Oh wait. That's not necessarily a Hemi right? You got the 6 barrel carb tho right? I haven't got a total handle on all the technical jargon but like em just the same. Hope you're enjoying the whip on this fine day 
It is just a straight 4 barrel. The six barrel is about a $3,000 upgrade. With the Shaker, you can't see the carb anyway, so to me not worth the cost or the hassle keeping them tuned. If I remember, you do add about 15 more HP with the six barrel though.
And Lowend1 explained the terminology perfectly. Like the 6 barrel option names being different, color names were different between the 'cuda and Challenger. My color is actually called Tor Red, even though everyone knows it as the Dodge name Hemi Orange. Same paint code EV2.
