Small Block Oiling System Mods

I know it may be the wrong time, but if it were me, I would order a set of lifters and the cam, then install them in the block and check. I dont trust the cam companies..Not because they are out to mislead, but because there is no way for them to know that every single block has the same size passages for each lifter, and it's the casting that determines whether or not the deep skirts will work. For what it's worth, the 416 I'm involved with for a customer we are bushig the lifter bores instead of tubing the block or running the heavier lifters.
