I think we're all just a little surprised that you're driving it daily and have no ballpark for the mileage its getting.
That's because in the 3 weeks it's been on the road with the self tuning EFI actually tuned, I keep my foot in it constantly and do not have any real numbers for someone who drives it normally. Find myself flooring it and going fast just because I can not because I need too.
Not going to disagree, just old is old.
Which EFI did you end up going with? And why the 292 over the other engines that would bolt in on your adapter? You've got to get some MPG data! If it lands between 12 and 20 mpg, you may already have sold me. The diesel MPG is one of the reasons I went diesel, I'd need to know it isn't all the way back to what it was with the V8.
BTW, can the R380 that I am running have a different output/bell housing swapped in to fit this conversion, or would I just need to also source a new transmission, tunnel, etc...?
I went with the Holly Sniper 2300

Only because the BBD for Jeep CJ hadn't been released yet.
It gets better.
With the BBD, the stock air cleaner fits right on.
We are going to use this EFI on the GM 3 liter 4 cylinder engines we build.

Why this engine?
The 292 has 280 ft lbs of torque at 1,600 RPM, is bullet proof reliable, runs quiet and smooth, is inexpensive, and has over the counter parts support.
The main factor is that everything is so easy to get to and to maintain.
I swapped the $400 craigslist rebuilt 292 engine, for the worn out prototype engine in 5 hours and was driving it.
Hell, I've helped people over the phone who have more hours on a timing belt swap on a TDI.
Well, the 292 has metal timing gears.
Raub called me to report he had his new starter in his TDI after only 4 hrs work.
Changing the 292 starter is a 10 minute job, 15 if you drag it out.
Starter was in stock at the local auto supply for under $50.
Why not a different engine that the adapter will fit?
The adapter will fit the GM 4 cylinder, GM inline 6 Cylinder, Vortec V6, and SB V8.
Personally I stay away from the V6/V8 engines simply because I don't know much about them, nor do I like the configuration with 2 exhaust manifolds and all the accessories bolt on in a clustered compact space that takes twice as long to work on.
The inline 6 is in there with 1 set of manifolds, 1 down pipe, and everything within reach. It could not be simpler or more easy to work on.
Mileage?
I am NOT getting 30 MPG and have not estimated for fear of putting out false figures.
Everything I write here I actually believe and really don't want to come across as a salesman wearing a plaid sports jacket that is selling used cars.
I can tell you it gets better gas mileage than our Disco I got which is not saying a whole lot.
I can also repeat what you said, that regular gas is 40 to 60 cents cheaper that diesel fuel.
This is a big offset on diesel economy.
Since diesel cost so much more than it damn well better provide some better economy.
But, we only got 20 to 23 with our 300TDI.
If you're running a long belhousing R380, Ashcroft in UK usually has what is needed to fit a stumpy belhousing and first motion shaft.
