Any one interested in the oiling mods I did?

What those pics don't show is what sort of line is feeding the front feed tube once it passes through the rear of the block. I assume he used a -10AN hose but?
You have not read the Sanborn thread, he tells you to use a 12an feed hose for the main feed to the rear of the block. He uses an 8an external line to the front as the front is not about volume, but turbulence. To stop the turbulence does not require big volume.
The main feed goes back into the block in the oil filter area.
That is the best way. Medlock also shows some of Sanborns cooling mods in those pics.
