68 car Muncie casting numbers controversy
Some trustworthy folks on the forum have told me with almost 100% confidence that a 68 Vette built in late 67 can have a 010 Muncie maincase casting number and have even had cars like that.
I just received an e-mail from a highly regarded Muncie builder stating the following.
"No, you will never see a 010 case dated with a P8 stamping."
(P8 meaning 1968)
I was wondering what others may think and if any of you NCRS members can ask the question of their experts on their website I would sure appreciate it.

That's a pretty good clue who I got the info from. But still I have another guy who is quite respected on this forum telling me that he has had a couple early 68 cars that he believes were original cases and they were 010's.

not that this has anything to do with a 68 or your particular issue per se....but this is my original m-20 transmission stamping with my vin number out of my 74 corvette ls4 convertible - please notice that it is stamped "73". the car has an early build date (#8167 built nov. 5, 1973)
but it was still in a 74 corvette - and not SO early that i would think that they had that many trannys left over unused from the 73 production run....so here is proof ANYTHING could happen....

Just to be clear, your car is a 68 model year, right? I assume so, and if yours was built before mine more than likely 660 is the right one. And who knows maybe there was a transition period and some overlap. It happens in factories all the time. I bet either are possible but 660 is the rule and 010 is the acceptable exception.

As a side note, does Internationalblue have your car info? He is collecting as much information as he can on all cars built in October 67, such as yours,mine and his which was right in front of mine on the assembly line!

The stamping on the tranny is:P2K 06A C11S121653
Notice the P2 --at the plant in Muncie, they assumed this would go into a 72, and stamped it accordingly--it actually was installed in late 71, and the VIN stamping was done in St. Louis, of course. Yours is the opposite, but the same kind of incorrect assumption.

I have a 30k mile 71 LT-1 Convertible. It is 148 from the end of production (It is #21653). Nothing has been messed with on the car--still has original exhaust, plug wires, etc. The trans has the VIN stamped on it as it should.
