None, at 5500 rpm that I know of. L-36, L-68, and the 1971 LS-5 engines had a redline of 5400 rpm; the L-46 and 1972 LT-1 engines had a redline of 5600 rpm.
If there is one with a 5500 rpm redline, what is it?

Wilcox has just finished with my gauges so I will re-check the red line on the Tach when I get it back.

The L36 redlines at 5600 and the L68 should be the same since it is the same valvetrain but has the 3 deuces. LT1 redline should be above 5600 since it shows that RPM as the power peak but I don't have time to verify that.

The reason is stated here- http://www.vettefinders.com/index.cf...ifications.htm

....but HONEST!!! 
If the '72 tach for the LT-1 was set at 6500, so be it. But, I'm not sure the '72 LT-1 engine would actually wind that high.
My info (unofficial) indicates that peak power for the '70 LT-1 was at 6000 rpm; for '71 at 5800 rpm; and for '72 at 5600 rpm. I guess the 6500 redline was just a marketing ploy...

You must be one of the ELITIST NCRS members. There are many who are not, but your attitude demonstrates that you are in that 'mold'.
