It should have at least 100 hours on it, simulating 4000 miles (per the testing standard, and that assumes it was only used for one test). So it is "broken in" but still "very new".As Willie N would say: "On the road again..."
If I understand correctly, you should be treating the engine as if it was just assembled or re-built. The original use was for limited hours, so the thing may not even be broken in yet.
I figured you'd like the added power those tiny 300ccs provide, and the EFI makes it all run so much more efficiently than the carb. You should get in the high 20's in US mpg terms. Km/l or Km/IG I dunno. Do they still use 'Imperial Gallons' in Canada or is everything metric? I have not been in a long time, but do remember the volume was larger.

Do you have any thoughts on the 140PSI compression?
I know the standard is "as long as they're all above 100, and within 10% of each other, it's fine" and 140 is healthy but seems low. I'm wondering if I should have tried putting the cam another tooth or two forward and seeing if it got better. It runs very well and has great power though.
We use litres per 100km, and it's done that way because a litre is so small compared to a US gallon that it gives better accuracy and friendlier numbers (not crazy decimal places). However I generally convert units and check my numbers in US MPG.
The old engine with poorly tuned carb was doing 14-16 US MPG city driving, I'm hoping to see a consistent 20+ if driven reasonably. If you think I'll see upper 20s that's even better.
edit:
responding to the earlier remark about the O2, it's a junkyard manifold and I put a brand new NTK O2 in it.
As for sensors/electronics in general:
The TPS came on the engine; I've tested it with an analog ohmmeter to make sure it's flawless.
ECT and ACT(IAT) are junkyard parts from my stash which are known to work.
EVP (EGR Valve Position) is a junkyard part on a junkyard valve.
IAC valve is a junkyard part.
MAF is a junkyard part. I have two junkyard MAFs. This is my first Mass Air vehicle so it's somewhat new to me.
ICM came on the engine.
CPS came on the engine; I've actually swapped it for a junkyard Wells aftermarket replacement which is working, so I have a spare in the form of the working original Ford one.
