It'll be good to know the current mileage with the twin carbs.

I bet...These carbs are over jetted AND Robert can't keep his foot out of the throttle! As such, any mileage ratings are questionable at this time.
He probably needs to simmer down on the throttle and avoid neck injuries.

For the A/C compressor and power steering pump brackets, what was decision for making them out of steel instead of milled aluminum?
I don't know about such things, so maybe the answer is obvious. I would think cost would be lower on the steel brackets (and one fab source) and easier to prototype. A little weight savings would be the advantage of the aluminum brackets, but dissimilar metals may be a factor.

I know this has nothing to do with Robert's conversion...
But this article is pretty informative:

The more I read about LS and Cummins engine swaps and all the various fabrications needed, I'm leaning more and more toward this setup as it seems like the right thing for me. Not putting those conversions down, just not for me. The quickness of the LS is appealing but realistically, I never bought my 110 thinking it would be a race car.
If this 292 conversion works out to be all that it looks like it will be, count me in to covert from the 3.5 to this 292. All I'm looking for is being able to quickly get out on the highway and be able to maintain speed. On back roads at inclines/hills, I'm looking to not act like a loaded 18 wheeler...speed up going down the hill so I can hopefully make up the next incline and staying close to a decent speed. Being a bit of a "sleeper" truck for performance and surprising other drivers would be cool too but like I said, for me I'm not looking for a race car.
Having the extra room under the bonnet is a huge plus too. Ease of maintenance and room to add power steering and AC in the future is also appealing.
Can't wait to see more about this...who knows, maybe I'll be one of the early adopters!!! I enjoy working on and updating my 110 so this is right up my alley.

Agreed. The price difference between the two is day and night.
There's a lot of us waiting for this kit to come out.

I bet its closer than you think after factoring in a $1500 transmission and $1000 EFI kit.

Realistically, whatever the new motor is, LS or the 292, it's probably either going to be an EFI or 4 barrel carb anyway so it's a wash.
Aren't most putting a new trans in with the LS too? Not sure but that's what I keep reading.
Thing that's attractive to me is the easy of dropping it in and the cost of the motor.

You need neither. The whole point is it is designed to work with the stock gearbox. Straight bolt in job. EFI is just a nice to have.
You MUST use a new gearbox with the LS. And upgrade the axles, and, and, and, and....

I doubt that. You are sitting at $10-12k just in parts for a basic LS swap. I highly doubt the 292 kit is going to cost anywhere close to $8k(plus $2k for a performance 292, $1k efi, $1.5k trans) to make it close in price.
I also missed the part where you need a new transmission.

My Rover V8 is fine today, but this is looking like a great alternative.
Yes I would change to a stick shift (have to have one in the family). My only disagreement with RD in his spec in Post 1, is the TC ratio
Given the Max hp/torque revs I'm preferring the 1.003 ratio over the 1.22. 1950rpm v 2236 @70mph

True. But you can run carbs and forget the EFI system... And from what I'm hearing they are a PITA to tune.
Also, a LS conversion is over $10k

My bad, I read the bit on the first post about the Ashcroft short R380 as a requirement, didn't realize that was an option.
