Tach used was a '66 GTO tach can't say for sure how much lower the RPM reading would be but sure seemed close. There are plug in units that can be used to adjust the reading and or you could mod the V8 circuit/capacitor. Knowing what the V8 Tach were worth back then I did not mess with it.
Back to wagon Talk;
Here's one that I almost overlooked, and IMO is even rarer.
An OHC 6 '68 wagon. Not a 4BC, but great wagon/lines in '68.
