V-8 swap

[jpsmith]

Does anyone know how to convert a 1987 ranger 2.9 Tach to read my 302 V-8

There's two thingy's on the back of the tach that can be adjusted to make the tach read correctly for a V8. But you need another tach to compare readings to do it.

The search function will tell you how to do it, too.
