The photo needs to be in a format that the forum understands. A .jpeg is the standard and most common.

Put the photo on your computer desktop and name it something obvious. A lot of times I will temporarily name a photo "AAA000" so it's easy to find if I need to search for it.

Make a reply here to this message. Above the text field you will see a row of icons. One is a smiley face. The next one is a paperclip. The next one is supposed to look like a photograph. Click that. It's the 'Upload' icon.

A new window opens. Click the maroon bar that reads "browse your device". You will see a new window that shows the file structure on the computer. It should default to the desktop. Scroll down until you find the file. This is why I name a lot of things AAA000 at least temporarily Find the photo, double click it.

The image will load into the upload screen. Might take a minute. When complete, click 'upload' in the maroon tab at the upper right.

The image will be inserted into your forum text field, just as if it were text. Click 'submit reply' in the forum message window as normal, and the image is posted here.

How certain are you the block is an original L79?
I ask because late 70's early 80's Corvette blocks were blue.
Any chance this is one of them repainted orange?

my 67 L79 has a replacement block, but it’s the correct casting for 67 (still has the valley vent), and a 1967 casting date.

but the “ GM Corporate Blue” is visible on the block and oil pan… with orange flaking off…

Yes. Over the years I have seen blue come through on orange engines. Not too unusual.
Thats why I asked the OP how sure he is about his L79 engines originality.
Could be he has a blue engine painted orange and the blue is peaking through.

Are you just now noticing the blue paint? You didn’t notice it back in 67? If you are the original owner and it’s the original engine, then that’s all that matters. I mean it could be the paint shop grabbed a can of the blue instead of orange and said oops. Well it’s 4:30 on a Friday, just leave it, I’m not mixing up more orange.

Looks like a blue painted block to me.

I ordered the car as they say “out of the catalog “ in Jan 1967. The motor was removed by me when I started to take the car down for restoration. Before that it was never out of the car. The rest of the motor et al has the original orange paint.

My theory is until I can hear how flint worked is that the line worker was clearing his paint gun or picked up the wrong gun of Pontiac blue before he realized it should be orange. But I don't know if they built and painted other GM engines on the same line or not.

On other driveline parts, a daub of paint usually means something....but we usually have no way of learning what that is....

Neat discovery. I would just get on with life.

But... As far as I know, Pontiac had their own engine displacements and engine assembly lines. Engines were cast at Saginaw and assembled at Tonawanda.
