Just checking numbers on an LT1 I bought. The side cover is 3952648. Tail 3978764, Main 3925661. I think it is an M21. Has anyone seen a code like this photo? Perhaps a rebuild number? Says CCI 3790 and then what looks like a reverse S. Doesn't like original was ground off but maybe

If there is no VIN derivative stamped on the case, then this is likely a SERVICE replacement main case.In Appreciation of John Hinckley- Top

Re: Numbers on Muncie Transmission
I have a 67 service case that has nothing stamped on it, but I have seen the CC1 mark on later cases. It must be just a service case because a whole service trans would have the Muncie date stamp but no vin.- Top
