Can't believe they'd offer the 392 in a Wrangler/Gladiator when it hasn't been offered in the Ram 1500 yet. Besides, didn't FCA already publicly state that although the HC motor technically fits, there will never be a HC Wrangler/Gladiator because it's too tight for their crash test/serviceability requirements? Can't imagine the 392 would be much different in that respect.
But hey, FCA has never been known to do the 'normal' thing, so who knows!
