I have not noticed that the gas mileage is much different. I did notice that the first few times out on the big bore my wrist was getting sore- I realized it was because I was having to modulate the throttle at a lower opening which made it sore.
Very easy install. I'm a rookie on motors and it was pretty easy on the LXR. In chassis.
The EFI adjusted with zero issues. I would say it starts far better than before- possibly due to the unshrouding of the valves in the bigger cylinder.
Pretty simple swap on the LXR; probably a little more teardown on the RX3.

Is there a walkthrough somewhere for doing the big bore install? Specifically, I'm concerned with how to set the valve timing when putting the head back on. With no service manual there's just no information available anywhere.
