My original concern is that it seems pretty senseless to do all of the nice oiling mods presented by Guitar Jones which includes drilling the block to 1/2" passages and then only allowing less than 7/16" volume into the pickup end. Back in the 70s there was an engineer for Mopar performance who used a test engine with various pickup tubes and proved that even the stock pump with adequate pickup capacity would put out more oil than the high volume with the standard capacity pickup. Oil control throughout the entire system is very important. I am looking forward to the results of the Milodon Hemi tube fitting.
