Engine hook bolts on manifold

[sbmiano]

I am new to this sight and am fresh off the Camaro Nationals legends show.  It was a blast and a great experience.  Had the car judged (stressful at that level) and in return got a nice list of things to be done.  One in particular was odd to me. Judges said the bolts for the engine hooks were incorrect.  They are installed under the same bolts that hold the manifold on.  Im confused, did they have 2 different bolts for the engine hooks and then the rest were manifold bolts?  Thanks for your input and more to come. lol

lol my bad its a 69 z with a build date of 04D and was built in Van Nuys plant

Yes, the bolts for the engine hooks were shouldered. The rest were not. If that is the worst thing they found, you did pretty well! Welcome to the site. It's a great place for info. Great car people here.

thanks do you have a picture of them ?  are they the same finish as the others only shouldered?  Thanks so much

I was also in MD at the Camaro Nats, and greatly enjoyed it, meeting great people and seeing some fantastic cars.   What year? and which one was yours??

Not the clearest picture, but this gives you an idea what the shouldered bolt looks like.  Jerry MacNeish rebuilt/restored the engine.

Hans did you paint the intake and thermostat housing?

Were the shoulder bolts used on big blocks also?

Here is a clear pic of ours off our 68Z. This is one of the three originals. Our 68 had one each used for the engine lift hooks and one used for alternator support.

Interesting details, dimpled (manifold) carb studs (?) and partially painted head on intake manifold plane.

No, that's natural aluminum for both.  Jerry restored both using his aluminum restoration process.  He also did the valve covers and distributor.    The above picture was taken the day I received it back (late January this year).

Edgemontvillage was referring to the engine orange on the head surface between the valve cover and intake manifold... ie. the upper part of the machined surface for intake gasket...  which normally would not get painted on such an engine (with aluminum manifold and aluminum valve covers)..

I really don't know.  I'd be curious to get Jerry MacNeish's input - he restored the engine back to factory spec.

Very interesting. I thought that the lift brackets were unpainted ok aluminum intake cars. Perhaps I was wrong. I just stripped the paint off of mine.

For the small population of original cars I've looked at it seems many 69's and later (70 LT1's) had natural lift hooks. There was a real debate about this on the Yenko site sometime back. On our 68 I have them painted but here is a late Sept. 69 built Z/28 survivor with no paint.
