Small Block Oil Pick Up Tube Question

grimreaper said
Can anyone provide information on what modifications have been used to allow a greater flow of oil into the oil pump? I have applied several oiling system modifications thanks to the great write up by Guitar Jones but I have a mid sump pan in a passenger car so there is no room for the pick up tubes from Canton or Champ with the tube going into the bottom plate of the pump. I have a Moroso and a Miodon pickup tube which are suppose to be high capacity but they both neck down to a small diameter to fit the 3/8 NPT pump threading. I can drill them to 7/16" but that is still the bottleneck in the system when everything else is opened to 1/2". Has anyone got some creative ideas to get a proper amount of oil into the pump other than drilling the pump and brazing a 1/2"ID tube in?

I got this idea from Rapid Robert to drill the pickup passage to 11/16 and tap it with a 1/2npt tap. You have to have a pump housing that the pickup hole is in the center an not drilled off to one side to do this.

The hole is not deburred in the center picture yet.

I'm using a Small Block 727 dipstick tube to make my new pickup at the moment but will probably cut the end off of the Milodon pickup then thread it, screw it in to the coupler and weld it to it.

I also did the Guitar Jone mods and use a stock center sump pan.

OK now everybody tell me how it won't work and will suck my pan dry.
