Thanks, Bryon. I would like to keep the engine as factory as possible. So, I'll see if I can find some of the 3911023 pistons.

Goodday,

I'm in the process of rebuilding my 67 350 and I'm trying to figure out how GM numbered oversized pistons.

The factory pistons in are GM 3892673. The block needs to go 30 over; would the part number just add a -30 to it?

IE GM 3892673 -30 for .030 oversized? Looking at some documentation GM made replacement pistons in both 4.0287 and 4.0307 sizes.

Thanks for any insight.

With a ebay user name lik, $bringmoney$ you know everything is overpriced.

123 VIN

God I hate flippers and dealers.

Wish it was closer, I'd love to help but bother are 2+ hours away and north of Atlanta to me.

According to the CRG information below, the manual transmission carburetor ID number was a 7037203/7037213, with a 7037202/7037212 used for the automatic transmission:

There are different part numbers as you posted for automatics vs manuals, air or no air, and also based on early, mid, or late build dates too.

No, that's the model year vs calendar year. https://www.camaros.org/geninfo.shtml#modelyear

The stamp must be T9M22D.

A close up of the stamping; it looks like an 8 tbh.

This Listing Isn't Available Anymore
It may have been sold or expired. Take a look at these other items below.

Woops, I missed that it is dated 68 model year. Too late for your car, it would have been T7xxxx.

Kurt,

I was a bit confused by the examples on the trans page.

Examples:

     R7S21  Saginaw 4-speed, Nov 21, 1966
     P8R01  Muncie M2x 4-speed, Oct 01, 1967
     P9T11B Muncie M21 4-speed, Dec 11, 1968
     C9D14N PowerGlide M35 2-speed auto,
            Apr 14, 1969, night shift

In the case of manual transmissions the numbers seem to indicate a year early, but I see in the powerglides it is different.

Safe to say, this is not the transmission that came in my car from the factory.

19Z327173 ?

I wonder what it came out of.

/edit Looks like it possible came from a 1969 El Camino assembled at the Fremont Plant.

Built quite a bit before your car.

I guess it would quite a stretch to say it's original to the car then.

Still amazes me that a factory engine loves such high revs!!

Checking the numbers on my powerglide.

Using the data and examples here - https://www.camaros.org/drivetrain.shtml#trans

T8M22D

T - Toledo Powerglide
8 - 1967
M - August
22 - 22nd day of the month
D - Day shift

Is there anyway to identify the torque converter?

Thanks again!

Streetside Classics is just another group of flippers that will say anything but don't verify anything either.
