Just stick a straw in the plug hole and watch it. It can't hurt anything, and it's much more accurate. But, that could still be 180° out. If the rotor is way off, turn it over again. If the valve covers are off, it's easy. Just watch the rockers.

I now remove #1 plug , and as I pull the engine up to TDC with a wrench, I make sure I can feel air coming out of the plug hole. My thumb works well-at least it has worked well for the TR and the Jaguar engines! I haven't needed to try it on my 300H. (I have seen a whistle device which screws into the plug hole for that same purpose.) That way I'm confident its not 180 out, and I have less anxiety when the engine is grinding away. (Another frustration factor----who would have thought you could reassemble a Lucas distributor with the rotor shaft 180 off?-but that's another snake in the grass!)
