decodeing a Vin on a Muncie from 1970???

[budnate]

need a little help..I have a M-20 wideratio Muncie and I cant seem to figure out what it was in from new.

PO614 I assume is a 1970 casting number.

and ontop of the case is stamped 6Z154668...the Z is not in anything I have or found online..anyone know whats up???

Thnx Bud.

A guess?
That looks like a VIN#.
6-year 1966
Z-Fremont plant
154668-Last 6 digits of Vehicle VIN#.
In 1966,Fremont Calif. built Chevelles/Elcos.


Muncie Date code.
P-Muncie
06-Month June
14-day

I saw the Z refering to the Fremont plant but I thought it did not come into play until after 72 or so... at least thats what I think I read on a forum when I typed in Vin decoding as a search on yahoo...thats what is confusing to me P0 should be 1970 right???

Z indicates Fremont in 69 too.

What is the main case casting number?
65-67 should be 3885010
1970 would be either 3925660, or 3925661.
Should also have the ratio designator (sp)after the date code. (69-74)
A = M20, B = M21, C = M22.
661 would also have a fine (26) spline input, turbo 400 style output, and a drain plug.
