For about $60 you can buy a Tach that reads a piece of reflective tape on any rotating element. This would be fine for diagnostic use & handy for checking machine tools etc.
A vacuum port could be drilled in the manifold if one is not already there. I have seen a plate with a port in it that would fit between the carb & manifold but I do not know if a reading there would be of much use.
Usually a T runs best when set up by someone who knows what it should sound like though. Your best information might come from looking over his shoulder.

I completely agree. T's are more like individual living creatures than exact mechanical clones of each other. They each have their own personalities and individual adjustment needs to run properly. A tach on a T engine will provide scant useful information, but if you insist, the model airplane guys have some really cool cheap optical propeller tachs that work on T fan blades if they are backlit.
I bought a TinyTac, but guess the install or the style unit I got was wrong for my '26 Touring, as it didn't work for me. But maybe someone else can get one to try, the lead wraps around one of the spark plugs and is supposed to catch the impluse to the plug.
