jg33replica 4 Posted August 5, 2021 Just looking for any info on modifying Crossflow oil pump. Standard volume Mellings will be used. From what I have read some believe there are certain modifications that are beneficial to a Modified Crossflow. I guess asking Mellings what the pressure relief spring is pre-set at and deciding on a pressure spring that matches the desired max revs might be a start. would like to hear from those that have performed mods and know first hand how to do it. Starting from scratch so block ect will have oil passages played with to return oil as quickly as possible so any knowledge there would also be helpful. cheers Share this post Link to post Share on other sites
