4-speed! To clarify, the factory trans in that case would have actually been a Saginaw behind that LM-1 350. The Muncie was last produced in 1974 but was not used in Novas once the compression was dropped for 1971.

The rear gearing could actually have been 3.42:1, even in 1975.  I think 3.08s may also have been offered.

As the "Fonz" would say.........I was Wrr, Wrr, Wrrrrr. I stand corrected. When it comes to the "Muncie" trans, I went partially on the previous owners word and by sticking my head underneath and I saw that it was a cast steel case not alluminum. Then if you look at the build sheet, GM uses "M20" as the manual transmission production code. I knew that M20 production code only meant that it had a manual trans and not nescessarily a Muncie. Although the Nova site I was on did list a Muncie M20 as an option in 1975. So after owning the car for 10 months, and after listing it for sale, I decided to finally put it up on the hoist and get underneath it. It appears to be a cast steel housing Saginaw 4 speed trans. So at the same time I ran the gear ratio because I was still going on the previous owners word, and it is a 3:08. So like I said at the begining of this reply, I was Wrrrr. Damn, it's like you guys know your S*#t on here. I am currently trying to corract my ad, but not having much luck. I might have to redo it.

For some reason I had it in my head that Saginaw had a alluminum housing.

 I always use for a quick glance to tell the differance between the trany's is the location of the reverse lever. On a Saginaw its on the side cover on Muncie and T-10 is on the tail shaft.
