Steve,

In 66, each of the four available engines had it's own unique instrument cluster package. The base 300 HP 327 used a 60 Lb oil ga with a low RPM tach. The 350 HP 327 used a 60 Lb oil ga with a mid range tach.

The 390 HP 427 used an 80 Lb oil ga with a low RPM tack, and the 425 HP 427 used an 80 Lb oil ga with a high redline tach.
