I'll try, but it's not happening soon....
Not an easy topic and I have enough pet projects.

Re: MUNCIE METAL TAG ID
 

I agree with the 6767 issue,all Chevrolet materials I've seen report it should be a 9.
I have two actual 9 tags here as well.
I can not confirm if this typo was made by the author of the list or the source he got it from,but it does look like an error.

Take this with a grain of salt as my records are not as complete as others.
I'm finding the Muncie M-20 #3870372 was installed behind the 1966-67 396cid &amp; 427cid vehicles only.
It also shows when the 1966 Passenger series got a 327cid,it got Muncie M-20 #3884603 (Not used behind L-79).
A friend of mine who owns a 1967 327cid Passenger series has an M-20 w/#3916108 tag on it.
I'm sure crash could help narrow this down some more.

Re: MUNCIE METAL TAG ID
 

How about this tag number 3964502? Was in the bucket that held a CE stamped muncie m 20 all there but in many pieces. Thank you for the information.

Re: MUNCIE METAL TAG ID
 

That's a Muncie 4spd. 2:52:1 ratio used originally in:
1968 Passenger series w/396cid &amp; 427cid.
1968 Camaro,Chevy II w/327cid &amp; 350cic &amp; 396cid.

And recommended replacement in:
1967 Camaro 350cid &amp; 396cid.
1966-68 Chevelle,Camaro 327cid.
1965-67 Passenger series.
1966 Chevy II.
1965 Chevelle,Chevy II.

Re: MUNCIE METAL TAG ID
 

Well, while were at it whats this # 3915077

Re: MUNCIE METAL TAG ID
 

That's a Muncie 4spd. wide ratio 2:52:1 as well.
Used originally in:
*1968 Passenger series w/8.15 X 15 tires w/3:55 axle AND when 396cid or 427cid. equipped.
*1968 Corvette w/o Posi or 3:55 axle.

And Recommended replacement in:
*1965-67 Passenger &amp; Corvettes when NOT close ratio equipped.
*1965 Corvette w/o Spcl. Hi-Perf or Fi.

It was soon superceded in 1970 by Muncie #3964507 for same applications.
