I don't know for sure, but I rather doubt that the Smith tach would work at
all with the V6. The pulse count would be off. Most aftermarket tachs have a
3-way switch for 4/6/8 cylinders. The Smith was, of course, not intended for
other than 4 cylinders. I don't know if you could use an MGC tach in its
place.
