Set the engine in my '57 today. The engine was partially disassembled when I got it so there are a few things I didn't remove that are now "puzzle pieces". Can some one tell me where this special bolt goes? What attaches to it? The intake and timing cover were already off so I think it may go somewhere in that area. I took everything else apart. Thanks in advance.

 

It looks like an intake manifold bolt . But it was used in a location where a power steering , generator , or A/C bracket could fasten to it .

 

I believe it is a manifold bolt, but I think its location is near the drivers side back of the carburetor for bolting the ignition wire loom assembly to the block

 

There are more than one of those bolts on the intake. One goes on the front passenger side to hold the clamp for the heater hose.
