Engine markings

[DTrain]

I pulled a motor yesterday out of a '79 k10. I started cleaning it up and found a lot of markings I didn't know were on there. So I'm wondering what these markings mean. Right above where the ID number is, it has the has the GM logo, and next to that is a 37 the same size as the GM. Then from there you work your way around the flywheel and there is what looks like a casting clock maybe? Then what looks like almost a rain drop? Then right past the distributor, the same size as the ID number it has a "G2 9". Then past that the same size as the GM and 37, there appears to be a "S", although it could be a crappy 8. The only things I recognize are the ID number and the obvious GM. I'm curious what the other markings are. Thanks

They are shift markings on when it was made.  Means nothing unless you are restoring a car.

dang, I was hoping it would have led to me finding me pot o gold! Oh well, a good old 350 is nothing to shrug your shoulders at I guess.

Just tell everybody the old saying... that it is a vette motor.

Why not, that is what everyone says.  So annoying...

I must be on the wrong forum, I did pull it from one...

For years and years most cars and trucks for sale with a sbc in them were out of a vette according to the sellers. I was always amazed at how many vettes lost their engines to old pick-ups.

I think the G2 9 marking should be July 2, 1979 casting date.

Look around the timing chain area for 010 and 020 castings to indicate higher tin and nickel content, respectively.

The block that came out of a Corvette means nothing as it can come out of another vehicle.  There wasn't "special" blocks made specifically for Corvettes.  Prior to 1973 (because I am being generous) there were specific components that were used in Corvettes like cams and heads, but eventually these found their way into the "muscle cars".  This is short of the fuelie heads.  If it was anything after 1973, and it was from a Vette, it is no big deal as they were anemic.

I did a decent clean around the timing chain area, not a detail by any means, but I took off the alt. power steering, fan, and everything else in the way except for the water pump(didn't want to fool with antifreeze). Anyway, got to scrapping looking for "010 or 020" as Jason S was saying, and the markings I found were,

Jason S, is the 010 or 020 you're talking about just that plan and simple, or is it encripted in this some how? If this has nothing to do with what you're talking about, where do I find it? And which number would be better?

I know this may be a silly topic I have started, but aside from just education, this motor has 129,000 original, unmolested miles on it, and is a good candidate for the machine shop. Thanks for your input  guys.

It wouldn't be part of a code. 

Under the timing chain cover, there may be a 010 and/or a 020 cast into the block. 

It may or may not be there. If both are there, it would be a 010 with a 020 below.
