I have a 350 from a 74 Corvette old LT1 style and the pilot bearing/bushing is stuck. Like literally, stuck. I have used a puller, tried using hydrolic pressure with grease, but it will not move a millimeter. It is a brass bushing and NOT a bearing. Is there something else that has to come off? I was told to drill it out a bit, then break it to pieces and pull the pieces out... Is this right? The flywheel is already off. Anybody know how to get it out? Thanks guys!!!
