Okay, that one confused me. How do you get more lift using a cam designed for
a larger lifter. When the cam is at full lift on any lifter it is in the
center of the lifter. Are you saying you can use a higher lift cam that runs
off the edge of the lifter to get more lift?

lifter is the SBC at 0.842. I've often wondered whether some of these grinds
find their way into Spitfire and TR6 engines with the 0.800 lifter. The
result would be a cam that would run off the edge of the lifter. One can
always get more lift by using a cam designed for a larger lifter.
