Going from the stock 3/8s pick up to 1/2 inch. I take it u just drill and tap inside the block for the 1/2 pick up or do u drill farther in? Do u guys drill out the main to cam holes bigger? What about inside where the oil pump bolts on. This is a 505 that will be shifted at 7000 with Indy SR heads ported to max wedge size. SR heads have oil lines on the rear to oil the rockers. I do also have a single line Milodon oiling system. Thanks for all the pointers. Very much appreciated...
