Suffix Codes & CE replacements

[Mr70]

The first digit "1" in this case would be the only indicator to the service dept.,as well as it's casting number & date.
They would reuse the Heads & Intake and other exterior ornaments from the original block.They only replaced what was damaged,so that makes sense.
I know of a few LS-6 Chevelles that were replaced with 1972 2 bolt #290 blocks,as well as a few 1969 396's camaros that were replaced with 454's.The customer/service dept. would upgrade,or downgrade in some cases with costs accordingly.
I can not comment on this list Fran is referring to.

Back in the late '60s a local dealer was swapping 427s for 396s when a warranty engine was needed. The story went that GM eventually caught up with them and dumped them as a dealer. I've heard other stories of such trickery as well.

I restored a 69 L-89 corvette 17 years ago it was serial 4427 (hard to forget that #) and it had a 427 CE block dated july 69. It was a 4 bolt 512
Another corvette I have done was a 67 435 and it had a 72 dated 454 CE stamped block. It also was a 4 bolt block, however I don't recall the casting #.

So Keith....what you're saying is the dealer was purposely putting the 396 in place where a 427 came out (not the other way around) and how would this had been any advantage to the dealer if they ordered the motor as a warranty replacement item anyway? . Did they perhaps try this on you when you got your CE motor? . Lastly, isn't it you that gave me the Arctic EXT cyl. a few years ago? I'm here in Peterboro'!

from the April 69 Service Bulletin

No. The guys were abusing their 396s to death and the dealer was replacing the 396 with a 427 under warranty. Made for loyal customers while it lasted. I'm the same Arctic Cat guy. I still have a 1972 EXT brochure. The CE engine was in our 396 car when we bought it and the original owner confirmed having dropped a valve while the car was under warranty. Our COPO car has its original MQ engine. We just took the body to a local guy after having it sit at another place for almost two years. Patience ran out. Might have it out next summer but I gave up holding my breath. We'll see.

Outstanding document!
Wish this was presented years ago!
Is there any additional service bulletins prior to and after this released document referring to any replacement issues regarding warranty(s)?

[PeteLeathersac]

Great stuff....thanks Hawaii! . So Keith....what a friendly dealer offering basically a 67/68 Yenko at the General's expense! . Would one of these 427 cars now be considered a dealer installed option....just kidding, I think? . What was this magical dealer's name....I'll keep a lookout for his tag? . And thanks again for the EXT jug....I let my EXT also a few other racers go a few years back now but still have quite a few SkiDoo factory racers....early Blizzards and IFS plus a few others. . Have a great weekend! ~ Pete

Hello all, new to the board. I have a CE code shortblock, and just went out and looked at it (3:16 a.m) and here is what I have. The block casting is 3959512, it has a 1182 forged crank, pink rods, and standard bore. Date code of K149, and the stamping is CE9A93177. As far as I can see that does not fall within any numbers that are listed on that 69 Bulletin. Anyone have any input. I have had the engine for about 3 years, and it had a Corvette pan on it when I got it. Thanks Kevin

I wonder what the "A" (the 4th charector) in the CE9A93177 is for? I also wonder why the number is to high to fit into any category on that 69 bulletin.
