is that a fuel line bracket or is that the bracket that should mount to front carb stud to hold the PCV hose?

[/ QUOTE ]Fuel line bracket. Supposedly the 69 Z's are to have one, but I never saw one on any original cars I have seen. The BB's had the bracket on the front stud to hold the PCV valve hose.

Jack Seymour reported.....

"The guy works with my brother and he was telling him he was a original owner of a 70 Camaro. My brother told him I was really into them and said he was sure I would love to see the car. Weeks went by and I was pushing just to see it, I was trying to get my brother to dig for details on the car. But the guy didn't even really know what he had, told us it was a SS 350 with the LT1 motor, I said WHAT, asked if it had stripes and split bumpers he said ya, so I new it had to be a 70 Z28 so now I'm pushing hard to see it,he also said he may be intrested in selling it because he was tired of it taking up room in the garage. I finally saw the car I was a little disappointed when I first saw the car, it had about a inch of dust on it vinyl top and no RS (darn) The more I looked the more I liked, to make a long story short, I bought the car after a little dealing.
Sense I've had it home it just seems to be a better find all the time. even though there are a few thing missing, including the TCS clip. I just couldn't pass it up knowing there just can't be to many original owner cars out there.
Thanks to everyone for the support and maybe I'll have it ready for Carlisle next year.

As Sam said,in 1969 the BB Chevelles had that same small metal bracket to hold the PCV Rubber hose in place,but no Fuel line bkt.was used.
In 1970 that BB PCV metal bracket was not used,but the Fuel line bkt. was.
Maybe this carried over into the LT-1 cars also?

That looks real good Chuck S.
I gotta admit,this car is winning me over too. https://www.yenko.net/ubbthreads/imag...mlins/cool.gif
As far as Jack mentioning it is missing a TCS clip,are we sure it even had one?
Speaking for the 1970 Chevelles,the early cars got a COMPLETE rubber TCS hose line connecting it to the Vacuum advance,TCS solenoid & carb.No metal clip was used,as it would have pinched the rubber hosing down.
But after a few months of production went by,beginning on January 13 1970,they redesigned that same rubber TCS hose to include metal lines in between those rubber beginings used on the complete TCS system from then on.
Thus they added the metal clip in the center area of the top of the passenger valve cover to hold the now metal tubed Distributor vacuum advance TCS line down.
Whats the build date of this Camaro?

Rick,

I assume you're referring to Holley carb equipped 375hp Chevelles, because my Qjet equipped 325 hp 69 Chevelle has no such bracket https://www.yenko.net/ubbthreads/imag...s/confused.gif

Thanks to everyone involved in photographing and posting the pics of these low mileage motors https://www.yenko.net/ubbthreads/imag...ns/worship.gif. I have had people questioning why the motor in my car looks so crappy (i.e., rusty and lack of paint) since the car has only 21K miles on it. These pics make it easy to see why. Everyone's memory wants to believe that the factory did show worthy paint jobs on these motors, but obviously that's not the case.

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
The Deuces got the same super tall studs, not sure why they are so long, but....

I used to think that the LT1's for the Z28 and the Deuces were identical, but I'm learning that there were some differences. At first I thought the temp sending unit was the only diff, but now maybe the dist shield and the fuel line bracket too? I didn't even know the shield and bracket existed.

The distributor shield should be in the Deuces since they used the same dist part #. How often do you see a LS6 dist with the shields? From what I hear, not often. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Could be that the shields weren't used all year, but I doubt that. Dist part # would have changed.

Marlin, see if Tommy K has a shield in his distributor on the Wallace car. Mine does not.

I bought one of those distributors for my Nova years ago from a Corvette guy. It was the right part # and date with that shield in it. It was the first I ever saw one of those. I was told it was Corvette only and was to help with the radio interferance.

On the rear engine lift hook...Is that where it should mount or should it be in the head?

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
Peter, Was the dist. you bought a aluminum hsg. type? The reason i ask is that corvette distributors are tach drive models from 63 to 74 and they are all cast iron hsgs. I have only seen 2 original LT1 Corvettes a 70 and a 71 and they both had TI ignitions ( I work for a Corvette shop), i dont think these shields will fit in the dist., with the TI pickup and pole piece. I have never seen the shield on Corvettes, not to say they did not use them on base cars.
My 69 Survivor Z28 ( owned since 72 ) came with a box of extra,s in the trunk, and in the box was the original dated smog pump,tubes etc, some small parts and also those point shields.
I was told that they did not use them until 70 on a post on TC, so they never went back in.
The 6,000 mile 70 CTB Engine is mine, it was out of a Rolled over 70 Z28, wrecked back in 70/71. I can assure everybody that it is DEFINATELY original and unmolested. It still has the original Delco Script Cap and Dated wires and Green Ring Plugs also.
Maybe the point shields were a Canadian Production deal only?
Weird?
I will check to see if the line bracket has part numbers and answer tonite when i get home from work.
Hope this Helps.
Mike.

The rear engine lift hook is in the correct place, but how about the different bolts used on it and the front lift hook?

