I went to SC cams with timing set at 1.65 mm with the stock ports and I'm very satisfied with the performance. Second gear is a blast and reminds me of my big block Corvette that I owned long ago.
Fred, it could be that the SC cam does not have enough duration for your enlarged intake ports. You are not getting the cylinder filling that you need for low-end torque.
