Some humorous replies here. First...alot depends upon what YOU want out of your application. I have built both. Many parts are similar. The 375hp versus the 335hp factory rating(which HAS to be pretty accurate because of the way the gov't makes car companies validate their vehicles)...is self explanatory. 40 extra hp to start with just makes it easier(sorry, I live in a 'common sense' world). The 383 is a fine motor, make no mistake about it. It will also rev higher but high revs usually causes more wear on parts.

Well some people have built the bigger bore shorter stroke 340 that could outruns 360s. Mostly that was years ago before 340 parts because scarce. For sometime now parts and alternatives have been developed for 360s to produce more power. Its easier to find, purchase and build 360s than back in the 1970s.
As for the 383, Im simply not a fan of the power it produces. Yes it can produce power if stoked. But otherwise based on dollar for dollar money the 440 will produce more power. And I think this is especially true if your working on a working mans budget.
You have your 383 guys who will vehemently defend them and find the exceptions to the rule examples sure, but some would say they would rather stroke a 400 motor than a 383. This I cant speak about, perhaps someone else could address.

My 440 is making 580 hp & 600 ft tq with only 448 cid.!  Stock crank & rods with KB pistons. Where i get my power is the Indy heads and TTI headers & comp solid lift cam.

doubt the TTI headers give you any advantage over any other brand of header. But I'm with you I have a stock crank/stroke 440 w/ ported Stage VI heads and a comp 588 solid roller making around the same #'s...maybe a tad more.

Reading through this thread I found it consistent with past street racing around my area. Yes, some folks whipped up on a 440 with their 383. Others whipped up on a 383 with their 340. Yep! In many instances, the 440 cleans house too. This would seem to indicate that a well matched engine build, a balanced drive train, a fresh tune-up, and someone who knows how to drive their car can easily break the gap to any advantage 40-to-60 cubic inches can have. But regardless of actual performance, the bragging rights the 440 yields always wins out simply because it’s the biggest passenger car production engine Chrysler built. Bigger is always better, right!?!?

Everyone keeps talking about the bigger HP the 440 makes BUT it's the big TORQUE that moves a car better at a lower rpm that makes a 440 better.
Torque is king on the street. The short stroke 383 is more sensitive to its combo to really work, the 440 is more forgiving.

Nothing like BB low end grunt rumpity rump. From the basement. 440. Otherwise you're just "explaining.
Let's look at this from the TOP(end that is). Nothing like the HI-RPM scream (6000rpm or MORE) going thru the gears. Rev to the stratosphere. That's the 383, baby! Otherwise, YOU'RE just all "TORQUE" (talk)!! And YOUR basement door slams shut AT 5-6000rpm.
A 440 will be two car lengths ahead of the 383 before it even gets to 5000 RPM! 
And LOTS of 440's are pulling strong well past 6000

I know this is just rehashing most of the posts above but for a street bruiser with a set amount of money invested, and an equal build, in the engine the 440 will be the champ EVERY TIME.
EVEN is the engines make the same peak HP (which they wont)
Area under the curve!!!!!!!!!!!!!!!
Contrary to your BELIEFS.... which HAVE some merit, SET COSTS are not part of this equation. YES, the 440 has MORE cubes which gives it a distinct COST advantage. There is less cash outlay and ingenuity to reach 500 hp. The 383, as I stated before, can reach this 500hp level, but due to the less cubes a "bit" more money spent in the right areas can net a VERY capable street/strip motor with great power. If it was a question of money spent or saved (main reason to go with the 440!!) then the 440 definitely GETS the nod. But
a 500hp 383 make cost a little more, but can net you excellent performance. You want to toss 'em
away, good, more for me to build and develop power on!!

Bigger motor + less cash outlay to put in more power = winning strategy!! Nice formula!! But...
sometimes it's not, depends on how well ANY given combo is put together (parts matching and TUNING)!!

60-120 ft past the tree 383's have been known to hit 6000 (or better) rpm (gear depending) and "step out" on 440's in 2nd and 3rd gears. At the 660-1000 ft mark, a "good" lightweight 383 car WILL outleg a 440 car to the finish, driver depending. Your "2-car advantage" has been either eliminated or "switched around" to the 383 car at the finish!!
