Hi All,

I'm fairly new to the forums .. just got my '67 RS project about 2 weeks ago and have started dissambley. I'll probably start a thread in the 1st gen forum with progress, pics and all. The person I bought this car from was well ..... a tool, possible dishonest butmore about that later. He told me this was a 1967 327 motor. Let's see. I've tried some decoding on my own from camaroresearchgroups web site and found out 1 thing but i need a hand w/ all the #'s.

Here's what we've got:

block date code appears to be K2T8 ... does that mean Nov 21st, 1968 ?

the GM block casting # is 3959512 .. which on Camaror Research Groups web site say: 'Also, there is a 3959512 block that has been found very infrequently in some 69 Camaros. Not much is known about usage of this block, but it is a 4" bore block, thus could have 302, 327, or 350 applications. '

the engine id/vin # looks to be CE 943938

So is thisa '67, '68 or '69 enginge?

Let me know what you guys think. Thanks a ton.

This should be easy. Are you sure the K2T8 isn't K218? That would make it Nov 21, 1968.
The "CE" in the code stands for "Chevy Engine", which means you have a Chevy replacement block, not an original.

 

Hey Camaro 69,

Thanks for the info. I can't tell if it's a T or a 1. It does look like an upside down 1. Also the last number is slightly mangled ... can't tell if it's a 8 or 3. From http://www.chevy-camaro.com/chevy-ca...gine-codes.aspthey show:

Engine Block Codes for CID 327
Casting Years CID HP Main Notes
3959512 1962-67 327 2 Was also used for some replacement blocks

The heads have # 3884520 on them .. which that same web site says:

Heads Casting No Years CID Intake Exhaust CC
3884520 1962-67 283/327 1.72 1.5 60.530


So if that last # is a 3 .. from the engine date code, i guess that makes this a 1963 327 motor?

Ok here goes lol. First off there is no 3959512 casting on a 327 or any other block from 55' to 93' year model. The castings for 327's are as follows:

62'-65' / 3782870 and 3789817 corvette,passenger,chevelle,and truck all small journal blocks

65'-67' / 3791362chevy II and nova recessed oil filter boss, small journal

68'-69' / 3794460 passenger,chevelle,camaro,nova Large journal

64'-67' / 3858174 passenger,chevelle,camaro,truck small journal

66' / 3858174 same as above but also includes 300h.p. corvette block still small journal

64'-67'/ 3858180 passenger,chevelle,camaro,truck small journal

65' / 3858180 corvette block

64'-67' / 3892657 passenger,chevelle std. and high performance small journal

64'-67' / 3892657 truck small journal

66'-67' / 3892657 corvette 300, 350h.p., small journal, 2 bolt main

67' / 3892657 camaro, Z28 small journal, 2 bolt main

64'-67' / 3903352 passenger,chevelle,camarosmall journal

68'-69' / 3914660 passenger,chevelle,camaro,truck,nova

68' / 3914678 camaro,Z28 large journal, 2 bolt main

68' / 3914678 corvette 300, 350h.p., large journal, 2 bolt main

68'-69' / 3914678 passenger,chevelle,camaro,nova,truck

68'-69' / 3932386 passenger,chevelle,camaro,nova large journal

68'-69' / 3933180 passenger,chevelle,camaro,nova,truck large journal

68'-69' / 3955618 passenger,chevelle,camaro,nova large journal

68'-69' / 3992386 passenger,chevelle,camaro,nova,truck large journal

That is all the Chevy 327 block casting numbers.
Plus all the chevy block casting numbers there are there is no match for your number you put onthe thread so it is not a factory block.

As for the heads the number is right #3884520 is heads for 60'-67' / 283 and 327 engines but they go as follows

60'-67' / 283 truck

62' / 327 corvette

62'-64' / 327 passenger

62'-67' / 327 truck

64'-67' / 283 chevelle, nova

None of the heads with that number came in a camaro

Hope that helps for now and sorry it's so much info. lol. The more you get in the motor let me know and i can also check crankshft and other casting numbers.

 

Aaaaah...but yes there was, grasshopper:
"3959512, 1962-67 327. Was also used for some replacement blocks."
And since the block has the "CE" (Chevy Engine) code, his is a replacement block, with that casting number, which does exist.

lmao if you were to read all the post before you answer!!!! I also said not a factory block. As in not matching numbers so there for the motor makes the car lose value not gain value. As for the "CE" = chevy engine really do you think? lmao. He did say it was a"Camaro" right? Then it should have achevy engine right?Besides a casting number is used on alot of different motor sizes but have the same casting number. I can't see it right now but i believe he said67' Camaro. In 68' camaro and Z28 models the 302,327,and 350 all have the same casting number-3914678 which is also used in 327c.i.68' corvettes, 68'-69'passenger,chevelle,camaro,nova,and truck, and also in 68'-74' 350c.i. passenger,chevelle,camaro,nova, and truck. Then 69'-76' 350c.i. truck. So there for "GRASSHOPPER" block casting numbers only help so far then you have to do more research and motor breakdown. So here is proof. Let's say for example i have a block casting number that is #3914678 what engine do i have? The answer is you don't know yet "GRASSHOPPER" i could have a block from any of the cars listed above and year model from 68'-76' and anywhere in between. That is why i said he could p.m. me or just repost more info. on the engine and i can narrow it down. Thanks for actually reading this time" GRASSHOPPER" if you read this far.

 

Do a little more research, you might be limiting your info to only one source? And I do know you said it isn't a factory block, that's why I said it is.
You also said "First off there is no 3959512 casting on a 327 or any other block from 55' to 93' year model".

But there WAS a Factory block with that casting number available for 1962-67 vehicles, AND was also used as a Replacement block.
The "CE" designation is a code that is stamped on the Front Pad, along with the partial VIN#. The "CE" stands for "Chevy Engine", and that code is used on REPLACEMENT BLOCKS only.
There would have been a 3959512 casting block in a matching numbers car, just not in his since his block was used as a replacement.
And by the way, yes I do know that having only a casting number will tell nothing about what model car it came in. That's what the prefix code on the front pad (other than CE) will tell you.

 

Hi all, I have a 67 chevelle 327, the number on the front of the block by water pump reads 81 663784 0. What does this mean? I have searched and searched but no luck. Please help
