CE Block

Re: CE Block

If you were to look into it further I think you are likely to find that the the last three digits of the block casting number are 512 rather than 870 if it is a small block car. The 512 casting cylinder case was only used to service replacements for the no longer produced 327 when the CE program began in 68 or 69.

To confuse the issue there was also a big block casting number ending in 512 that was used in production somewhere around late '69 to transition from the 427 to the 454 for 1970. The 454 required more cylinder wall clearance.

Re: CE Block

My 1970 Corvette is a original owner bought new from the show room floor of a Chevrolet dealership.
It has a CE engine short block because the original engine did not last 10 minutes driving from the dealership. I have over 150,000 miles on the replacement engine.

Re: CE Block

So maybe having a CE block is not necessarily a bad thing.
Thanks, Jim.

Just a guess and JMHO>Small Blocks 65%---Big Blocks 35%>Comments? Larry

This would be an interesting factoid to know, if it was knowable.

Judging from eBay cars for sale, it seems virtually 100% have their OM.

It's not as good as having an original engine. But, it's way better than having a Pontiac engine.

I would guess less than that.

Re: CE Block

I have a CE big block in my 67. I don't have the #s in front of me but the casting # said it was a late 67 early 68 block. I will have to get the #s off
the pad and date off the engine.

Robert,
I would like the guys that posted a answer as the group here on your thread to see what they think as this block had CE on it in 67, but obvious for a early 68.
My CE Big Block is 3916321 which says late 67 early 68. H 15 7 = August 15, 1967. From what I can read on the pad
is is CE 51463. Doesn't make sense.

Actually it does make sense if you know what blocks of numbers were assigned to which engine plant. We placed the Chevrolet Information Bulletins with those numbers in the chrome bumper C3 TIM&JG in the earlier editions, but we have been told we are no longer to include those as new editions are produced.

So it is. Mystery solved.

Re: CE Block

Thanks for post #6. I am missing a number on my pad. I will have to look harder as it should be a 7 or possibly a 8 following the CE. CE ?51743

Re: CE Block

Thank you, Robert! 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?

Robert

Since you are asking these questions on the NCRS forum I am assuming you are looking for the best block for your car for judging/value. Most CE blocks have the wrong casting number and date to be anywhere close to being correct for your car. Judging allows for the least number of points lost when the original engine is gone, with a date code correct engine with the correct casting number block built in the right plant for your car and the time your car was built.

Re: CE Block

The program actually began before 68 with the CE numbers being stamped on the warranty and service replacements using the current production blocks before they stopped using 327's in production. After the small journal 327 was out of production they cast the special retrofit replacement blocks :
2959512 car and truck 327 both small journal and journal
3959532 car and truck 283 SJ
3950534 Chevy II 283
3959538 Chevy II 327

Most online sources mistakenly list these implying that they were used (cast) for 62-67 production but they were for service replacement application for out of production engines/blocks.

Re: CE Block

REF my previous post above my CE engine has CEOA 47538 on the block front engine pad. The rear of the engine block on the drivers side has 3970010 and the right side rear of the block has D 26 0 stamping.
