the lash would be better set at .026"/.026" with stock stamped rockers.  You will be off the clearance ramps (more clatter and wear) if you use the .030"/.030" setting.

If the gear is not flush with the crank land, it is not on far enough. Be sure the beveled side of the gear bore is facing the inside of the engine.

I've never examined the back side of the crank gear (if I ever did it was so long ago I can't recall it).   The little 'timing dot' has to be the outside in order to align the crank and cam gears, so the bevel must be on the inside if one does that...

True. I had trouble once with pulley alignment on a build and had to tear it back apart to look at everything.  That crank radius/gear bevel observation came after a lot of head scratching.  If someone else is having issues, something is probably installed wrong.

Picked up a number of tower clamps myself at the boneyard.  I always look for vans and commercial vehicles.  Not too hard to find if you keep your eyes open. 

Some smog check valves are common across the other lines.  Luxury GM cars frequently still have original smog stuff and some of that works for Chevy too.

Probably just a pre-production marketing photo.  They added and changed stuff all the time that was different from production.  Michael Lamm's book has a number of similar pix.  They get a lot crazier than that.

Send it to Lars Grimsrud.  He is THE Q-jet man.

Hi Joe,

That's where I put it figured if it was wrong I'd change it. Doesn't seem to do much, but a GM design engineer put there, so who am I to argue.

I guess I can hi-jack my own thread. I put the roof rail weatherstripping in today, seem to fit snug. I debated using adhesive, but didn't. Would you recommend using adhesive?  Thanks Paul

Use some 3M black weatherstrip adhesive.  They do not stay in place over time unless you glue them in my experience.

Intake manifold port gasket leak is very common on fresh builds.

1969 - Orphans / Re: 124379N640398 entire Z drivetrain on eBay 69, no 68

I wonder why the seller believes it's a '68? or maybe a typo when he entered the ad??   

"68 VIN with '69 Suffix.... Transmission VIN derivative stamp does not match...  Seems like it might just be a bunch of parts.

I just bought a fuel injection car spacer.  They look the same as the heat riser valve but do not have a flapper/shaft hole/weight. Just a straight thru design.  No cutting or mods required.

Do you have the heater box off yet?  It has been some time but I seem to remember that helped. 

Reuse the old dum dum or get some 3M strip caulk before you try to wrestle it in place.

The block assembly date/suffix stamp surface has been altered to appear that it has broach marks.  Looks to me like a fresh stamping from the photo.  Just go find an old engine that is not collectable to see what they are supposed to look like.  Nobody ever re stamps a non-collectable engine.

The Engine and Transmission VIN derivative stamps were both done at the same time with the same tool as the 2 pieces were being prepared for installation on the factory assembly line.  If the two stamps do not match each other, it is unlikely they were stamped together in the usual way.  Add to that the missing digits, and it looks even more likely that one or both are not original. 

Folks around here are shy about giving too many details away but these are pretty obvious.

Not necessarily...

This VIN derivative block stamp does not look to be normative practice.  If it is "possible" that it could happen some other way, then please enlighten me.

That block date suffix stamp is obviously not original.

Looks like the one Camaro Specialties owned and restored, it was listed on their website.
Edit: Discussed a while back at TC:

Thats what I was guessing.  I do not have anything to add on the car.

The VIN derivative stamp on the side of the block has to be identical to the transmission VIN derivative stamp as they were both done at the same time with the same tool setup.
