Incidentally, I took the time to look up Paul Elios answer from the July 2 AMA and here it is.

Our casting supplier is Nemak. The process for the engine build is that Comau employees will build the Elio engines on the equipment we purchased from Comau, with Elio employees watching. Then we will flip-flop. Elio employees will build our engines with Comau employees watching, and eventually we will wave them away and say "we've got it from here."
I believe you are correct that the 1,500 employee estimate does not include the engine assembly. That is the vehicle assembly only."

Hope that is helpful
Sorry, I should have included Rog Wild's question so here it is.

Mr. Elio; ref. IAV ENGINES - WHO and WHERE will the Parts for the 500-1,000 Engines (per day) be 'CAST' in order to keep the assembly line running? How will the “Elio Motors Engine Manufacturing Facility” and the regular 'Vehicle Assembly Plant', be able to function at that capacity (one engine/ vehicle per minute) with only 1,200 employees, when the Ford's Brook Park Plant (with 1,200 experienced workers, and a 1,200.000 sq. ft facility) currently only produces 50 EcoBoost engines per hour, running 24/7...... and they are ALL devoted to just making ENGINES!".............
