If you were going to change your stock 302 cam out of your Z at this point would you replace it with a better, higher lift/duration after market unit or something like an NOS 140 cam? Which would be faster and better suited. Do you think maybe Comp Cams makes a better all around suited performance cam than the 40 year old Chevy design? Thanks, Sam

Have seen reports on this G. Sommer's Z28. Car appears to be very fast and set up by McNeish, runs in the mid 13's with street tires and closed exhaust?
