I thought the above car interesting. In particular the alloy head, does an alloy head confer many benefits?  Who made the heads and if only three, were they not very successful?

they saved significant weight

A flat configuration ---horizontal rods, but engine is vertical. Someone who wrote the add has verbal diarrhea, plagiarism at its best (revealing utter crap)

I do believe that AC built a flat six but its not in this car.

Surprised I don't see Subaru in engine bay. Lightbulb moment-,may be a good aftermarket swap or a lexus V8.

I'll add to Robin's weight note, that aluminim alloys also having better heat transfer and with a manufacturing hat on, they are faster to machine.
