I like the -140 cam in my first 69 Z. Ran one in the 70's with 12.5's, 4.88's, a little head work on the street with an M20. Car was a handful to be honest, but it sure was fun when 260 was still available. I ran a -140 a few years ago with 4.10's and 11's with an M20 in my current Z and it seemed to be more under control. If I remember correctly that cam doesn't come in until 4500 rpm. I'm sticking with the 30/30 myself and replaced the 4.10's with 3.73's More street drivability.
