Oops, I noticed I didn't scale the Ford quite perfectly and the editing time expired, it's actually an even closer match than I thought:

They are actually a very good match.
They don't quite match below 3000rpm on the Chevy which is 3500 rpm on the Ford, but I don't think that's relevant for a racing application -- if your revs have dropped that low, you're in the wrong gear!
Of course, these are the 500hp road models and it would change a bit when they tuned up to 600 hp -- but matching Coyote and LS engines is what Supercars are trying to do anyway. You've got the flexibility of variable cam timing on the Ford engine after all, so you can use that to adjust cam angles at certain rpm (even to detune the Ford in places) to try to get it as close as possible.
