My take on the oiling system crossover tube for the small block
Oil Pump Mods
All these oil system mods will amount to a pile of scrap metal if you can't get enough oil thru the pump. Milodon and Moroso no longer make the high volume rotor pump kits. The hv pumps are still restricted by the 3/8 npt inlet. Then comes Kelvo and Canton oil pans, they use the bottom pump plate pickup for oil intake on their rear sump pans. These pans and pickups are great if you have the room, and aren't running in stock eliminator where a stock pan is required.
What I am doing where a stock pan is needed, is to drill the inlet out to 1/2 npt on a HV pump.
Then the 18650 Milodon pickup is fitted with a new 1/2 pipe thread end.
The left pickup is 1/2 npt inch and the middle and the right are 3/8 npt.
While the pump is apart it gets the output passage drilled to 1/2 then deburred, cleaned and a new Hi Pressure bypass spring installed.
