Anyone know what this is out of?

VO5061CV. And that is for sure what it says. It is a 3970010 block.

if you check the casting date it may help to narrow down your search. I couldn't find that code in what i reference. Also posting a pic might help too. good luck

You are going to have to post good pics of the pad and the casting date.

V = Fliint
05 is May
06 is day of the month.

Here is where is gets squirrely. The &quot;1&quot; almost has to be a letter, not a number.

3 character suffix codes started in 70. So, your assumption of the 70 block is rational.

I don't think GM ever used an &quot;I&quot; for the first suffix letter code, as it would cause confusion with so many &quot;I&quot; characters used in place of number &quot;1&quot;.

Is the pad the early style (long) or late style (short)? 010 blocks were made for about 10 years.

Boats used a number, letter, letter suffix a lot of the time.

Looks like ICV. In my 1970 book all the codes for passenger cars start with a &quot;C&quot;.

I wouldn't even know where to look for boat motor suffix codes. But, Jason may be on the money here. Sure looks like a &quot;one&quot; and not the letter &quot;I&quot;.

Definitely not a 1980 casting, as the pad is the large earlier style.
