I’ve been wondering why the Hellcat is rumoured to be a supercharged 6.2 Liter engine, and not a supercharged 6.4 Liter. Are there some design considerations that would warrant machining a separate block, heads, pistons, etc.? From strictly a manufacturing point of view, it would seem cheaper to slap a supercharger on the 392 and go from there. Maybe this question has been asked before, and it could all be speculation anyway. I am interested in knowing if there are benefits to the 6.2 L from an engineering standpoint.
