	Recently I've seen an advertisement for a slightly
modified hydraulic lifter that enables the use of a
higher performance camshaft and still retain some decent
low end manners.  These lifters had a small groove machined down
the side of the inner sleeve.  Its purpose was to keep the
lifter from pumping up fully until a higher rpm.  This keeps the 
overall valve lift and duration down a little until there
is sufficient rpm to keep the lifter full and at maximum lift.

Claims include smoother low end running while maintaining high
end performance of "hot" cams.  Anyone ever try any of these??
I think a set was $89.
