Hey SBC guys, please help ID this motor

Hey guys, My buddys dad said he would sell me this motor cheap if I wanted it. He doesn't know the history on it and he told me the guy he got it from said it was a 327 out of a 1968 car. He told me he doesn't know if it's true or not. The casting number is 3970010. Now i've looked at several different websites that list casting numbers and I have found 3 different engines that share the same number. 302/327/350

I've attached some pictures he sent me if this helps.

 

The casting numbers on the cylinder heads (under the valve covers), and the letters/numbers on the small pad on the right front of the block (as sitting in the car), would help to narrow it down. It has a small dampener, so my guess is 327, without having more information. Butch/56sedandelivery.

 

Thanks Butch, anyone else with an idea?

Get those numbers.

 

Yes, it could be any of the 3. 0010 blocks are 68 to 74 car and truck and most are 4 bolt main. There was a rumor that truck 327s with that block had forged cranks, but I can't say it's true. If it's original heads, the 302 would have the double humps, and maybe some of the 350s but no 327s. I think all 0010 blocks were large journal blocks. pull the valve covers and check head casting numbers and the date codes on block and the heads.

 

Are you looking for it to be something specific? Are you going to turn it down if isn't a 327?

 

What's the crank look like on the flywheel end One notch 327 two 350.

 

From the one picture it looks like a large journal crank, but better pics are needed.... also the heads have accessory bolt holes, so the heads are later version than for example 461's...

 

If your lucky it's a 327 with a steel crank or ANY 302. It doesn't look like the valve cover in that one picture is bolted down so have him send you another picture or give you that casting number and post it right away. those numbers/letters on the fromt pad will help alot as well.

 

I checked some of my stuff and the heads could have been either with acessary bolt holes or not and the engine could be '68. I have a set of 3927186 castings that are the accessary bolt style ( available 68-72 ) and also a set of 3917291 with a date code of aug 27 67 which would be '68 production.

 

All that 010 number means is that the block has a higher nickel content in the mix. Good block. That same number is on my SBC 350 in my race car

 

The 010 refering to the nickel content is behind the timing chain.

 

Lots of really good advice guys thanks. I am getting the motor, I figured I can't go wrong with any of the three, I just wanted to find out which motor it is.

 

010 blocks were made until at least 1981. The 010 blocks were usually 350s and either 2 or 4 bolt mains. They were not 400s and the 020 block was a 305 and usually 2 bolt mains. The 010 behind the timing chain is a core designation for the 010 core set used to make the block. If the 010 looks like the 010 on the back flange it is only a casting number. The real helpful number would be the casting date pad number also on the rear flange or the stamped number on the vin pad. Small journal 327s were not 010 blocks. As I remember.....

 

If this is what the flywheel end flange looks like it's 350. The one on the right is the ealy edition. Like sunbeam said the 327 has only one notch. The 302 is almost round.

 

I probably would get it also, but if it's already .060" over with worn cylinders, it's not worth much.

 

Just a quick update, the pad on the front says v0819cks. I believe the heads have been replaced over the the years. It has 882 heads which I believe is a newer head.

There is also another number on the front that says 16n505586.

Quik search appears CKS is a 350 of '72-3, or '77 vintage.

The nine digit number tells me (and you) that it came out of a 1976 chevy.
The "1" stands for chevrolet division. 2 is pontiac, 3 is oldsmobile, 4 is buick.
The "6" is the model year (1976 in this case)
The "N" is for the assembly plant where the car was made, but I admit I don't know where (maybe Norwalk,OH.)?
The last six #'s would match the last six #'s of the donor cars V.I.N.
Oh, and if it had come out of a chevy truck, a "C" would replace the "1"
Since it's a '76, it has to be a 350 with that 3970010 casting number.
My engine code book only goes to '75 ,but it wasn't uncommon for chevy to use the same codes (i.e.CKS) in different model years.

For what it's worth, Ron.

 

I might be an exception, but I've never seen a 4 bolt 010.

 

Well that's disappointing, I was hoping it was a 60's 327. At least the 0010 blocks are desirable

can not find info to figure out a small block Chevy with this stamping on passenger right front: 19C154946

 

I believe that is the partial vin code of the vehicle the engine was originally installed in.
There should be another code stamped on the pad which is letters and a few numbers.

 

I have 7 in my shop now & have built hundreds. Most 350's with 010 casting numbers that were installed in 4 WD or 3/4 ton & up trucks were 4 bolt main.

327 large journal forged steel cranks were used in 1 ton & up with 4 speed truck trans. This seems to be the only place I have found them.

010 behind the timing cover by itself just means core set, but when found in tandem with 020 this means high nickel & hi tin, and can sometimes be found on the rear and not behind the cover.

 

Doesn't matter, Tell everyone it's a 327, no one's going to know the difference except you. There is no replacement for displacement.

 

I wouldn't put any $ into the 882 heads, got a car for this to go in, orare you gathering parts?

 

This has been discussed endlessly on many sites and no one has ever been able to document it.

 

I have an 010 motor sitting in my garage that is complete from carb to pan. 650 Holley on it, Edelbrock performer, Ram horns, etc etc. But its only a 2 bolt main. I can't get anybody to give me $250 for it.

 

For what is in the pic, I would gladly pay $400 but your in the wrong place - NJ !!
