Bought 70 L78 Nova w/ following codes sight unseen

[L78steve]

In 1970 The L/34 tachs had a 5500 red line. The L/78s had a 6250 red line.

Does it have any racing history?

Mine is like the bottom...says 5500 but it is a 6000 tack. Have seen this type in several ads for 70 l78's over the last 2 years.

The one at the bottom is a L/34 tach. There are no L/78 tachs on that link.

All three tachs (small block, L34, and L78) are represented. There is also a fourth with a different yellow / red that has only been seen on the '70 Nova L78. That fourth one is shown in this thread.

The third one on the link is an L78 and has been seen in '68/69.

Also, the RPM numbers listed in the link should refer to and say YELLOW line instead of red line.

Ok so help me out...so you are indicating that it is your understanding that tach in the bottom AND the one with the heavy yellow and red were both in 70 L78's?

Hello Allen,

Updated the link. Will add a better picture of the last tach when I get home from MCACN.

That is the 70 L/78 tach in the above link. There are no other versions of that tach in 1970.
