Re: CE Block
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,

Re: CE Block
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
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.- Top
