c3-71 Lt1 - how many with 4:11's?

[Peter M.]

Was looking at spec guide to determine how many purchased Performance rear option in 1971 and how many of those were 4:11's. Is there any info out there on that?

Thanks

For 1971, the 4:11 rear ratio was only available with the LT-1, although it's possible that some of the handful of ZR-2s built that year might have gotten it.

Unfortunately, the RPO ZQ-1 optional axle ratio applies to any optional axle ratio and, as far as I know, there is no breakdown available as to how many of each were installed on any model, let alone LT-1s.

Thanks for the feedback Joe!!! *NM*

Joe: All the information listed in many publications, indicate that either 3:70 or 4:11 ratio as optional on M22 equipped LS6's. How do you know this not to be true?

Yes, 4.11 was available with LS-6 with M-22. Since there were only 130 M-22's installed for 1971, there was likely not too may that also chose the 4.11 ratio. But, it was available.
