Crane's energizer cams

I run one in my 71 Charger. 360 .030, Sealed power flat top pistons, 1.88 "J" heads port matched 3 angle valve job and shaved .050". Eddy performer RPM, Holley 670 street avenger, Re-curved dist and converted to HEI. Headers 2-1/4 duals summit turbo mufflers. I was getting 16.5 mpg out of it with 3.23 rear and a REALLY worn out 727. I just put in a new lock up 727 with a factory High stall converter and hoping for another 1-2 mpg as the builder claims.
It's very streetable, has a slight lope pulls really hard. The best $99.00 cam/lifter kit I ever purchased.
I can post a video if someone can tell me how to do it.
