Re: Non oem 68 SS Chevelle engine ID CE block journey

Ok

Block casting date , passenger side near freeze plug / motor mount area.
These are cast in .

MAN THEY ARE ROUGH AND HARD TO READ , and upside down .

Q 14 8 Again super ruff cast in , not super positive about any of them .
Sorry.

Engine assembly date , starter pad . I assume they are stamped in.
Still cannot find stampings , on the starter pad or surrounding area. I will have to pull the starter to get a total view of the area. Not a huge deal , except I was stupid enough years ago to run the new trans cooler hard lines under the starter trapping it . Arrg.

Thanks all

Re: Non oem 68 SS Chevelle engine ID CE block journey

There is no "Q" month, probably "G" for July.
Here's a sample of the warranty engine date stamp.

In post # 15 you mentioned getting the cyl head numbers.Remove the valve covers and the head #'s will be around the middle of the cyl head while the heads casting dates will be between cylinder # 5 and 7 or 2 and 4 on the other side that's IIRC.

So knowing what we know about the block .
Did these heads come on it
Or
Did someone put really good heads on a lower performance block

Hmm

Re: Non oem 68 SS Chevelle engine ID CE block journey

Here's the information listed from the out inthe shop web site.

3935439---427---68-69----2 & 4-Bolt

If you have the tapped fittings above the oil filter more than likely it's a 4 bolt main but the only really sure way is to look inside the oil pan.

Re: Non oem 68 SS Chevelle engine ID CE block journey

Soo just to re cap and consolidate all these numbers .

Front Engine ID Pad CE950409

Back of engine :
3935439 Block casting #
G 14 8 Block cast in date
***** assembly stamped in date not found yet

Cylinder Heads
Hi Perf
GM4T
3919840
F18

Engine has a solid cam . Type or manufacturer unknown.

Only one oil pressure tap off , right above the oil filter. Most Not all 4bolt main blocks have 2 OP tap offs for an oil cooler .
My recollection of seeing / finding it was a 2 bolt main cap block Many years ago while changing the oil pan

Soo 99% of the info has been gained , with all your help.

Ill Never know what car model this CE block was installed in . A shame , i wanted to know.

To me all this info boils down to this
I have a 427ci , 390 or 400 Hp 1969 block that someone put 1968 good squareport iron heads onto.
Open to opinions and corrections please

thanks 24hrsparkey
