My 6 year quest for a CX coded THM400 just ended

[Mr70]

Nice find,and good looking Original CX tag as well.
I wouldn't balk fo a minute on that engine timeline,it all seems acceptable.
Even that Trans. falls into perspective.
C=Chevrolet
X=Solid Lifter engine applications
69=Model year
2160=Serial No. My records show this falls into the right time line.
395=Assembly day starting with January 1st,1968 which decodes as Friday January 30th,1969.

Just curious..Have you thought about hunting for the Nova itself these came out of?

Rick,

The seller told me that the car was chopped up for racing
many years ago. No idea of where to find it. You know
how these stories usually end.

One question though. Can you tell me exactly what the
2160=Serial No. pertains to? How did you determine the
time line based on the number?

Chevrolet kept track of some of their Transmissions for service reasons through their serial numbers.
Yours was built at the Cleveland Plant.
They produced a spiral bound catalog.
I own that catalog.

1968 was a leap year (366 days) so the assembly date should be Wednesday, January 29th, 1969 unless they stuck to the 365 days in a year as the standard rule. The 30th was a Thursday as well not Friday.

You're right,I was looking at my January 1970 calender.
