Chilton's says to install cylinder head, piston #1 should be at top dead center while the camshaft pulley reads "UP". This sounds pretty simple to me. However, I have a friend who's a mechanic and he insists that I remove the crankshaft pulley in order to see the timing sprocket, which also has marks that need to be lined up correctly. I would be okay with that, too, if the crankshaft bolt wasn't installed at 180 ft. lbs. of torque. My air compressor and impact gun don't do the trick. I've also tried heating the bolt. The next method I'll employ is removing the starter to access the flywheel, which I can have my neighbor brace with a prybar while I jump from the roof onto the two-foot lead pipe slid onto the rachet. Before I do this, my questions are: a) Is there a way to have everything lined up absolutely correctly without having to remove the crankshaft pulley? b) Any more suggestions on removing the crankshaft bolt? Thanks.
