I have a 6000 redline tach that came out of a x-22 car.Could anyone tell me what horse power it may have been.Thanks.

Tachometers have no horsepower ;)

Weren't the 6K redline tachs only in Z-28 and 396/375 cars ?

That's what I've read....

This would verify what you are thinking. If all else fails see what CRG has to say. graemlins/waving.gif

If it's an 8000 rpm tach with a 6000 redline it could be Z-28 or 396-375. There was also a 7000 rpm tach with 6000 redline that was 396-375 only.

The 6000/7000 tach was also used for Z/28s until about February '69. Also used on both COPOs.

A relative has a 325/396 car purchased new. Has a 6000/7000 tach. This why we CRGers like to say "normative practice."

6/7 tach was for L78 and L72 for the entire model year.
It was used on Z/28 until early 69, and then switched to 6/8.

I've always been curious as to why the switch on Z/28, and not the solid lifter b/b.
