new hemi mpg in an Abody?

Are you using the stock k frame or an alterk? I say this because most people have to notch the factory k frame, and the alterk allows you position the engine if you want. Now some frames where a tad wider due to "bad" tolerances from the factory, I mean the lip of the frame rails. B and E bodys really dont have that concern since they are wider to start out with.
