    I've been doing some research, and would like to know which of the 3 K-series "non-balancer" oil pumps to use. I am aware they are all 3 bolt-on's, and 2 need small mods to fit, but what are the actual differences in the pumps? Is the drive gear the same? Are the internals the same? Do all 3...
