Car keeps stalling in gear? Causes and how to fix it?

[WHITE AND RED 69]

I've got an issue that i'm fighting right now and am stumped. Car starts, idles, and revs perfectly fine in park but soon as I try to take it around the block and give it any gas it starts to stall. It stays running if I back off the throttle but if I try to give it any gas it starts to stall again. Can't get it above 1700 RPMs without it starting to die. No backfiring or any other symptoms.  

I thought maybe a bad coil so I swapped in a new one with no change. Swapped in my old distributor just to check it and no change. I have pulled all the fuel lines and filter and they are clean with no obstructions. Throttle body has the correct fuel pressure and is getting gas. I can hear the fuel pump so I know that's working. And I have spark so I'm out of ideas what it could be. Checked for vacuum leaks and couldn't see anything.

Car ran perfectly a week ago and the only thing I changed was an oil and transmission fluid. EFI isn't giving me any pump or injector codes and everything seems right?  

Setup is:
440 with iron heads
727 trans
MSD 6AL ignition box and coil
Firecore distributor and wires
Fitech EFI throttle body
performer RPM intake
electric fuel pump in the tank

Anyone have any ideas on what might be the problem?

Dose the FITech have a set up module that can show you the A/F ratio as you drive? If so see what your fuel flow dose at 1700 rpm.  

My first thought was the distributor, but you swapped that out.

My car is doing almost the same thing right now. I looked at the glass fuel filter housing and it doesn't seem to be "full" when running. Just barely dribbling through. I'm looking at changing the fuel pump for safe measure.

Definitely check fuel pressure while running under load if possible.

Dose the FITech have a MAP sensor? that is what it sounds like.

That's my suggestion as well: checking fuel pressure under load...

Sure sounds like it's starving for fuel, maybe something going on with the throttle body or maybe the fuel filter is stopped up. May call fi tech and see what Ken may suggest you to check...

mine had the same problem although 318 motor ,as soon as you put it in gear (reverse , drive etc ) it stalled.New motor, new transmission ,new electronic ignition ...everything

new coil was crook replaced the coil , 
worth a try

He already swapped coils...

Does the car has a throttle postion sensor with the electronic fuel injection? Could be getting a bad reading at partial throttle

you sure you don't have a vacuum leak,
or did you sort out those headlight doors not working ,
that's enough a vac leak to be painful

All the sensors on the EFI are working as they should. If they fail the computer will throw a code.

I did get them working but I am suspecting there is another leak. I didn't have time over the weekend to mess with it but I'm going to pull the intake and change the gaskets just to be sure.
