What does a Pontiac engine block look like?
Whether the engine is sitting in a car, on a stand, or on the floor, at first glance you will note that all Pontiac blocks have a hydraulic lifter valley pan. That simply means that the intake is not sealed to the lifter valley, allowing you to remove the intake while the engine remains sealed.
