It most defiantly was not a waste of your time.
The first time I saw these mod done was 1977 on Carl Harvey's 340 that he ran in his old John Force funny car in econo funny. That motor was freshened up many times over the years and was last freshened up in 2008 but not put back in a car at that time. Carl died last Nov but that small block still lives because of these oil system mods. We use to call it the, A & W oiling system mods.
Thank you again Guitar for showing us the ins and outs of how to do this.
