Plugs weren't used in the exhaust manifolds on non-A.I.R. engines - they used the same 527 and 826 castings, but they weren't drilled or tapped for the air manifolds. The only engines that used factory-installed plugs in the exhaust manifold openings were those that specified RPO KD1 (Less Air Injection) for overseas export.
But since all 527 and 826 castings went on manual trans cars, all were drilled and tapped. Never seen either of those manifolds not drilled and tapped.
Lots of BB manifolds have tapped and untapped versions.

So for all 69 SB, auto tans applications, there are no A.I.R. connections and the casting numbers are:

LH side:  3942529
RH side:  3932376

correct?

Rich........Could I bother you to remove the air cleaner and take a couple sideview pics of the carb for reference. Also, a picture of the air cleaner, which was missing. The air cleaners are easy for me to get at the local boneyards here in AZ for $10-15 off passenger cars. I'm sure the air cleaners are dated like my buick's, so a picture would be all I need
Any help appreciated

The small bore air cleaner for the small 2 Bbl carb (SAE 1-1/4 throttle plate; used on 1969 Camaro 327/210 Hp and 307/200 Hp engines) is a harder find than the aic cleaners for the larger 2 Bbl's (SAE 1-1/2" throttle plates) that were used on passenger cars, 327 / 235 Hp engine for example.  Matter of fact, it was one of the hardest pieces for me to find. 

Air horn on the SAE 1-1/4 carb is smaller and hence the mounting hole in the bottom of the air cleaner is smaller.  I have an air cleaner from a '70 Nova hanging on the garange wall that looks like this one except the mounting hole in the bottom is too big to fit the air horn of the SAE 1-1/4; 2 Bbl carb.  It was made to fit the SAE 1-1/2; 2 Bbl Carb which was primarily used on full size cars, i.e. 327 / 235 Hp engines in 1969.

Underside of the air cleaner also has a scalloped area to fit around the 90 degree fitting on the fuel line inlet to the carb.  Air cleaner without this scalloped area will not clear the fitting properly.  The air cleaners for the larger 2 Bbl won't have this because the fuel line comes in to the front of the larger 2 Bbl carb as opposed to up from the bottom and into the side via the 90 deg fitting for the SAE 1-1/4 carb.

The mounting hole diameter in the bottom half of the air cleaner is nominal 2-1/2".  Note that '69 2Bbl air cleaner mounts with the snorkel turned toward the RH side with the locating tab fitting into the mating slot on the carb air horn.

Wow, that carb looks great. Whats the correct color for the carb called? Is this like an eastwood carb restore kit?
Thanks for pointing out the 2 versions of mounting hole, you saved me the grief I may have incurred

Is the heat stove the same on the passenger cars, or camaro specific?

Rich, take your time with pics, it doesn't have to be tonight, when its convenient is fine

Front view of the carb.

I had the carb restored by Daytona Parts Company  http://www.daytonaparts.com/


I don't think (not sure) that the heat stoves are the same on passenger cars.  Most passenger cars seem to use the "rams horn" exh manifold which would probably use a different heat stove and tube arrangement.  That one needs more research - just a best guess on my part.

They did a fabulous job, and there pricing seems fair. I spent a little less than double that, to have my 70 GS Stage 1 carb restored. IMO is money well spent. Heck the stage 1 carbs are selling on ebay for ridiculous money, in the $2500 range.
Nothing looks better than a correctly restored carb

I now know the carb isn't missing anything, thanks to your pictures.
I'll see what I can find this coming week, Im going to do my quarterly west coast junkyard spree
I really appreciate your help Rich, and if you are looking for anything, just let me know. Its not uncommon for me to bring home 15+ posi units, lots of sheetmetal-(anything but 67-9 camaro, there's rarely any of that in the yards anymore), but chevelle stuff is still around, sport mirrors, altenators, carbs, heads, maplight mirrors, t-3's, 200 4r, T-350, T-400, 700r4's, steel cranks, tilts, radio's, steering wheels, trim, etc.

I do them all, buicks, olds, pontiac, chevy, mopars, sometimes ford-usually for the 9" posi chunks, and 67-72 chevy/gmc  trucks

Thanks for the offer - there is one item -

If you ever find the correct throttle rod for this 2Bbl, I could sure use it.  I don't have the correct one and if you look in the pic above, you'll see that in order to make what I have work, I've got it connected at the wrong location on the carb.

That is the piece.  Problem I've had is finding the right one with the right offset so that you can go from idle to WOT and be able to adjust the TV kickdown on the tranny properly.  If I put the rod I have in the proper location on the carb and adjust the TV kickdown properly, the throttle will not open far enough to get WOT.  I'm sure I don't have the correct linkage rod - need to find that beast in order to solve this little dilema. 

With the linkage that I have, installed in the lower hole as shown on the above pic, I can get WOT and properly set the TV kickdown.  Hasn't been a big deal, but i'd like to get it set up correctly.

Thanks in advance for looking.

Richard
