Now as far as cam size goes, BP stuck in a small stick to make this thing produce torque very early and @ a 396 CID, it should be making a lot of it. This is huge street car fun. They (BP) chose a “Street” cam for this purpose. Not a huge lift cam so it can be easy on the springs for longevity and enough duration to make it a good driver with a mild stall converter and appropriate gear selection.
