How to read a CEA stamp
« on: February 12, 2019, 10:53:14 PM »
Hi everyone, I just got this block 010 4 bolt main 350 dated L-18-0 and it has a CEA126522 stamp. It was suppose to be a 350/330HP from his corvette. How do you read these numbers  and are the number suppose to look like this ?  Thank you  Emo

Read this thread - CE discussions have been around the block a few times (sorry for the pun) -

Read the links...   but based on the information you presented, it is *possible* that the block was a warranty replacement (short block) for a '71 LT1 engine (but apparently it's missing the internals if all you have is the block?)..   No way to prove it, especially without the internals...

It is a 1971 Flint warranty or over the counter block.  No way to tell what it was originally, as far as I know.

I have the internals.It has a forged crank that looks like its been nitrated ,186 heads, I think the rods were o, the pistons look like the same as a 302 probably 11:1 solid cam. I was thinking it was a LT-1. The guy had the aluminum intake and Holley carb but wanted to keep them . I sent out the heads to be burn blasted and magged . 1 was cracked. I read through all those links and now my head hurts lol. I am going to see if he has the paper work. Thank you for the help. Emo

Also, what are the dates on the 186 heads? If replaced as a short lock, the heads would be original to the car.

Thatís a good 350 crankshaft. If it checks out, use it.

If you get a chance to have a look, I'd like to know if there's anything stamped on the oil pan rail near where the starter motor goes. Been following that info, which is possibly the date of machining/assembly, to see how it lines up with block casting date.
