273 cam suggestions

The one question that hasn't been asked is what are going to do with the car? Drag race, autocross, street?? Sounds to me it's more of a street car with 3.23's. Having a lumpy cam for the sake of bragging rights is not worth the effort of having a big cam in a small displacement motor driven on the street. E4 is the way I went in my 64 vert.
