great info Jerry (thanks for taking the time). One question, when I get the BB (I had long ago 'painted' it to show up) by slowly cranking the engine AFTER getting compression on #1 cylinder, won't that then take it off the highest level of compression. So I'm guessing that to be timed correctly, the highest compression level must coincide with BB pointed at pointer in bell housing.

I thought getting the highlest level of compression denoted TDC, and that using BB meant that dist. rotor could be placed over #1 or #6, meaning it could be 180 degrees off.
