i'd always purchase the 4-vane pump , then you can tailor vacuum amount easier to what you want

sometimes 3-vane is not enough

the larger CID of engine
the higher the compression ratio
the worse the rod ratio
the worse the hone job/ring seal

the more the vauum pump will gain Torque and HorsePower
