It rides directly on the original pinion it was going to ride on with the dual idler set. I just drilled a hole dead center of the pinion so I could bolt the whole thing to the front of the block. As for oil, I chamfered the top half of the front main bearing from the center groove to the front of the main so it will get pressurized oil at the crank gear and I also drilled a 1/16 hole through the main oil galley plug right behind the cam gear, so the back of the cam gear will get sprayed. Oil will be everywhere under the timing cover. Yes, I plan on running a high volume oil pump.
