Theoretically (albiet time consuming) you could collect the MPG from readings from people(via the website), the EPA MPG ratings for their vehicles(from fueleconomy.gov) and then calculate it.

That one is now retired, but I'm building another conversion and that one will also be listed here under its original gasoline, "as-built" condition using the current EPA value.

Eh, that's stupid. If there is an EPA rating for the engine you're putting in, then I'd take the EPA rating from the car it was once in and use that as my basis for calculation. I mean sure things can get sticky when you're taking a diesel engine from a really unaerodynamic vehicle and putting it in a slow aerodynamic vehicle where you don't know where to attribute what to what but aside from that, if you're putting an engine from a car that clearly gets better mileage into your car which gets less mileage, then it is only fair to use the rating from which you stole the engine from. i.e. if I take an engine from a Civic VX and put it into a Civic Sedan, I should use the VX rating when calculating my MPG rating.
I'd say the whole point of any of these modifications is that we end up with vehicles on the whole with better, not worse mileage. IMO if you're going to swap in an engine, take an engine that was dumped out by its owner (unwanted) opposed to taking an engine from a perfectly working and efficient car and putting it into your less efficient.
