, gam, carb, etc. I simple gear change can help a lot actually.

There's only going to be ONE numbers matching engine for your car. Store the matching 383, build the 440 and run the "H" out of it without having to worry. If you build the 383 you'll always have that little voice in the back of your head (I have 3 or 4) telling you to ease off the throttle. If you throw a rod through that 383 it's gone, if you throw a rod through the 440 just find another and go at it again.

there he is.... the 400 route would be fun too. It's all going to cost about the same if you are starting form scratch. Look around and see if you can find a good bottom end and go form there

Rebuild the original 383. You are 18.
You'll change your mind a lot going forward. That's A-ok. Sell the car as a matching numbers unit at some point and then buy a 440 toy.
The world does not need another hacked out 383 car stuffed with a 440.

I've got a '71 RR with a 383 and 44000 orig Miles. I rebuilt the #s 383 and stroked it to 432. With stock heads and only a intake manifold change, it made 430 horsepower and 470 torque.
The only thing I would change is using the 4.250" stroke crank and go for 496 cubes. All sleeper.

my cuda is a 383. it's going to get a built 440, and I'm gonna paint it blue, and put a stock air cleaner on it with a "383 2bbl" decal.
half the "mopar guys" would have a hard time telling it's an RB block and not a B Block, let alone all the chevy and ford guys.
I had my cuda for 2 years before I could visually identify the difference of a 383 to a 440 by just glancing in the engine bay.

The car in the garage is my father's 67' Dart GTS. Has 440 making 650hp, 32in big meats on the back, the works. That's my inheritance once he's long gone, at least thats what he told me. I've been told to use a 400 engine cause its identical to the 383. But I might just rebuild the #'s motor since it will be cheaper. What I'll do is once the car is finished, I'll begin building a second motor, and pick a weekend to swap out motors.

The car has a lot of value because of the odd options that make this bird very unique. Yes I know its not 1 of the 55 hemis or a 440+6 car, but you gotta think for a kid my age this isn't a bad find. Here's some of the options the car has in it, just to give you guys a rough idea of what I'm working with here. -Born June 10, 1971 -Taken off the road in 1977 and garaged ever since -383 High perf. motor (4 barrel) (100,017 miles) -4 speed pistol grip -Shifter console, buckets, black interior -3:23 sure grip posi (8 3/4) -Air Conditioning -Manual brakes (drum) with power steering -Origional paint: Curious yellow -Black Canopy Vinyl Top with Black strobe stripe -Origional Dictaphone cassette recorder -Factory Hood racing pins -Factory exhaust (can be re-used) -100% rust free -Has a Clock instead of RPM gauge -Amber turn signal lenses Removed the vinyl top and began body work so she's in solid primer. Ran all possible numbers on this car and it is an all factory car, minus the carb and radiator.

WOW!
That is a great find man.
Seeing these I definately would lean to keeping it as stock appearing as possible. Either a stroked 400 or build the 383 if it were me.
As you said you allready got your toys for going crazy fast. A built 383 4 speed will be very fun in this car and you can restore it, park it at a show and win some stuff too.

 except id do a stroker 400. more cubes ans you cant tell the differeance between a 383 and a 400.
i have a bahama yellow 71 roadrunner. i bought a 71 bahama yellow roadrunner as a parts car about 5 years ago to help put our 72 satellite together. the parts car only had a rusted up ashortblock in it and i aways thought it was a 383, one day i started looking at it and it turned out to be a 400 with no vin on it. im pretty sure it was a warrenty motor. i figured it was its destiny to be in a bahama yellow 71 roadrunner so i biult a 452 inch motor out of it and put it in my roadrunner when my 383 ate the cam. my numbers matching 383 is now safe and sound.

It may have value , but you aren't going to retire off the sale of it anytime soon .
oddball options , or lack of don't really add value .
What that car has going for it is the COLOR , the 4 speed with air conditioning and it's original engine .

Nice car, but going to cost you a chunk to restore. I wopul suggest that going with the 383 may not be the gutsy way to go but it will cost you less to simply have what you got rebuilt.

I have already given it the thought that it would possibly be cheaper to rebuild the factory motor, put in a good cam, and hone or bore out the hi-po manifolds and factory intake to allow for better air flow. Will also port and polish the heads (2.08int., 1.74exh.). Does anyone know if this is the '906' head and if they are good heads?
I want to build this motor up and run real nicely but still have the ability to put a ricer in its place on a rare occasion. Anyone have suggestions for getting a HP 383 to make 400+hp using the "stock" appearing parts such as the intake?
