Waaaayyyy back on page 3 of this thread I posted that a friend of mine bought a new 70 Nova L78 with 4.10 gear.
Mea culpa
Talking with him last night he said it came from the factory with a 3.55 gear. Very shortly after delivery he had a mechanic friend at the dealer "confirm" that his ring & pinion was "defective" and GM warrantied a 4.10 gear into it. That's why I thought it came from the factory with the 4.10. Sorry for any confusion
Even the 4.10 didn't stay around long, as within a year he had a 4.56 in it - at his expense
