SBC Engine casting number
« on: July 19, 2015, 03:34:34 PM »
I can't find this casting number in any of my sources:  3914060 .  There is nothing on the stamp pad.
This is the engine I'm having built for my '68 SS/RS 350.  Can anyone ID it?  Thanks.

Thanks but that's off by one digit. I found that one too while doing research.  I'm 100% certain of the numbers.

That number doesn't exist as far as I know.  Check again.  Sometimes a 6 can look like a 0 if the casting is not clean.  Did you check the casting date and if so what is it?

I know what you're saying.  I'll try to post a pic.  And this week I'll stop by my engine builder's and get the casting date.

Here's a pic of the casting number.  3rd number from the end is in question.  Almost looks like a 3 or an 8 stamped over a 6.  6 would make sense, right?  Pic of date stamp coming next...

Here is the casting date I believe.  A 16 8.  That would be Jan 16, 1968, correct?

Yes, that is the casting date.. It is 'cast in', not stamped (just as the casting number from your prior post). 

Note:  Re your question on the casting number...  NOT stamped..   but CAST in.   Looks like you have a 3914660 block (327) ... just as Byron said previously:  "3914660 is a 1968 block - 2 bolt - used for 327 engines."

Thanks. Appreciate it.  That first 6 looks really funky, especially up close and in person.  Just wanted some of you guys to verify it.  But that's what it must be - a 68 327.   FYI my engine builder just completed it as a 355.  Going in my '68 SS/RS 350. :)
