1969 Nova L78 M22 4.88 on Lost Muscle Cars
 

that was well worth the read. Unbelievable car with great window sticker and pics. Thinking about the 6000 miles with those gears makes me wonder if he changed out the rear gears vs if those were all on the 4:88. Holy grail car.

more holy grail if it was a 68 but still a cool car!

Looks like a sweet car. Wonder if it's still around??

1969 Nova with special order 4:88 gear ratio is very interesting.

For some reason 69 Chevy Nova Power Team charts list the highest number gear ratio as 3:55 with the 375 HP L-78.
1969 L-78 Camaro and Chevelle Power Team Charts list 4:10 but Nova lists 3:55.

The 1969 Yenko 427 Nova ads list 4:10 gears same as the Yenko 427 Camaro and Chevelle.

I have been looking for any documentation that Yenko some how got the Novas built with the 4:10 gears to save the time and cost of changing the rear gears.

I was thinking Yenko either did a special order rear gear or a COPO 9511

The COPO 9511 was used to get 4:56 or 4:88 in 1969 because the Power Team Charts list 4:10 as the highest. I have seen documents on COPO 9511 4:56 or 4:88 on 1969 Camaros and Chevelles but not Nova.

This 4:88 Nova appears to show a special order and not COPO 9511 on the build sheet.

How so?

just not many 68 l78 novas built. 667 in 1968 and 5200 and change in 1969.

Hard to read the window sticker clearly, but I think I see '9511' followed by two letters on the left side of the line where it lists the axle ratio. Too bad there was no picture of the Trim Tag, but no one paid any attention to those back in the day.

L78 Nova...
 

I don't think the number built really applies once you drill down to 4.88s. I'd imagine less L78 4.88 '69s built than '68s.
