CE Block

[Robert D.]

Looking at C2. Owner says it has a CE Block. What does this mean?

Re: CE Block

From what I understand it means Counter Exchange block or replacement.

Re: CE Block

Yes, it is an over the counter replacement block. If you do a search here, there have been previous discussions on that subject.

Re: CE Block

Do a search and you'll find that "CE" stands for Chevrolet Engine. I know, I have one. John Hinckley posted on this subject and clearly explained why they were stamped "CE".

Good Morning

I searched and only found questions about CE blocks. Can you direct me to the response you reference by John Hinckley, please?

Thank you,

Quoting from the Chevrolet Dealer Service Information Bulletin, 69-I-1, dated 19 Sept, 1968:

The following system will be used to identify service engine and transmission assemblies* including replacement parts. Manufacturing plants will number each assembly as it is produce. The first letter will designate the GM division which produced the engine. C-Chevrolet L-Oldsmobile K-Cadillac B-Buick P-Pontiac The second letter will designate the type of unit "E" engine or "T" transmission. The number following the letter will designate the model year "9" for 1969. The last five digits specify the service replacement unit sequence number. The group of numbers to be used by Chevrolet manufacturing plants are as follows: Engines Flint Motor Plant (L6 Engines) 00001 to 19999 80001 to 89999 Flint V8 Engine Plant 20000 to 49999 Tonawanda Motor Plant 50000 to 79999 Example: Number CE900175 designates Chevrolet engine - 1969 year, and the 175th unit produced for service at the Flint Motor Plant (L6). Transmissions Cleveland Transmission Plant 00001 to 14999 Toledo Transmission Plant 15000 to 24999 Saginaw Transmission Plant 25000 to 34999 Muncie Transmission Plant 35000 to 44999 Hydra-Matic transmissions will be numbered with the letter "H" regardless of the G.M. Division using the transmission. * This numbering system applies to service engine assemblies, partial engines, fitted cylinder cases, cylinder cases, transmission assemblies and transmission cases.

Re: CE Block

Thank you, Jim! Very helpful. It almost sounds like this could have been an honest exchange by GM. What are the thoughts out there about a car's value if it has a CE block?

Re: CE Block

It's still a non-original engine.

[Michael W.]

Re: CE Block

The E is for engine not 'exchange'.

[Tim G.]

Re: CE Block

Not original and most likely dated past the build date of the car. For example, if a '67 Corvette was built in June of '67 and received an engine replacement under warranty in January of 1968, the casting date and number could be for an engine better suited for a 1968 model year Corvette. I'd rather have a correct casting date and correct casting number on a block than CE replacement.

Re: CE Block

True! (Although I wonder how many C2s have an all original motor by this point in time?) Good point, Cecil!

[Robert D.]

Re: CE Block

Thanks, Tim. I agree. Those are things I will need to check for. I think I am going to pass on this one. I really appreciate everyone's input! Really important!
