What to ask an engine builder selling a supercharged coyote crate engine?

[MikeFromPerth]

hi all

i recently came to hear of an engine builder/workshop over here in Australia who had a couple of Coyote crate engines for sale (one with a ford racing 2.3L supercharger) with wiring loom & PCM. i asked for some details, mentioning that i might be interested in putting such an engine (preferably a supercharged one) into a FFR cobra kit, and here is the answer i received:

Both engines are 2011 coyotes. They were purchased for a project that changed direction. The engine and supercharger kit came from Ford racing. One engine has been used for Dyno mapping and the other was assembled to be used as a mock up during the build of the car. The unused one is all together and they dynoed engine has the supercharger removed. Each engine has the ford racing PCM and installation kit. The throttle pedal is missing off the dynoed engine.
It should be possible to get them through the ICV emissions with a couple of xr6 turbo cats of GT falcon cats. The noise is just a case of fitting large enough mufflers.

For non-Australians reading this, ICV means Individually Constructed Vehicle and refers to the road registration rules (quite strict emissions and noise rules, etc etc) for kit cars over here. So I'm kind of interested but to be honest, i'm not a crate engine expert by a LONG shot and would love to hear from everyone here what questions you think i should ask the engine workshop in order to be sure what's really for sale here. Stuff like:

1. photos please! this could answer a lot of questions.
2. Dyno results
3. which exact supercharger kit is it? (and does it include intercooler/all the plumbing/etc). Perhaps it's the ford racing 2.3L whipple one for 2011 mustangs...
4. What does it come with exactly? Alternator? Water pump? etc?
5. is the engine an "aluminator XS" or "aluminator SC" or what? if my understanding is right, the SC is the lower compression ratio/stronger bottom end version, suitable for forced induction. Whereas the XS is still high CR (11.0:1 or so) but has a strengthened bottom end.
6. is the variable valve timing still active with the tune and supercharger?

so... what else should i ask?? what would you ask if you were in the market for such an engine?

cheers
