finally got to the tear down phase of my 71 Bonnie engine ..made a stand, labeled all my parts bags, and got the rocker boxes and head off,, nothing serious, lots of carbon and a broken 1/4 box bolt., tied off the tappets to keep from dropping and got to all 8 cylinder base nuts, so far so good,,, then brick wall... cylinder wont budge from the block.. tried tapping all around with wood mallet, then deadblow, no luck... have it hanging by nylon strap from my hoist, with penetrating oil squirted liberally. but I am not counting on it...any ideas to release without damage to fins, etc.. ?? sure don't want to go the chisel route...
