Re: Chane rear spark plugs
Most folks do it while the car's on a hoist with a ratchet and extensions. I've done it with removing the upper dog bone engine mount, then loosening the front 2 engine cradle mounts and lowering the engine slightly. As the engine lowers it tilts forward. I used DELCO platinum plugs for a newer 4.9 V/8 Cadillac. Be aware you will more than likely damage the plug wires so have a set of DELCO wires available!
