OK thanks for the input. So I can go up 3 cam sizes and still should pull plenty of vacuum. I just don't want to put to big a cam in it and be unhappy. The roller cams aren't cheap. Do to hood clearance I don't think an Eddy RPM will fit. More than likely will have to use a low profile single plane like the Holley Street Dominator or an Eddy Torker II.
