Brandon,
In Corvette By The Numbers 1955-82.
I found a reference to CLA in the Suffix Number
Usually these letters would be found after the Stamped numbers.
Example: 000000CLA

1973 Engine Code Suffix Identification
Engine Horsepower Transmission, Options Suffix
350cu. 190 Turbohydromatic 400 CLA

1974 Engine Code Suffix Indentification
Engine Horsepower Transmission, Options Suffix
350cu. 195 Tubrohydromatic CLA

Quoting Bill Clupper: Get the GM Casting and Cast Date Code Numbers off the back side of the Block. GM Casting Numbers...back side just under
the head...Drivers Side
Cast Date...back side just under the head...Passenger Side.

It shows a block number: GM 3970010
1969 to 1979 Corvette 350cu. w/various Horsepower and Mains.
This might help you???

As for the X letter, they may be right....1968 Playboy Limo

Got the number off the drivers side back of the block it is: 3959532

couldn't see the date good enough to make it out I'll get it later. That help any?

Re: here is the engine pad number off my 58..what did the engine come out of?

3959532 was primarily a '64 283 block, also used in some CE replacement engines.

That's a 283 block, but I don't know what the usage was; the pad stamps don't meet any known factory format - they're probably a rebuilder's code.

Re: here is the engine pad number off my 58..what did the engine come out of?

Yeah, I know John..that long vin looking number is weird! not sure about the B numbering under it tho that looks factory to me.

[Brandon T.]

Re: here is the engine pad number off my 58..what did the engine come out of?

the date code on the passenger side back is D280

[William C.]

Re: here is the engine pad number off my 58..what did the engine come out of?

It looks most likely it was a service engine or shortblock from 1960 era.

Brandon,
Bill Clupper is right about your cast number.
A friend of mine looked at numbers on the Internet somewhere and
your block number GM 3959532 is listed as a short block for the
years: 1956 to 1967 283cu.
Cast Date Code D280 = April 28, 1960
Who ever stamped the the front boss is probably the only one who
knew what it meant.

I was supprised to see that the GM # also included the 1956 year
as a 283cu. motor. I wasn't aware that there was a 283cu. in a 1956
Passenger car or a Vette.
I knew there were 265cu. and 283cu. motors in Passenger Cars in 1957.
!957 Cars were in the Dealerships in September 1956.

Of course GM usually brought all their New Models out in the previous September of every year.

The 39595XX series castings came out after small journal blocks were no longer being used in production vehicles. They were part of the CE replacement engine/short/fitted blocks to service the 67 and older small journal engine needs. They are usually found with CE codes and I believe they began in 68 so I suspect the date code you provided is 1970, not 1960.

3959512 regular small journal 327
3959532 regular small journal 283
3959534 Chevy II small journal 283 recessed oil filter
3959538 Chevy II small jlournal 327 recessed oil filter

Cecil,
What my friend brought up on the Internet showed a bunch of
GM numbers and what they applied to.
It showed GM 3959532 as 56-67 283cu. I don't think it said anywhere that they were produced in 1968.
I assume that CE means Corvette Engine?

I'l try to find out tomorrow where he brought the info up on the Internet.
I didn't pay attention how he got into it. I did read it on the screen.

Karl,
There are a lot of references out there that are rather general in application and lacking specifics. Mortec is a fairly good example. Many simply parrot what some parts crossreferences list for application without considering what its specific application is and with many errors. The 3959532 would , in fact service any small journal engine from 55-67 but was intended to service 57-67, since those were the years for the 283 engine in factory application. After 67, the small journal engines were no longer being produced for installation in production vehicles but GM still needed to service the engines to support the warranties still in effect as well as other service applications. The large journal engines could be retrofitted to work, but it would involve some changes to the original application configuration especially in regard to the crankcase vent system. I'm sure there were other considerations, but I believe those are the most obvious. I don't fully understand why they didn't just continue using the last (67) casting numbers for service blocks, but for some reason they issued these new casting numbers for the replacement small journal blocks and I'm not aware of any casting changes other than the number itself.
Maybe John Hinkley or some of the other more knowlegeable guys can explain it better. My research into this came about as a result of the 69 dated 3959538 CE 327 350hp L79 engine in my 67 Nova which, I believe was installed under warranty. I also have a CE 3959532 casting 283 in my 58 Corvette. it also has a 69 casting date. I have pics of an NOS 3959534 Chevy II crate longblock with perfect inspection paint markings on the bare casting.
There is more info in previous threads on the CE engine program.
