Originality / Re: Original long bolts for 1969 L/78 motor mounts

« on: February 22, 2009, 06:30:33 PM »

Just a follow-up to my original post on this topic.  I was surprised by the number of views, but
no responses.  I did get a few PM's though.  Many thanks for those.  Maybe the correct original
setup is more rare than I thought.  In any event, I have been eagerly looking into this on my
own and I've purchased several original correct items ( I believe ) over the past two weeks. 

Shortly, I will post more images to show all of the original components in the original big block
motor mount setup.  These will include frame mounts, motor mounts, stop bracket, standard
long bolt & washer for passenger side and odd-ball longer bolt, lock washer, flat washer, bushing,
flat washer setup for the drivers side.  I'll have some questions for the group once I post everything.

Through all of this I was able to finally make sense of the AIM page on this topic as well.

Originality / Original long bolts for 1969 L/78 motor mounts

« on: February 14, 2009, 04:49:56 AM »

Big block Camaro's had a unique motor mount that used a threaded receiver on one side.  This meant that a nut was not required to secure the long bolt.



I have an original pair of these rare motor mounts and I will be hunting the correct original bolts that were used in conjunction with these mounts.  Can anyone
post information on these bolts?  I need to know correct head markings, overall length, bolt head style, etc........  An image or two would be fantastic.

Can anyone shed any light?

Bad feedback isn't going to get you a working antenna.  Contact ebay and tell them you were lied to.  Demand your money back!

John,

Any chance you can snap a picture of one on your Z and post it for me?

I am assuming your setup is all original........

John,

The AIM calls them out as hex head screws.  Hence my confusion......

Would it be correct to assume that "speciality transmissions" like the M22 and CX coded THM400 would
more likely to have been pre-built and waiting for call to assembly?  Any owners of such originally equipped
cars have build date vs. transmission assembly date information?

Guys!

Can anyone post an image of an original screw ( how many were there anyway - 6 or 8 ? )
that was used to attach the flapper valve frame to the ZL/2 hood?  I am looking at a complete
assembly right now and the screws are the only items I've personally never seen........

General Discussion / Re: Fake '68 Z28 Convertible article in Hemming's Muscle Machines

Perhaps they should change the name of this magazine to: Hemming's Fake Muscle Car, or Hemming's Cloned Muscle Car.

I personally don't like it - at all.  I also saw an article on a Challenger that was "cloned" to a 440 6-pack in another issue of this
same magazine.  What's going on here?  Are these cars going to be legitimized now because they have correctly dated and
numbered components?  Where do we go from here?

Kurt,

Sounds like a good candidate for a Research Topic ( decklids, rear spoliers, spoiler fasteners, etc... ).

Originality / Re: GM BBC Oil pan did it ever come with.....

« on: July 29, 2008, 08:34:33 AM »

Goin' further on the oil pan subject: did GM at one time or another ever extend pan capacity by cutting the sump and re-welding it back together whist adding material, thereby gaining more pan volume..  I guess they did not have the space to go the "kickout" route and starters at this point in time were of the large Delco variety..  Does anyone have a picture of the welding done by GM on an original BBC GM pan??? Why were the oil drain bolts changed from the side of the pan to the rear of the pan or vice versa, from back to side???                Ted

Nope - GM never did any cut-and-weld modifications for added capacity on any production oil pans. Have no idea why the location of the drain plug moved around.

John,

I saw a MarkIV windage tray on ebay earlier this year that was more rounded than the traditional flat version.  If memory serves me, that went for much
bigger bucks than normal for a BBC windage tray.  Wish I saved that auction........

If it is what I think it is, that is a Corvette SHP oil pan.  It should also be a 5 quart pan.

.... The builder fully discloses that it's a counterfeit convertible; in fact, he built it to highlight the fact that fakes are out there and are getting harder to tell.   ....

I'm not bashing the owner, but the the hell's the point of building a counterfeit car like this only to prove that fakes are harder to spot?
Don't we already know this from the 569 ZL-1 tribute cars fro sale on ebay......

Decoding/Numbers / Re: Julian date code on THM400's in 1969 model year.

« on: June 23, 2008, 10:20:13 PM »

I'm guessing here - Maybe it's the 2160th CX configured TH400 built for 69?

I was wondering about that myself.  But with a late January '69 date, could Chevrolet possibly
have built and installed 2159 CX's before mine?  Were there even that many?

« on: June 10, 2008, 03:01:09 AM »

According to the CRG link provided ( THANKS ED! ), I guess it is a Julian date code.  However, it rolls over into the next year.
So this transmission was assembled on the 29th of January 1969.  That makes sense because it came from a early March '69 L/78.

Now, the 2160 is a sequence number according to the same link.  What exactly is a sequence number?  Was it the 2,160th THM400
built that model year, or the 2,160th Turbo-Hydramatic built?  Anyone know exactly what the sequence number represents?
