Yeah, since "factory specs" doesn't mean anything with this engine, I use the vacuum gauge method: Set the timing at idle (set as low as possible) so you just get maximum vacuum, then back off the timing until the vacuum drops 2 in Hg. When I do this, it usually comes out about 12 deg BTDC (though it's kinda hard to check now with the multi-spark Street Fire ignition!).
