The add on alumimun heads and intake to get the power he wants kills any stealth look he may be after. A 383 block will cost him as much as the 440 so again why go small? I've done a bunch of both and the 383 won't last as long as the 440 at the same horse power.

what car is the engine going into. The 383 is sometimes easier to fit in the A-body cars, but there are more parts avaliable for the 440 (mainly bearings and intakes.)
I think alot will come down to cost. The 440 source heads are nice, but I think the valve springs will only be good for a hydraulic flat tappet can with around mid 230's @ 0.050" duration (I think the Performer RPMs are about the same?)
If you use the 383, I would go with a stroker kit.
The 440 could be done with the stock crank.
If buying a 440 is going to cost $$$, and you plan to replace the pistons and rods anyhow, then the difference in cost of stroking the 383 would be the cost of the crank - what a 440 block would cost, and the 383 would have more displacement than a 440. On the other hand if you have a 440 or can get one cheap the cost to build either is about the same.

Which bang for the buck is better to build your own or buy a new complete carb to pan from one of the performance shops such as indy, huges performance doug herbert eagle or any the other ones has anyone bought one from any of these shops or now of any other repitable 440 builders that i should consider to look towards if new is the road to take. Thank you for all the input its needed 
Sorry, I don't know too much about what is avaliable as a pre-assembled crate engine, or what they are selling for. If you have the tools and ability to check and assemble the engine than you should be able to save some money doing it yourself. On the other hand the crate engine builders should have the combination pretty well dialed in, and they should provide some warrenty against defects in workmenship. For example, the engine should not leak, the fastners should be torqued correctly, rings gaped and installed correctly, etc.)
If you have links to crate engines you are considering post them. I would be interested in what they offer and what they cost?

looking to make 550 horsepower on street car question is to go with 383 or 440? 440 SOURCE has a stoker kit for 383 that makes the 383>>496 (4.250' with the aluminum heads stealth Is that bad for the 383 anyone ever go with that? easier to get hp out the 440 Is the 383 a waste of time to build? Or would it be cheaper and better to go with the 440. Not looking for the cheapest necessarily but relighable. Or would it better to buy a new 440 from pan to carb if so who has the best deals complete 440s. found This Doug Herbert Big Block MOPAR 520 produces over 600 Horsepower and is assembled using the highest quality components at a reasonable price.$ 8.995 any suggestions and or advice will be greatly appreciated thank you for reading 
I saw that add too. Hard to beat that price. I'm guessing you might be able to do it cheaper but you'd have to do a lot of the work yourself. If you have both blocks I'd use the 440 and stuff a stroker kit in it w/ a set of alumnium heads on. 500ci + aluminum heads + a decent cam + intake and the right carb should produce 550 pretty easy.

You can get an easy 500 out of a 440 without even stroking it. You may want to consider this to save somne $. Believe me 500 is plenty of HP.
 Plenty of people with 500hp 440's on here running 11's in the quarter.
