My New '68 Camaro Z/28 Butternut Yellow

Did you remove the tin splash pan on the bottom of the intake - the date is cast in the area under it that can't be seen unless the pan has been removed - and as far as I have seen they all have it cast there!

I forgot about that. I for some reason thought it was in another location. Maybe I'll pull the little pins and check it out. Thanx... D

Danny, the date code is probably hiding under the oil splash shield on the bottom of the intake.

Make sure when you drive the pins back they go in tight. You don,t want one to fall out.

If you have the intake off anyway - its not such a bad idea to remove the pan off from the bottom side just to clean all of the crap that might have accumulated up under it anyway - regardless of whether you are looking for a cast date or not.
And as Kelly stated you want to make sure the knurled pins aren't at al loose, so by hammering the metal around the original holes a bit smaller in addition to staking them in place with some good quality Loctite or Permatex product it should assure that they won't come loose..

Well got it all apart. Pulled the pan under intake. Tapped a wide screwdriver in on each corner and just turned it sideways and they popped up. Pan was pretty clean, and so was the underside of intake. Took pictures and reinstalled pa. Cleaned holes with carb cleaner, blew them with air. Filled holes with Permatex Ultra Black. Then put a small amount under each head and knocked them in gently until they bottomed out. I feel confident they are in for good. Found some numbers...

4. 18. 68 = April 18th 1968. Which should be ok for this car as EVERYTHING is May.

4 583 Don't know what that is, Part Number?

Then also a row of numbers and some proof marks? 10 / 20 / 30 / 40 / 45 / 50 / 60 / 70

Reassembly Prep... Got every surface wiped down one more time with Lacquer thinner. Applied small beads of Permatex around water holes, set gaskets, applied a bead around water jackets on top of gaskets. Ran 3/8ths high bead at the front and back. And a small mound at all 4 corners. Applied some to each bolt threads and installed. Started by running all of them in until they touches. Then pulled my alignment pins. Word of advice, do not make them out of stainless. Would have been nice to get them with the telescopic magnet. Wrong stainless, non magnetic. Started in the center and worked my way out at 15 #'s, then 20, then 25. Bouncing back and forth, middle to back, then middle to front. Until all were at about 27 #'s.... Danny
