621 Bell housing First design
 

Anyone have a picture of a first design 621 Bell? I'm looking for a correct Bellhousing for a 67. What I have now is a 621 with GM logo and part number on the side.Not sure if this is correct for 67.
Thanks, Steve.

The correct early ones have the thin crease down the middle outside.

You're welcome Steve. Good catch on the location of the GM. I have three or four at home. I'll try to check for some date codes to see what the differences were.


edit: I just happened to find a pic on my bucket acct of the date code on the one I posted. I'm not sure if I can remember how to decipher it though.
I just found this post talking about it though: &quot;According to &quot;corvette&quot; Lore there are 2 cricles.The one refer's to drawing revision'sbut, the other that you are speaking of is the dating of the bell.
In half of the circle you have a &quot;9&quot; ,that is the month,or Sept. In the other half you will find &quot;Dots&quot; or week of Prod. &quot;3&quot; would be third week.
As far as years go there is no year date on the Bell. Some have a larger # cast in the same area (2-9) but not all, refering to mold #'s.
<span style="color: #FF0000"><span style="font-weight: bold">Again Corvette thought are '67 cars got the &quot;GM&quot; cast into the top center of Bell above the trans.
And it is beleived '68 was the change to put the &quot;GM&quot; down on the side by the Pt. No. And this is the theory that most go by</span>.</span>
Hope this helps, Joe.&quot;
