Hi All,

I recently completed a rebuild of the top end of my engine.  Car overheated and I cracked a cylinder head. Found a used head, had all the machine work done to both heads, blasted it all and painted everything in Bill Hirsch dark blue paint.  The process took several months for me, but when I took it all apart I labeled every hose, wire, etc.  My question is, I can't seem to figure out why there is a threaded hole in the drivers side cylinder head towards the front end of the car, see below pictures.  Can anybody tell me what goes there?  I have an original 67 service manual but couldn't find any mention of this hole.

I also included a few random pics of the engine, what good is a thread unless it has lots of pictures...

Thanks for the help!

Here's a pic of my '66.  Looks like a sender.  Water temp?  Your sender may be on the other head in the rear, in which case you just plug this one.

By the way, it's looking great.  I see you use the same blue tape for marking hoses and wires.

Thank you to all that responded online and via PM.  It only makes sense that it is the water/coolant temp location.  This is what makes a site like this so good, helpful friendly info.

Mose - The blue painters tape is the best, I can write with a sharpie on it and it doesn't leave any residue when removed.  When I did the tear down of everything I used a bunch of that blue tape and zip lock bags to keep track of the various bolts.  As they say, bag and tag everything.  Pictures also help...   Smiley

Hey Mose, was that paper clip throttle linkage a mid production change-over?

Haha!  I was waiting for somebody to notice that.  Thanks Otto.

It was like that when I got the car.  Don't know what it's supposed to look like.  I kinda like it.  Goes well with the tomato juice can used for a vacuum canister.

Hey Mose,

Nothing special about the spring, just a spring with the last coil having a 180 degree bend in it.  Crappy cell phone pics for reference.

I always thought those Vacuum Cannisters looked like Juice containers.   Must be cheat to make, using old cans from the Company Canteen.

In the picture from Cad67Deville ----
At the coil bracket, disconnect and turn the last coil of that throttle return spring about 180 degrees counter-clockwise and insert the spring end UP through the hole and you have the "correct" factory installation for that spring as per the Shop Manual.

Where did you get the Air Cleaner?  I've been looking for something to replace my stock one.

Geoff - Thanks I didn't know that.

Sloggie - I got the air cleaner from Bitchin Products in AZ.  http://www.bitchinproductsinc.com/  It is cast aluminum and had that dull gray cast look.  I took it to a metal finishing company and had them polish it to what they called their mirror finish. Not quite like chrome, but shiny enough for me.

I think the spring on mine may be a little small as well.  No need for a lead foot.

You should see the vacuum canisters in the 70s F100 pickups. They are identical to coffee cans. Same number and location of ribs, same diameter. The only problem trying to use one for restoration purposes is getting the coffee out without using a can opener.

Hi All,

As mentioned previously I did a cylinder head job on the car.  The problem is I can't get her to start now.  Checked the battery (had it charged) pulled the starter (had it tested - tested ok), even rotated the distributor a little trying to advance the timing to help it start.  No luck!  The car makes a loud clicking sound when I turn the key. It turned over a couple of times, but can't get her to fire up.  Any ideas???  I tried attaching a video of me holding my cell phone recording the sound but it was too large.

ANY IDEAS ARE APPRECIATED!

Thanks,
Trevor
