And a question I'm wondering if someone can figure out the answer...
Alternator brackets.
Engine #1, flat steel bracket
Engine #2, stamped steel bracket
Engine #3, flat steel bracket
Engine #4, stamped steel bracket
Body style change, which makes the exhaust manifold change, they use a different upper bracket? #1 and #3 appear to be B body according to the lower alternator bracket, #2 appears to be Chevelle. (Which really makes no sense because even though the lower bracket is different on B body vs. A body, the upper bracket could remain the same couldn't it?)
#1 has A/C, #2 and #3 don't, can't tell about #4 but that shouldn't matter anyway.
The first 3 appear to be California emission with the smog pumps, but that shouldn't matter and they don't all have the same bracket anyway.
No power steering on #3 but that shouldn't matter anyway.

On exhaust manifolds, I have know that in this era they were often painted with engine paint since forever, if you never had or saw a new car it would be one of those things that might elude your eye since the paint burns off fairly quickly and I have had many cars where remnants of engine colour are visible near the flange and the heads, both Pontiac and Chevrolet engines. Often the entire manifold wasn't painted but oversprayed during production process. Many sales brochures show the engines with painted manifolds too.

THAT IS WHAT YOU CALL ORIGINAL, TRY RESTORING YOUR CAR NOW AND PAINTING THE MANIFOLDS,
CARB BASE, COIL BOTTOM DIST ETC. ORANGE OVERSPRAY AND SEE THE REACTION AND COMENTS
YOU GET AT CAR SHOW.

Yes, lots of the experts overspray at the top but you never see a restored car with an entire glossy orange manifold! Everyone is doing it wrong!

Here we go, a Pontiac brochure with painted exhaust manifolds...
But the pulleys are the wrong colour in the brochure. Talk about inconsistent!

You can get ceramic coating in any colour now. I think I'm going to do it on my next motor.
Cruise night, hood open. Heh, check out this idiots orange manifolds. What was that you said? Pulls out the brochure, points 4 times at the image...SEE, SEE... originally came this way!!!

This 66 Brochure is gettig closer to what we see on the line photo...
On this topic, does anyone have an original exhaust manifold with any paint left on it near the outlet? I've seen a number of them over the years that have paint on areas near the cylinder head but there never seems to be any left on them down by the outlet. Does it burn off more there because it's hotter there maybe?

There are smog pumps on some of the motors. I would say these are 1968's based on the oil fill tube and fill cap style
Here are 1959 shots from Life mag, same manifolds
note all the TURBOGLIDE flywheels! those turboglides were popular in 58 59!

Look at all those glossy manifolds... man, that must have stunk when they started the car for the first time!

You're right, they have to be. 67 still had the breather in the filler cap, 68 was in the valve cover.

Notice the rad hoses on the front and rear engine are the same ,but the middle one is diff? Also looks like canister oil filters...in 68?

gee, you are right. now i am leaning toward 1967 truck, but the oil fill cap tells me 68, but wait.........its got smog emissions, so maybe that is a correct closed pcv system. Im changing my response to 1967. the alternator brackets are 67, and no accessory bolts in heads, so 67 it is!
4SPEED427 said

Good point, canister filter can't be 68 can it? Some guys even claim the spin on filter showed up at the very very end of 1967 production but on any cars I've ever seen/parted out the can was on a 67 and older, spin on was 68 or newer. But have you ever seen a non vented oil cap on a 67?

I bet these pictures are from California. California had much stricter emissions rules in the late sixties. I remember a 67 Chevy van with a six and it had an AIR pump and a sealed oil cap on it. It was imported from California.

In 1978 I was in California and pulled into a service station to get a tire patched. There was a 66 Malibu 283 in the shop with the hood up and and when I walked over to it I saw a smog pump on it. That was a surprise!
Beaumontguru has a 64 Chevelle 283 wagon that I first saw in about 1979-1980, shortly after it had been brought here from California. When I looked under the hood of it the first thing I noticed was the breather system on it, very different vs. a Canadian Chevelle of that era.
The more I think about it the more I think those have to be 67 engines, California emmisons as you stated. Beaumontguru will be able to tell us but I bet the oil filler tube and cap is different, set up for a closed system where the crankcase fumes are vented back into the air cleaner to be burned.
beaumontguru said

Yes Calif would be closed oil cap. 62 to 65 had earlier cap. Look up a 65 l79 to see the early closed system. California used the closed system with or without smog pump.
4SPEED427 said
Nov 20, 2020
Dave, it's hard to see this oil cap on these engines. Do you think it's that cap with 4 ears on it?
beaumontguru said
Nov 20, 2020
No the 67 68 only has 2 ears. Early ones have 4.
4SPEED427 said

Ah, ok. I can picture that one now that you mention it. Flat top with a very prominent rivet head on top, which you can sort of see in the picture.

Interesting details. I've never seen a painted orange exhaust manifold; now I know why.

I had always thought they were left in natural state, to rust naturally.
I saw this shot on another site, what a great shot showing some of the details on assembly line engines.
Check the exhaust manifolds on the 2nd and 4th engines---bright orange!
Alternator brackets.
Engine #1, flat steel bracket
Engine #2, stamped steel bracket
Engine #3, flat steel bracket
Engine #4, stamped steel bracket
