CAM 101
1st off, You need to talk duration. ADVERTIZED duration means nothing, has no reference point and is different for every cam manufacturer. Therefore talk duration at .050 lift , that's the only way to compare cams. Your 270 advertised duration cam is in reality about a 220 cam at .050 lift., a mild street cam.
2nd off, go to a real engine builder as you do not know what you're doing.
