Hey Folks
I'm working on the 350 in my T-Bucket,the guy before me built it into a 383. I'm looking for the numbers on the block and not having any luck. The block has been decked so the ones in front of the head are a wash. So next place I look is behind the drivers side head where the numbers should be right next to the GM letters nothing, just says, GM LV57 I'm lost why are there no casting numbers here?

Next thing is on the timing chain cover,theres a gasket,a thin metal plate looks like shim material,another gasket ,then the block. What is this extra peice for ? Thanks Folks

You should have a set of numbers just like this block, behind the drivers side head. They are there, unless ground off for some reason. Maybe caked with paint?

I don't know why they would put a spacer or shim on a timing cover, unless it was an old style cover and a double roller timing set had clearance problems.

Little bit wrong on the numbers but this is what I got behind the drivers side head.

Later model block. Check if Heco en Mexico. The oddball timing cover is an aftermkt two piece for easy camshaft change. Leak like mad.

most likely what u have is a 2 pc timing cover.. that so u can do a cam change without droping the oil pan... in a tbucket if u ever decide to change cams u'll love that item.. i done a few changes on my bucket and finally did the 2 pc... nice !!!!!

Geez, the way it was explained, being "shim" looking, I was thinking something in the thousandths of an inch thickness! Make sense now...

Thanks folks,thats what it is,a Edelbrock two peice,never saw one of these before.
So Racer if I have like you say a ,"Made in Mexico" block is there anyway I can find any info on it,HP,year, anything ? Its a 4-bolt. Should there be any numbers anywhere else that I can look for ?

What difference would it make?? If it has been built into a 383 any info you could find would be meaningless anyway.

The "187" is a date code, either 1987, 1997 or 2007 date.

You know it is a 350 4-bolt block late model , having then been built into a 383 stroker. The block is the only likely remaining factory piece.

How true,I guess it's just mind boggling to not see the numbers,LOL many thanks to everybody. Like you screen name Eric.
