Exact engine painting method, 1967 L79

[Mike E.]

I'm playing with a 30k mile 67 L79 convertible. It was parked in 1974, and the original motor is seized from sitting. The motor has never been apart, (the intake has been removed and put on a different engine) and still has the intake gasket with GM on the tab, etc. Steel head gaskets, etc. This engine was a major oil leaker. I'm slowly and carefully trying to remove all the crust without losing any original markings.
What exactly was the sequence of painting, and what was masked, what had boots on it, etc? I'm finding areas of very little orange paint, and areas of orange paint drips. No paint on areas of the timing chain cover behind the water pump, etc.Also finding evidence of silver mist overspray on the heads.
help me understand sequence, method, etc. I realize the way it was intended vs. how the line workers actually did it was not one and the same, and this was prior to robotic painting.
Thanks for whatever help you can share!

Mike,

Here's a thread I started a while back on BB engine painting, but it contains some good info by John Hinckley on how Flint painted the SB.

Mike,

Here's another BB thread that has some SB info as well:

Mike, This is great! I'd love to see it after cleaning. That had some major grungy goo on it when I saw it. Please take photos as you progress, and I want a CD !!!!!

You want me to post a few of the "before" pics, or do you want to hold off for now.

This is gonna be a GREAT THREAD!

Re: Exact engine painting method, 1967 L79

Thanks, Joe, for those two links. I'd still like to find greater specificity regarding the L79, although many of the BB principles come into play.

Mike,

You're welcome! I hesitated to post those, but you had zero replies after a day or so. I figured something was better than nothing and it would at least bump you to the top of the heap. I hope you get the L79 info you really need!

Re: Exact engine painting method, 1967 L79

Mike probably not much help, but.....

Here a re a few from a '63 300HP 67k miles before I cleaned it. I found yellow paint under much of the orange. Primer maybe? The heads were changed though so not sure if it's all original orange.

These from a low mileage convertible. Unknown history of paint. (yes.... wrong MC cover)

Mike,

Under "similar threads" at the bottom of the page is one about 66 aluminum intake manifolds, which will be the same.
You may want to search under engine painting, or intake paint. There are a lot of older threads with photos on how others have done this and what the factory did on day 1.

I read that no primer was used so the yellow on he engine from our '63 will remain a mystery.

Re: Exact engine painting method, 1967 L79

Thanks guys! I'll continue to search older posts. Is it fair to assume this sequence:
1) engine orange with masks on
2) masks removed
3). Flat aluminum along edges of intake.
Were valve covers installed before aluminum touch-up, or was there a mask of some sort over valve cover area of the heads?

Re: Exact engine painting method, 1967 L79

Mike,
Have read all previous responses to your thread and unless I missed somewhere I am surprised no one has mentioned anything about all the grease pencil marks that were made to the bare cast assembly before it was actually painted. If you are looking for accuracy I think they are important since the paint application was brisk and coverage varied. The grease pencil markings more often then not showed through the paint in some areas because of the light paint application. Have the specific procedure and colors for the grease pencil marks as well as the paint application for 56-57 Flint blocks. It is rather lengthy and I am not sure it was the same 10 years later.

Re: Exact engine painting method, 1967 L79

Dave,
Its always good to hear from you. I've been progressing ever so carefully, trying to make sure I don't obliterate anything original. I looked for the possible HT on the front of the heads, and nothing. I will be using simple green on the block sides soon. The motor was an oil-leaker, so in some areas it protected markings, but in other areas the oil residue is baked on. I'm photographing everything. Slow and steady wins the race?
I would love to compare what I've found on this and my bow tie 62's with the 56-57 info you have to see how things progressed over the years.

Mike,

Maybe you have it all figured out by now, but I stumbled across an article by John Hinckley today. Here it is:

Scroll to the bottom for the paint info.
