Default So, here's our motor......

It's greasy and dirty but how bad does it look and what, if anything, are we missing? I know the carburetor isn't on there yet (that goes on tomorrow) but what else might be missing? The A.I.R? We haven't driven it yet but we have heard the engine and it sounds great. I know the plan was to get it repainted but we're going to wait on that now, too much going on with the new building......one stress at a time please! So, after everything is done tomorrow we might send it out to be steam cleaned (the motor and everything underneath) and then it's off to the detail shop and we'll enjoy it 'as-is' for a couple of months.

I don't know if those are the stock exhaust manifolds but they don't look like they had A.I.R.

Yep. Looks like the manifolds were swapped when the AIR was removed.

Thanks my 76 ray and Easy Mike, I'll start a list of things we need to swap out.

So, does that mean my car used to be owned by a gearhead who wanted a little more HP?

I am restoring my S/B 69. I find it very interesting that the fuel filter and lines look correct but there is no clamp holding it steady which would have connected to the AIR. The exhaust manifolds are not correct. A non A/C has a 5 blade fan that looks right, but the shroud does not appear to be metal, might just be the picture. Also the radiator does not run to an expansion tank, not sure what that black thing is where the tank would go. Valve covers indicate a 350/350 I guess. From what I have learned on mine so far is that in 69 there were 3 versions of stuff for that model year. Early mid and late. I guess GM was doing some weird stuff back then.

Do you have a picture of where that clamp should be and what it should look like?

When the manifolds were mentioned earlier today we called the man we bought the car from and he said they were like that when he bought it so the original owner must have switched them. I'll be on the look out for the correct manifolds and A.I.R. system.

Yup, some 69 L46 cars had a copper radiator and no expansion tank. Depends on when it was built. As you mentioned, 69 had many running changes.

Default air

I will see if I can get a pic. The AIR has a threaded hole right abve the fuel filter wear you would put this round clamp the size of the fuel line , so its not real big.
No AIR but you can see expansion and shroud. This may help?

You have brackets for ignition shields, but no ignition shields! Everyone likes chrome... until they have to change their spark plugs.

Control arm dust shields would help keep it a bit cleaner too.

Here is where the fuel filter bracket attaches to the A.I.R. pump bracket.

I am ashamed to share this picture, but it is the "before" picture. Alot of poor condition/incorrect items.

Back in the day my first new car was a 1968 Camaro and one of the first things I did was to remove the air pump....only I inserted brass plugs into the exhaust manifolds...seems strange to have swapped them out. Anyway if I remember correctly it wasn't to increase hp so much as it was to help the car run cooler.

We have had a complete tune-up done on the engine (along with some other things) so those shields may be there but not in place just yet. We'll talk to our mechanic in the morning and I'll ask about those things. Thanks

Thank you for the picture.....and hey, don't worry about the before shot, we all had to start somewhere and I certainly put mine out there dirt and all!

Looks like an after-market siren or horn.

No, because removing the AIR gained him about 1 hp. It means the previous owner had no real clue about how the AIR functioned but sucked up the media hype about removing it.

So the advantage of keeping the AIR is. . . . . ? My understanding is that the AIR system was strictly to continue the combustion process in the exhaust manifold for emissions reduction. Kind of a bandaid fix by the engineers pending unleaded gas and catalytic converters.
