Re: MUNCIE METAL TAG ID
Although printed in a Chevelle themed publication,those are not Chevelle specific.
Yes,other vehicles shared them. |

Re: MUNCIE METAL TAG ID
Tag Number 3946767 in the list from the Chevelle report is wrong, should be 3946797... Crash

Re: MUNCIE METAL TAG ID
The 3946797 is for the 1969 M20 Trans. I'm looking for 3946798 if anyone has an extra.

Re: MUNCIE METAL TAG ID
From the assy manual for 1969 Camaro (don't know about Chevelle or 67-68 Camaro)
3950356 is for RPO M20 with L48, L34, L35, LM1 3946797 is for RPO M20 with Z28 & L78 3950316 is for RPO M21 with L34 3946798 is for RPO M21 with Z28 and L78 3950318 is for RPO M22 with Z28 and L78 Evidently, from this and from the RPO spreadsheet file in pdf available at camros.org, you could not order a close ratio (M21 or M22) unless you had L34 (M21 only) or Z/28 or L78. Now, for another question: Why is there a different tag number for the M20 behind a Z/28 or L78 as opposed to the one behind an L48 engine? They would be identical outside dimensions. The Z and the L48 would have identical shifters and brackets. Was there anything internally different between a Z/28 M20 and the regular small block SS M20? There had to be something different about these transmissions to warrant different tags. Maybe the standard rear gear ratio? |
