My car is a 68 350 TH400.

Waiting on more parts so I thought I would hunt down some numbers to see what I have. For the engine, I found a few numbers on the block but I could not find the typical double code. I did find the one number listed in block casting numbers chart. They appear to be used for 327 and 350 in 1967 models.

Question: Does that mean this motor is out of a 67, or are the blocks widely used across other models and years and 67 just happened to use these particular blocks?

Is there a way to tell if it's a 327 0r 350?

Found a tag on the transmission left side up on the bell. I could find nothing that looked like the numbers I found on tranny tag. Any info would be appreciated.

Found numbers for exhaust manifolds. Is there a way to identify numbers on exhaust manifold?

Any info appreciated. Thanks

Yes, the block is a 67 (cast on February 1st, 1967) but unfortunately, it's been decked so there's no way to know what it was originally. However, if the engine is out of the car you can check the crankshaft flange and that'll tell you what it currently is (see below).

Excuse my ignorance, still learning here. What is decked? Also, so that means does that mean this came from a 67 Camaro, or that it is a possibility it came from a 67 Camaro?

Thanks

Decked means the engine block has been machined down as shown in THIS VIDEO. This is typically done when the engine is rebuilt.

Cool video. So maybe my numbers were at front passenger but were filed off during the rebuild?

Maybe someone out there knows about this car? Any history?

It is a 1967 small block engine but it could be a low horsepower 327 and those did not get VIN stamped on the front pad.

Clean off the pad with some lacquer thinner on a rag, take hi resolution pics and email them to me at bcm66@cox.net and we can determine for sure if it has been decked. I am not convinced but it may be the case.

Corrected to add “VIN”.

bcmiller · « **Reply #14 on:** July 22, 2022, 06:10:34 PM »

Well it says right in the ad that it is an SS 350 tribute, so it is probably not originally an SS 350 car.

And only big block equipped 1967 Camaros with the 396/325 hp engine got the TH400 transmission. 1453 produced.

C'mon Bryon. It should at least have the suffix code! You know that!!

His car is a 68, so 5,466 Turbo 400 transmissions.

And no, the car's not in the database.

Thanks Bryon. Yea I know, I have a hodgepodge of different items on this car. That is why I am trying to get more info on where these items originated. I can't even be sure it's a 350 in there with out more info. I will clean and send picture.

Thanks

We will see with the new pics. Play along Ed.

A 1967 CE engine would NOT have anything stamped on the pad in most cases.

And those were not decked. I am not convinced this one was decked, yet.

I disagree with that statement, but I'll let you take the wheel.

CE stampings started in about late August of 1967 for the 68 model year. Many examples of blank pads.

bcmiller · « **Reply #21 on:** July 22, 2022, 07:08:42 PM »

Train wreck, I need to stop responding by tiny phone screen.😳🥲

I was going by the engine casting date! B 1 7

If it was a CE engine from that time, it would NOT have gotten stamped. End of story on that. If it was a warranty engine, there will be some information stamped on the underside of the starter mounting pad area with the assembly plant, month and year of assembly but that's it.

I can't tell from the pics if it was ever stamped or if it was decked and modified. Doesn't matter.

Bottom line. Engine is not original - it's a 1967 engine in a 1968 car, so no go. TH is not original - those were only installed in big block Camaros from 1967 to 1969.

Engine not original. No big deal. My engine is not the original one to the car either.

Chuck-68-Cam · « **Reply #27 on:** July 23, 2022, 12:12:32 AM »

Yea, I knew when I bought it that there was not to much original on it. I am good with that. I am just having a good time making it better than when I got it.

Chuck-68-Cam · « **Reply #28 on:** August 08, 2022, 05:16:29 PM »

Today I found this set of numbers by the filter. Do they tell us anything? I did not see these anywhere in the guides.
