Also, remember when doing injector size calculation that LS motors run fuel pressure at 58 psi.
Flexfuel injectors are actually larger...flow more lbs (like 34lbs vs. 27 lbs +/-)....than the regular fuel injectors to allow for the E-85. Unless you WAY oversize an injector, it won't affect idle, etc. much, if at all if tuned correctly.
Larger than the 42 lb ones you are using? Should make for a cheap junkyard solution if you needed more than 42 lb ones on just gas?

FWIW I'm using an rpm perf for my turbo 383 and the distribution is beautiful according to my plugs. I use a sheet metal elbow and 5.0 TB. I have a friend who has also had the best luck with distribution and mpg with a DP on his turbo 340. My take away is use whatever intake you would use based on the goals for the car with a carb and not sweat the efi. Other people may have had a different experience.
I really have no experience to refute that experience with....so I don't know. I think all the stock high performance type intakes all tend to have long somewhat equal length runners...but most TBI style intakes tend to be more of a dual plane style...and vacume signal doesn't apply there...so it must work.

Exactly what I was gonna mention, you need to plug the distributor hole anyway, the Ford design does that pretty cleanly...
Is that off of the 4.6 SOHC?

I plan to build a body that plugs the distributor hole, uses the stock shaft/drive gear, and accepts a Jeep CPS. i will just have to cut down the stock shaft at the top. The rest should be super simple. Perhaps use some good bearings in the system instead of bushings.
It looks easy to make on the lathe/Mill, and would look much better than a converted distributor on these conversions.
When I get to that stage, I will post pics. Op good tech! I may start my own thread on my conversion, but will wait till you get farther in yours so as not to detract from each others tech!
I had ideas of doing the same thing using this as the body.

Does anyone have a pictures of a 411 LS1 PCM.
I believe I have one out of a 99 silverado that had a 4.8
Unfortunately there is no tag on it anymore.
Is it supposed to have 2 or 4 connectors?
I believe the 12200411 pcm uses two 80-pin connectors.

That's correct...2 plugs and a '99 4.8 would be a 411 PCM.
And thanks for the injector part numbers....good info!

I thought the same thing when I pulled this while rebuiling a ford 3.0 at work. It even has the same hex drive for the oil pump shaft. Hall effect w/2 pin plug, 5.030" OD shaft.....Might be easier/cleaner to mod one of these than fab something from scratch. Ford 5.0/4.0 and 3.0 pushrod motors all used them.

Any chance this setup would work with stock Gen III Hemi dual plug coils? I am looking at two Edelbrock 500 cfm carbs and the MSD controller currently, at a cost of about $1300. It would be nice to save some $$ and get a good tuneable EFI!

For anyone that might be wanting to do this with drive-by-wire (don't be afraid it's just technology ) I have found (maybe) a supplier that makes 4x cam sensors in a dizzy for chevy's. Now, I don't yet know if they will sell them separate from their kit they offer but if they do it would be an easy way to adapt to 4x. If they won't sell them without buying a kit I am going to venture into modifying a 1x reluctor like Quicksilver440 used into creating a 4x signal that can be picked up by the sensor. Does anyone know if there are any production engines that use a 4x reluctor and sensor that would fit in a Chrysler dist.?
