Default Engine Code Help: C-3A427 63

We think that's what is says, but we can't be sure. The "-" is high, like a T or F and the 3 might be an 8. But A427 and 63 are very clear and the 63 is bigger and separated from the rest.

Casing is 3970010

HELP!!!

010 is going to be a 350, and probably a CE replacement motor.

That's a block used from the 69 through the late 70's in many SBC applications ( 302,327,350's). Unfortunately it definitely didn't come out of a 63.

Casting number puts it as a very late 60's to early 80s, 350 cu. in. most likely although a few were 327 in '68.

Got a picture of the stamp pad? Could it be CE3A427 63? If so, it might be a factory crate engine from 1973.

That's not a GM stamp. Could be the machine shop who worked on it stamped it for there use.

Although the pad surface itself doesn't look reworked.

I don't know. "427" and "63" I guess? It's a wikipedia entry I learned. Just posted it for discussion.

Well - from the photos the heads are still on the engine. If a 409 based block that should be fairly distinctive enough but there is no mistaking a 348/409 head for a SBC.

lets start with the facts the 010 block is a 350 block cast from 1968-to some time in the 80's. it was used in millions of cars and truck. they sold hundreds of thousands as over the counter blocks with blank stamp pads. if you locate the casting date on the the blcok. that is on the other side of the flange where you fond the casting number. that will narrow it down.

if you ever look at factory stamp pads you will notice that yours looks nothing like them in any way shape or form. that leads me to think that your motor was built at a local machine shop. and some shops will stamp a the pad with numbers so they can keep track of it if it ever came back to the shop.

Looks to me like a "CE" 350 built in 1973 at Flint V-8, in the second round of the re-assigned block of numbers for that year; the "42763" fits in that block of numbers. It's very common for the last two digits of the second round-reassigned number to be stamped separately.

This makes ALOT of sense. The car was purchased in '72 from the original owner's family. Installation of a new motor shortly after that is definitely possible. The more I look at the stamp, the more it looks like a "CE." How do you know it was built in 1973 in Flint--3A? Anything else I can tell about the engine from the the other numbers (42763)? I've googled the topic several times and found the nastyz28.com site useful but not for my particular engine.

THANKS!

All the "CE" stamping will tell you is the year of manufacture (1973, in this case), and the sequence number fits in the block of numbers assigned to Flint V-8. "CE" short blocks were ordered by part number to match the original engine's configuration, but that part number only appeared on the original paperwork and the shipping crate, not anywhere on the engine.

AGAIN, Great information, thanks! So all I can tell about the engine in my Vette is that it's a '73 crate 350 engine (possible warranty replacement for some other car) made in Fabulous Flint, MI.

Might have to move "engine replacement" up my list of things to do!

Of course, it is a very strong-running motor and my dad who put it in was a drag racer back in the early seventies when he bought this car, so maybe it's good engine, just not era-correct.

Looking more and more interesting.

When time permits, please take a look at the numbers on the transmission and see if it matches the DZ engine numbers.

Nice toy you got there, enjoy.

Alas, it is not the Z28 transmission.

3851325 is the main case casting number. But it might be the OEM transmission from my Aug '63 Vette?!?!

Research suggests that it's a '64-5 Muncie, but I've got other parts in the car that are '64 specific because it was built the last week of '63s (i.e., the seat belts are '64s).
