331  Camaro Research Group Discussion / Originality / Re: correct shifter for 1969 on: July 23, 2009, 08:48:45 AM
The 3138 shifter body was used for several OEM applications.

I took a look at that add.  I think I would give them a call and ask the questions.  It does look
like it has the correct style handle (bayonet style handle - not bolt on). 

They might have listed the wrong number in the add (they have 3128 and original was 3138)
or maybe that is just the number they are using now.   Sorry, I don't have more answers.

I think they need to do some more cleaning and use a wire brush.  I don't see that code in
any of the documentation that I have collected. The format of the stamped code should look like

CB G 112 1 E
(CB = Ratio, G = Plant, 112 = 112th day of year, 1 = shift, E = Positraction Source)

Rich,

Check this link and scroll down to the transmission section.
http://www.camaros.org/trans.shtml#4speed

I believe the OEM shifter body is 3138 and it used a 5325 round handle.

I believe 391 7438 is the number of the current aftermarkt Hurst Competition Plus for a 69 Camaro.
This is the number for use with and without a console.

What ever happened?  What is the guy's name or did he decide to give you your money back?
335  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 20, 2009, 09:11:06 AM
I read through the gang stamp information.  I don't know if that was going on with the date stamps though. 

I did check the M21 in my car and it DOES have that small c or whatever character at the end.  I believe it is a
replacment transmission though.  Date code is after my build date by 5 months and so far I can't find a partial
VIN but it is probably on the top of the transmission.   
336  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 18, 2009, 08:41:34 AM
The gang stamp could help explain something.  I don't know.  It sure is not a true full size C because I have a picture of one with a March date code and it uses the full size letter.

It must signify something.  How about small c for "close" ratio - in other words NOT an M20. 

Did anyone try to cross check that?
337  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 16, 2009, 07:02:06 PM
Does anyone know anyone that may have worked at the Muncie plant in the early part of 1968?

338  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 Muncies - date code with small "c" at the end ? on: July 16, 2009, 05:00:23 PM
OK.  Thanks.  But that thread is over 2 years old.  Has anyone figured out any more since then?

Inspection mark is usually on the top of the transmission.

The small c definitely does not stand for Chevrolet since I have them on Pontiac and an Olds transmissions.

The initials mentioned on the side of the case in that old thread were probably scratched into the mold
by the person doing the casting.  Probably that persons initials.  I have one with MH on it.
339  Camaro Research Group Discussion / Decoding/Numbers / 1968 Muncies - date code with small "c" at the end ? on: July 15, 2009, 11:44:12 PM
OK, I know the codes for M20, M21, M22 (A, B, C) were not supposed to start until around late October 1968, at least on Chevy cars. But could Pontiac and Olds have started sooner?

I have a Muncie that I think is from an early 1968 Firebird.  The date code is P8B07c with a partial VIN of 28L100919.  I found pictures of two other transmissions with a similar small "c" stamp after the date code.  All stampings look very simillar.  I wonder if someone is trying to fool people that these are M22s or what is going on?  These are all from different parts of the US.  The trans I have was in an IMCA modified stock car, converted to a 2 speed with M20 gears in it.  So it was not fooling anyone there. I have gears to put it back to being a 4 speed M20.  I have never seen any of these small "c" marks on a Chevy transmission.  Does anybody have any ideas?

I have attached a picture.  This is from Muncie #2.  I have pictures of the two others but can't post now due to size limits.  I can send them to anyone interested that would like to comment.

Muncie 1 - the trans I have - date code P8B07c with a partial VIN of 28L100919
Muncie 2 - an Olds 442 trans? - date code P8C06c with partial VIN of 38Z117242
Muncie 3 - a Pontiac trans (GTO ?) - date code is P8A19c with partial VIN of 28P244597

Any help you can provide to explain this will be appreciated.

quelm,

Did you respond to the email from Kurt?

It is sad, but yes - if money is involved people try to fake stamps all the time.

For a rare car like you might have, I woud trace things back to the original dealership to be sure.
341  Camaro Research Group Discussion / Originality / Re: Help with 302 MO block repair on: July 13, 2009, 09:40:27 PM
If there is a will, there is a way.  I think the block can be repaired.  I know a place in Iowa that can probably fix it.  They fix 427 blocks
once in a while.

But yes, I guess it would be important to see if the original owner is looking for the block and that would be documentation for them.

It is important to know the VIN. 
342  Camaro Research Group Discussion / Decoding/Numbers / Re: 396/375HP on: July 13, 2009, 04:04:22 PM
wagonman,

What is the date code of the transmission in question?  Date code should be on the passenger side, near where the main case and tailhousing bolt together.   VIN will most likely be on the top of the transmission, near where the main case and tailhousing bolt together.

While it is in the car, it will be difficult to read the VIN on the transmission.  You can try a small inspection mirror with an extendable handle but even that doesn't work sometimes. 

343  Camaro Research Group Discussion / Originality / Re: Help with 302 MO block repair on: July 13, 2009, 03:15:10 PM
Take pictures before you do anything. 

Ask if they can deck the block but leave the stamped pad intact.  They might be able to "stop" the decking process before removing the numbers. 
If they don't already know let them know it is a rare block.  They might be willing to work with you.

Or at least deck it the LEAST amount possible to leave a weak stamp.  But if that does not work and it's gone, you are out of luck.

I would strongly recommed that you DO NOT RESTAMP IT. 
344  Camaro Research Group Discussion / Decoding/Numbers / Re: Is this an L89 aluminum head eng.? on: July 13, 2009, 03:05:37 PM
Is there any chance you can check with the dealership that sold the car originally to see if they have any records of it?

Are you trying to buy the car?  Is it still in the family?

I have my doubts too, but I am very interested and would like to know more. 

Check the date code on the block and heads.  Does the partial VIN on the block match the VIN of the car?


345  Camaro Research Group Discussion / Decoding/Numbers / Re: 1968 12 bolt code on: July 12, 2009, 08:17:30 PM
Lane,

Date code is always 4 numbers.  So 0 1 1 5 is January 15.
BS is for for 3.31 posi
