The Vortech supercharger uses engine oil to lubricate the gears that turn the impeller. On current small-block Chevy applications, Vortech recommends removing a 1/4-inch plug in the block located above the oil filter for the best source of filtered oil. Ken found that his '65 327 block was manufactured with a welch plug that would be difficult to remove, let alone tapping the block with a 1/4-inch NPT thread. He resolved this problem by inserting a 1/8-inch Tee in the line that is used for the oil-pressure gauge in the dash cluster. The fit is very close to other components, but it made a very clean installation. A return oil line is plumbed from the bottom of the supercharger gear case to the oil pan. Ken attempted to find an aftermarket oil pan to avoid cutting a hole in the original part, but found that current S.B.C. aftermarket pans are not designed for this vehicle. He finally gave in and cut a hole in the pan and welded a 1/4-inch NPT fitting in the left-front side. This was the only original part on the Vette that Ken had to modify in anyway.
