Hi Donny,

  I know you asked for a '69 but I suspect '67 was the same. My 67 assembly manual shows the stick as a separate item so I assume it was added when the engine accessories were installed during the car assembly. What does the '69 manual show? On my original unrestored '67 L35 the dip stick body still retains the factory black finished, though it is faded and I can't tell what the gloss level was, but it is definitely black. I have the notes to my other 67 I restored in the mid-80's and I recorded it black as well. Hopefully someone here with a 69 BB will chime in.

No, it wasn't - the 396 dipstick tube was installed at the car assembly plant, not at the engine plant; it was natural (unpainted).

I have seen that stated before about being raw but I can assure you my original 396 stick body is definitely black. Unless 69 was different?

I was under the impression that 69's were unpainted. Please correct me if I am wrong.

I think there are many examples of not painted iin Gen 1 Camaro's along with other similar engines in other model cars. Does not mean whatsoever that what Mike has noted is incorrect on his LOS 67.

I guess it is very possible that 67's were painted black.  I will leave mine natural/unpainted.  Thanks again everyone.

1967 BLACK.

I would offer the following as proof;
Take a peek at the Color photo that is floating around of the line in 67 where they are loading the rear into a 67 camaro body. The car behind the camaro is a BB full size, you can make out the black painted dip stick tube w NAT handle?

Guess it depended on the plant - those are VERY early 67's, and in '67, St. Louis didn't paint the BB dipstick tube - maybe Van Nuys did (it was received unpainted from the supplier).

The "Painted Parts List" was issued monthly by the Chevrolet Central Office Paint Standards Department to each plant's Material and Paint Superintendents, listing every part that required paint processing at the assembly plant, and what process each part required. The Material guys got it so they could intercept the parts that needed painting, and the Paint guys got it so they could segregate the parts by the different paint processes they required. This was an internal document, not issued outside GM.

 Coverage depends on the artistic mood of the sprayer at the moment. Sort of like how the bell housing went anywhere from partial to full coverage.
One moment you can be like Bob Ross and another, Earl Scheib. Maybe it depends on how high the person was from the fumes?
  I attached a picture of my 67 4B LOS L35 showing the dip stick and you can see it is black.
Excuse the grease as the old gal is in need of a Cover Girl makeover.  Cheesy

Tonawanda painted big-blocks with exhaust manifolds bolted on. I have noted other pics with them showing lots of paint. In the early 70's that process was changed I believe JohnZ noted due to the workers complaints of paint burn off.

Photos below show the Tonawanda engine paint booth (at 300 engines per hour) and fresh racks of big-block engines; both illustrate complete paint coverage on the exhaust manifolds.

I don't recall exactly, but it was late 60's-early 70's; BB's and SB's painted on the same line.

Excellent information! Noticed the BB's were hung by manifold where the carb bolts on. Was that just for cast iron intakes or did they use that process for all Big Blocks? Is it safe or correct to assume SB's were completed the same way at Tonawanda? Was the same hanging process used at Flint?

WOW, I wonder if either of those painters lived to be 50?  I can't imagine painting 300 engines/hour without wearing suitable respiratory equipment!   Tongue

I can only assume (and hope) there was an updraft ventilation system pulling those fumes up and away from the workers otherwise Purple Haze sure had a real meaning from the buzzzz.
Certainly pre-OSHA days!

I painted anywhere from 3 to 6 cars a week without any kind of respirator and I'm here to tell you I wish I had spent that money and bought one. That's not including the countless hours I worked in the shop with the Bondo dust and primer flying everywhere. I'm paying for it now.

The side opposite the painters station is all ventillation.  Could have been later 60s - looks like a short leg water pump though. Great discussion - brings back memories.

Appears to be a water curtain in front of them. Smiley
Was hoping John or someone in the know could answer my earlier question concerning how the big blocks are shown being painted, i.e. hanging by the intakes carb bolt holes. Earlier question- Noticed the BB's were hung by manifold where the carb bolts on. Was that just for cast iron intakes or did they use that process for all Big Blocks?

If you take another look at the photo, the second engine is a SB - they were all (SB & BB) hung the same way at Tonawanda, and the same way at Flint (starting in 1965 at Flint).

It must be because it was never restored. I examined it closely and it still has many areas left covered with what looks like semi-gloss black paint.

If you ever take the long case bolts out let me know what you find. The end plate on my starter is natural, I did rebuild it but can not remember taking any black paint of the cover, or for that matter, why I would.
Is the cast mounting section also painted black? Huh

Hi Bob,

   The car is on a lift so it's easy to lower the starter and look at the nose finish. The end plate looks easy enough to remove so I can do that.
With the end bolts removed what are you looking for specifically?

A consensus has been reached that the starter was completely painted as an assembly. That means that special attention would have to be taken with the cast end housings so that proper grounding would be achieved between the starter and the block for auto and bell housing for stick. As for the bolts, just looking for paint build up. Just do not remember the  end plate and casting being painted.

Bob,

 I removed the starter motor and gave it a wiping of gunk. Good thing I took it down because the top of the solenoid was cracked and a large piece missing.
I looked at the motor and noted the following.
* The long end screws (bolts) had traces of paint on the heads and under the heads were clear so it was painted assembled.
* The nose shows no obvious signs of a 'clean area'. The picture does show the paint edge at the nose and the other shows traces of black paint all over.
* The two motor mounting bolts however show that when it was tightened it dug into the metal.
* The paint looks to be a gloss black or a shiny semi gloss.

Here is my thinking of grounding for the starter motor....the rear support that is held with a nut as shown in UPC L35/A5 may be the intended method of grounding the motor body to the block through the long main case bolt with the threaded stud on the end.

Per John Pirkle Jr, "All of the information Dad and I have collected(archives,pictures,and interviews with engineers and line workers from the early 50s through the early 80s) shows that the starter was painted as an assembled unit,so the rivets,pole shoe screws,etc.would also be painted.The solenoid was masked in some instances,so you saw both painted and plated units."

Do your stamped numbers on your main case show paint in them ( stamped then painted)?
Is the phenolic end that is broken black or brown?

Bob,

 After carefully cleaning out the stamped letters I can clearly see black paint inside the stamped area.
There is even paint on the pin and C clip that holds the shift fork so the whole unit looks to have been painted as an assembly.
The solenoid is black with Delco in the middle. The case itself looks to be zinc.

Mike,
Did you notice if the starter mounting pad on the block has paint on it.The starter being painted black as an assembly still causes me to wonder about a good ground return. All ground wires on the Camaro have star or lock washers to achieve a good ground through painted surfaces. Looking at L35 A5 no such precaution was taken on any of the starter fasteners.
With the block being painted and the starter brace being painted, bolt #4 would not be a very good ground return even if #4 nut cut through the paint on the bracket.

Hi Bob,

  The engine block area the starter nose contacts had several spots of paint on it. I examined the two block bolt areas carefully and though I can see paint traces around where the outside of the bolt would sit, the areas that came in contact with the metal are slightly scarred from digging and there is no paint on it that I can see and nothing on the bolt heads either that came in contact with the starter. That makes me wonder if the bolt holes were plugged when painted (and solenoid covered), sort of like when the engine had caps on things like water pump necks when being painted. That's the only thing that makes sense. I wonder of John Pirkle Jr. would know.
