YR, Because that cam line has more complaints about it than any other combined. I'm not so quick to blame his short comings as fault when many other very competent builders also have the same comment.
Lomchivox, increasing low end torque (simply) would require a reduction in cam duration. More vacuum should result. Also helping would be a wider 112 instead of the 110. The engine would have of a chop at idle.
I enjoyed this cam very much in my 318's. it is small but does delivery good torque nearly off idle and hp until about 5500 rpm.
