Oh wow! Lots of interest in the MS build.
Here is a link to the build start to finish for those super interested, I detailed the build fairly well to try and make it so people were not so scared of it.
http://www.dodgecharger.com/forum/index.php/topic,99432.0.html
Basic rundown of parts is:
*deep breath*
440, .30 over 10:1 E-heads, Comp XS-282 Solid
MS3X Controller
LS Individual coils (LQ9 off a 2003 Yukon)
32 lb-hr injectors out of a ford raptor 6.2
VR sensor out of a ford rustang
TPS, IACV, MAT, and MAF sensors are off of a 2003 Saturn
CPS is adapted down with a custom bushing I made to use a 2003 Jeep 4.0 Cam Sensor
EGO Correction is an AEM wideband
Fuel system is a Walbro 255 to some cheep frozen boost.com -8 lines and fittings
i just read that entire build 3 times. the worst part for me is gonna be the cam sensor since mines a b block

I was looking into the self learning EFI systems and from what I've found is they dont like cams with over 250 deg of duration. My 440 has the old MP 284/484 cam, self learning EFI isnt goin to like that.

284 is the Advertised Duration for the MP cam... The EFI system manufactures are looking for duration at .050, which in your case would be 241, so your cam is fine.
With the MegaSquirt system you don't need to use the manifold air pressure as an input parameter for the naturally aspirated engine control, thus you can use whatever long duration cam you like.
You can set up the MegaSquirt to just use the RPM value and Throttle Position Sensor value as inputs for the injection and ignition control (plus of course air temp, engine temp, ambient air pressure etc.). This is the way I'm going to use it in my stroker build, and that type of control (called Alpha-N) already works very well in my high performance Ducati motorcycle.

Nice framing of the engine shot  I like.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I've had the EZ EFI system up and running for a few years now - no problems - best thing I did was get a rock valley gas tank with the pump in the tank.
I have a "new in the box" tank that I was thinking of converting over, but I still don't know which would be the cheaper option at the moment, buying one or making one.
Nice setup by the way! Love the dual quads!

A friend of mine put an EZ EFI kit on an LS powered mustang. He's pretty happy with it. I am not sure how good his setup on his carburator was but it went faster with the EFI. He had one problem during setup and initial drive but it was something he misread in the instructions. Tech support got him lined out. The car runs 11.teens @120ish.

That looks like a nice pump, but, no E-85 compatibility, and can in be mounted in the future "in tank"?
I was also surprised with a #10 outlet they suggest only a #6 fuel regulator return, I wonder if regulator manufactures agree?

I believe they mean at least a #6 (minimum)
For whatever reason, a lot of folks will run a smaller return than their supply.

From Jim at Weldon Racing...

Yes it can, if you really need to, but I don’t recommend it just from the fact that the pump is quiet and pulls fuel without a problem. There are some out there that believe if you drop the pump in the tank, it’ll quiet it down and keep it cool…… not as much as you think, if you start out with a louder fuel pump it’ll still be loud.
