46  Camaro Research Group Discussion / Originality / Re: Heater Hose Nipples on: September 24, 2013, 08:18:43 AM
Many thanks Darrell.

When I was at the Camaro Nationals in Frederick, MD this summer I saw a survivor L78 which appears to have the nipple on the water pump that was unpainted. I'm not at my home computer now but will post a picture of it tonight.

I'm also trying to unravel which type of nipple was used on both the intake manifold and water pump. Unfortunately the '68 AIM does not list the part numbers for a BB.  It would, however, appear from your picture and also the car that I saw at the Camaro Nationals, that the water pump nipple used a long hex type fitting and the intake manifold used a short type fitting. Not surprisingly all the Camaro vendors websites I visited have what appear to be the wrong type hex nipple for the big block water pump nipple. My car is an L35 but I would suspect that the L34, L35 and L78 all used the same type nipples but as you say, let's see what other say.

Thanks again,

Bob

Were the heater hose nipples (not the bypass nipples) on the intake manifold and water pump on a '68 BB installed and painted at the time the engine was built?

Thanks,

Bob
48  Camaro Research Group Discussion / Decoding/Numbers / '68 SS Emblem with Standard Grill on: September 22, 2013, 11:38:58 AM
So I'm at the point in my '68 SS BB restoration where I thought I'd tackle something easy; the grill assembly. I reach into my stockpile of NOS parts that I've been collecting for 30+ years and pull out the grill, parking lights, upper and lower moldings and SS emblem. BTW, this is on a standard grill not RS. I paint the grill, install the moldings and parking lights and now move onto the SS emblem. I notice that the SS emblem on my old grill has a different backing plate (see first picture) and the studs are very much different in size than the NOS backing plate I had in my stockpile (see second picture). Now I can't say for certain that my old SS emblem is original to the car and it could have been swapped out by a previous owner prior to me purchasing the car in '78. So with curiosity getting the better of me I start to look into the part number on my NOS emblem box. The part number on the box is 3981921 and the casting number on the emblem is 3982043. A quick Google search later reveals two threads which talks about emblems:

http://www.camaros.net/forums/showthread.php?t=120003
This threads states that the NOS emblem I have is for a '71-72 Camaro

http://www.yenko.net/ubbthreads/ubbthreads.php?ubb=showflat&Number=473348
This thread states that the NOS emblem is for a '70 Camaro but goes on to say that it is similar in design to the '68 emblem (p/n 3919194)

So now I turn to the '68 AIM and sure enough part number 3919194 is listed on page 294. When I look at the diagram in the AIM, I also notice that the backing plate looks to be much smaller than the backing plate that came with my NOS emblem. Now I know that the AIM is not always correct and this diagram could simply have been a copy from page 138 that shows the standard bowtie emblem.

Totally confused, I start to look at some of the Camaro vendors websites and I see that some vendors advertise the smaller backing plate (here is one from HBC - http://www.heartbeatcitycamaro.com/store/product/14927/Camaro-Grille-emblem-retainer-plate-1967-1968/) while others sell the emblem with the larger backing plate (here is one from Rick's - http://www.rickscamaros.com/camaro-grille-emblem-ss-for-cars-with-standard-non-rally-sport-grille-1968.html)

Soooo....I have a couple of questions...

1. Did part number 3981821 supersede the original emblem part number (3919194) shown in the AIM and would it be correct for my application ('68 SS BB not RS)?
2. If part number 3981821 DID NOT supersede the original emblem part number (3919194) then what year(s) is it used on?
3. Was the original emblem backing plate for a SS car without the RS option, the smaller type plate or the larger type backing plate?

It would be great if any of the members could look at their BB survivors to see what type of backing plate it has.

So much for a simple and easy part of the restoration!  Grin

Many thanks,

Bob

Does anyone know the correct finish of the fan heater motor (for a '68 BB)? Was this painted at the same time as the heater box cover and thus received the same gloss finish? The only thing I found was this post (http://www.camaros.org/forum/index.php?topic=4843.0) which unfortunately did not have any responses.

Thanks,

Bob

Thanks Bryon. Looks like the MS 201 15 seems to be correct. Both of my 1111169 distributors have this vacuum advance pod.  Though I'm not quite sure I understand the differences between the cams.
51  Camaro Research Group Discussion / Decoding/Numbers / Re: Vacuum Advance Pod Number on: August 11, 2013, 11:21:00 AM
Thanks Jeff. Then I wonder what application uses the 534 cam? I also have another 1111169 distributor with a 524 cam. I'm pretty sure the differences in the cams is the length of the advance slot but by how much I don't know.

Bob
52  Camaro Research Group Discussion / Decoding/Numbers / Re: Vacuum Advance Pod Number on: August 11, 2013, 09:54:34 AM
Many thanks to all but my OP was in regards to the correct cam for the 1111169 distributor not the 1111499 distributor.

Thanks,

Bob
53  Camaro Research Group Discussion / Decoding/Numbers / Re: Vacuum Advance Pod Number on: August 10, 2013, 05:51:13 AM
Thanks Kurt. I thought the 732 was used only with the L-78 and L-72 engines with the 1111499 distributor but I could be wrong.

Bob
54  Camaro Research Group Discussion / Decoding/Numbers / Vacuum Advance Pod Number on: August 07, 2013, 07:12:06 AM
I'm considering purchasing the correct date coded distributor (1111169) for my '68 L35 A/T project. The numbers on the vacuum advance pod are 201 15 and the number on the cam is CCW 534.

Are these correct for my application?

Thanks,

Bob

Sorry....it's an NOR car.

And just a couple more pictures...

Here are a few pictures of my '68 01D L35 air cleaner which I believe to be original to the car when I purchased it in 1978. Maybe I have the oddball lid, but mine has two silkscreen instructions!

Thanks Ed!

Mike - Good suggestion!
59  Camaro Research Group Discussion / Originality / Re: Big Block Distributor Hold Down Clamp on: July 18, 2013, 07:59:00 PM
Well, I didn't think I'd cause such an in depth discussion when I posted my original question! I figured surely someone must have run into this during their restoration, I'd get my answer and continue on with my project. Boy was I wrong!!

Anyway, I thought I would start to tabulate what we know so far from all of the previous posts:

Year    Engine    Build Date     Clamp Type

67         L30          610B               Wire
67         L35          704B               Stamped
67         L35          705B               Stamped

68         Z28          801B              Wire
68         L78          806?               Wire
68         Z28          807C              Stamped

Thanks Ed. Looks like mystery continues!
