So In a Mopar small-block, the right oil gallery supplies the No. 1-4 mains, and then the oil transfers back up from the No.1 main to feed the left gallery. so you blocked the right side feed to the No. 1 main, and fabricated a 3/8-inch tube crossover, which supplies the left gallery, and sends oil down to the No. 1 main from there. This mod helps with main oiling at high rpm
