Early 283's used the tube in the intake for an oil filler so the valve covers would have no intake hole & cap. If that's what you have then you must replace the valve covers to a later style with the hole or else no way to put oil into the engine. I think that was changed around 63-64 or thereabouts. The aftermarket aluminum's have no filler tube provision.
