I need some help with block numbers
 

Hello everybody! I am new here and looking for some help, I have a 3963512 block dated e239--may 23 1969--- there is no vin nubers by the oil filter area and on the front by pass head area there is only a 7 stamped there and nothing else, there looks like there is no deck clearance marks from machine work done, the area has pits in the metal and even has it by the number 7, the 7 is deep enough to catch your finger nail....... So can you guys help me out, thanks Alex from kansas city

Hi, Look on the pad where the starter bolts for any stampings, if it is an over the counter block it will be stamped there, is it a 2 bolt or 4 bolt.

The "512" was a 427 and 454 block used in a lot of hipo Vettes, Camaros, and Chevelles. It should be a 4 bolt block but without the assembly date stamp on the front passenger side pad, it could be difficult to tell just how it was used. If it has two oil cooler line ports by the oil filter, it usually means it's a 4 bolt block.

Hey Alex,

Casting 3963512 with a date code e239 is a 1969 427 block.

Re: I need some help with block numbers
 

Hi Alex, It looks like this is a CE block & it has been decked slightly, the T059 is the assembly date of the engine
May 1969.

Re: I need some help with block numbers
 

What is a ce block?????? as for the decking, it has the same pitting by the 7 , and all over that area, to me if it was decked, wouldn't the pitting be gone???? I know when my 565 race motor was decked the metal had the same type of marks all over, I just would think there would be a difference on the metal between the bare area and the area around the 7.

Re: I need some help with block numbers
 

A CE block is a Chevrolet Engine replaced under the 5/50 warranty of the day. The T059 date code at the starter flange is consistant with this type of component if it was an assembled block and as Jerry said is Tonawanda Month/Year. I dont think that the "7" is really a seven but instead a mark it picked up inadvertantly that looks like one....I mean a seven https://www.yenko.net/ubbthreads/imag...lins/smile.gif The pad most likely had an ole fashioned blanch decking. The code for a CE warranty block from Tonawanda would read something like CE95xxxx if it was still there. Nice block and date pending a tanking and flux regardless.

Re: I need some help with block numbers
 

I would say it is definitely a 7 and was the deepest stemped number in the CE number. The pitting in the deck could be that it was decked 20 years ago and left outside?

Re: I need some help with block numbers
 

SO........Is it worth anything?????? to someone needing a dated block or should I just put it back in the barn and forget about it for another 10 years?????

I thought so too untill I enlarged the photo and could see the definition better. The lower leg is seperated at mid point and that would be a trick with a stamp. I'm not saying 100% since I once found a potato that I thought was the spitten image of my Uncle Wayne https://www.yenko.net/ubbthreads/imag...lins/smile.gif

I have a feeling that you will be getting a few private messages https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: I need some help with block numbers
 

Hey Alex,

The 3963512 in my car is dated D219, just about a month before yours. Yes, it is valuable as these date coded 427s were installed in the 69 COPO Camaros and Chevelles and also by the dealers that swapped them in place of the original engines. Also many original engines were blown up and replaced with a CE block under warranty. Being a CE replacement block should not lessen the value. If it had the original VIN numbers stamped on it, the value would significantly increase if you could find the person who owned the matching car, if it the car hadn'y already been crushed. 1969 date coded 427 blocks are always in demand. As mentioned above, you probably have already received a few private messages asking about a possible sale! Good luck. Jim

Re: I need some help with block numbers
 

No not one yet, but if you guys want I will try to take a pic of the 7 again if need, it looks original to me, and today I also noticed that on the bottom by each cyclinder hole on the oil pan rails it is stamped 7 on most of the holes except the to back I think are stamped number 6???????????? I can do some pics of that to if wanted.....

Re: I need some help with block numbers
 

Hi, The numbers on the pan rail are the cylinder sizes in relation to the piston size, the original fitted pistons had the same # stamped on them as the pan rail.

Someone told this to me a long time ago. I never verified it though.

Re: I need some help with block numbers
 

Hey , what kinda price range are the 69 427 blocks worth std. bore ? Thanks

Re: I need some help with block numbers
 

I have had a lot of input on this,, I have been told it's worth $10 to $15,000 if it had the numbers stamped on the pad, I lot of guy's also said it is what makes the difference on a $30,000 or $300,000 car????????? I would sell it if somebody is needing a may 23 , 1969 block.......
