Just a note on Moroso Race OIL FILTERS (427 FE part number, 22470).
Gessford (George) recommends the Moroso Racing Oil Filter, which is what I'm using. Flitering out extremely small particles of 20 micons or so is pretty standard for most filters. This requires a very fine mesh filter which causes to much oil restriction. When the oil flow is restricted it "by-passes" the fliter via the internal valve built in to ALL oil filters. That results in NO FILTRATION at all.
The Moroso filters 27 Microns with an initial pressure drop of only 2.5 pounds. This assures full filtration under the most severe oil pressures typically seen with Big Blocks. Like 70-80 PSI when the oil is cold on start up. Less Restriction, More Flow!
Initially I ran the motor a little more than 30 minutes at varying engine rpm around 2000. Then a short drive around the block. Then I CHANGED the OIL and FILTER immediatly! The oil was all ready black (must be the Marvel Mystery Oil doing it's thing)!  |
