512 small block??

[iluv69s]

I picked up a small block chvy motor in a package deal..it is a CE stamped block...

It is cast number 512 I believe...seems like a 1960 or 61 cast date ? I believe L-8-0...or could it be 0-8-7 ?? has to be a 61 block, correct?

With a 4" bore?? would that be a 283 ? The motor is not here in my gar yet, so I am going by memory...

did they even have CE blocks in 1960

the 1st 4" bore Chevy small block was the 62 327 ...

283's had a 3.875 bore ...

what is the size of the front pad?

Must be a 70 block. They were not stamping engines as CE prior to 1968. Is it a large journal block or small journal?

From CRG

The 3959512 casting was mainly used for warranty / service blocks. It is a 4" bore block, thus could have 302, 327, or 350 applications.
