305 or 351e V6 factory tach?

I'm thinking of purchasing a 67 gmc with a 351e engine. Did those ever come with optional tachometers?

I would think so. I put a 6 cyl tach in my 67 with a 305

Was it accurate? So a 6 cylinder tach is good for inline 6 and V6 engines?

It seems pretty close, but have not had another tach hooked up to verify. The tach head doesn't know if it is an inline or V-6, so you should have no trouble as long as it is a 6cyl tach.

I believe you need a sun 6 cyl transmitter box for the tach to work, and they are very expensive!

Mine just plugs in like all the other 67-72 tachs. I know the earlier 60s tachs needed that box.
