Dave, thanks for advice. I was thinking the same thing because this motor was specifically put together with this combo, but my buddy has this just sitting on the shelf. I am trying to get the car down to that index before the hot rod reunion next month but don't think it is going to happen this year. What I need to do is send my converter to continental to be redone for this motor and car. It currently is only a 4500 and should be around 6000 or 6500 which should definitely help the 660ft time. Not enough time or money as usual. LOL
