Because this is more of a ENGINE type question ... and there has been quite a few views here in General Rodding Tech without reply I am going to move this to the ENGINE forum.

I don't have any input but I'm curious as to what your new time will be. Do you have the suspension to plant the new found power. Must be nice in Florida. It's currently -6 here.