Kurt, per the blueprints, all 1111437 (LS6) distributors were to be delivered with the shields installed. As a mechanic back in the late 70's and early 80's, I recall this being one of the VERY first things that got tossed the first time the distributor cap came off the car. I agree however, it is not often you still see any installed on cars today.

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
I owned a survivor 1970 Z (18K miles) and it did have the shields as well. The first thing I did was take them off and put them in the glove box.

......I wanted to further explain my statement about the rare TCS clip, that was previously mentioned. The following TOP picture shows Jack S's other 70 Z-28 which is restored & Citrus Green. The 2nd Gen Z-28 "experts" (at nastyz28.com) cant document the use of this clip at Norwood or L.A. Given the fact that almost eveyone removed the AIR "smog" from 70 Z-28's this clip is very rare to be found today. CENTER pic show closeup of clip.....BOTTOM pic shows another/different clip on right rear upper valve cover bolt that retains wires running to 432 TCS Solenoid/Switch......
I would like info/history as to why DUECE CTB engines didnt have TCS temp senders in Right head.....how was that function served otherwise.....regards, Chuck S

Ahhh..I see what you are talking about.Not the top Valve Cover clip I was referring to at all.
But that rare TCS clip looks very similar to the 1970 RPO CD-2 Fiber optic washer Jar Monitor clip used under the Dash to secure the fiber optic line.
I have one here,& can post a picture of it,if I can find it.

CamarosRus, Correct me if i am wrong but, in the picture you posted of Jack,s LT1, shouldn,t the spark plug heat shields have the half moon cutouts?
My 6,000 mile CTB engine has those half moon type, same as my 69 Z28.
Just wondering, not being critical.

SS427 12-09-2004 06:30 AM

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
That clip looks very similar to the ones used in many places on GM cars. One such place that comes to mind are the horn wire clips on a 70 Chevelle as well as the rear light harness clip used to attach the harness to the upper rear quarter area. I will have to pull on to confirm but I think they are the same.

CamarosRus 12-09-2004 07:15 AM

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
Regarding the half moon cutouts on shields.....I just looked at an ORIGINAL set of four and I totally agrree with you. I'm thinking that Jack's Green restored engine in picture is using repop shields. This will be another judging point to start using......
Regarding the "rare" TCS clip, there are MANY of us 70 Z-28 owners that hope someone can discover THIS clip easily available in another G.M. application. WE are also looking for the clips that go over rear edge of 70 L-78/LS-6 RARE Dual Snorkel Air Cleaner. These clips support the PVC hose from Left valve cover to right side of carb.....
The afore mentioned Jack S is the same person who repopped the 70+ Camaro transverse muffler and tailpipe hangars. These are NOW included with Gardners systems. Jack reports that finding a vendor to repop these misc spring clips is expensive and difficult. Anybody have an idea ???
Thanks, Chuck

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
Chuck,
I think it was you and I talking at SCR7 under the hood of my Deuce regarding the temp sending unit. The deuces have the two wire sending unit on the left head, not the right, but I believe it's the same unit. One wire for the warning light, the other for the TCS system.

This was probably the first difference we found between the Z28 vs. the Yenko applications for the CTB/CTC engines. We believe the reason is due to the wire harness of the different bodies, as the Nova SB V8 harness always has the temp wire on the left side fender well.

This 6k engine is excellent reference material! It has answered a lot of questions, and created new ones.

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
Marlin, The Z-28 and other Camaros with TCS have 1) Single wire sender in Left Head feeding gauge panel water temp gauge 2) Two wire sender in right head from TCS water temp sender to ???? ....... I really dont know the electrical schematic.....but are you suggesting that a DUECE left head sending unit operates the dash gauge and TCS function ??? if so why would not the Camaro have had same ?? Oh well, that's the way it was......so no matter.....regards, Chuck

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
I checked out my Wallace car and it does not have a shield in the distributor.

YENKO DEUCE REGISTRY 12-10-2004 06:05 AM

Re: Unmolested LT1 Motor with 6000 Miles / CTB Cod
 
Yes Chuck, the Deuces have the two wire sending unit in the left head that feeds the light and the TCS. If Yenko installed gauges into the Deuce, he would put the gauge temp sending unit in the right side head. I don't know if it was chance or if he realized the he shouldn't remove the original sending unit per the TCS situation. Either way, that's where it went.

Hello everyone!! I'm Jack Seymour These are my cars Chuck is refering to, This is a Great topic and having a unmolested 70Z I hope I have a few thing to contribute.
First you are right my Green car does have repo heat shields something I plan on working on!!
On the other hand my Orange car is all original and a blast just to look at and see just how things were done at the factory like it or not.
Not sure where to start but I think from the posts you know a lot about my car, As for the shielding in the distributor mine also has it, as for the head marking mine has the X's on the driverside head and O's on the passenger side. Mine also doesn't have the rear engine lift hook but the shouldered bolt is there so for some reason the factory must of removed it.
I could go on and on and on, I be watching and putting my two cents in also.

Jack,

Welcome! Please never restore it! Looking at your engine compartment will assist lots of folks in proper restoration of Norwood built 70 Z-28's.

Now for a little quiz... Anyone know why the 70'Z-28's always quickly got surface rust on the tops of the fan shroud cover?? Hint -- I had to figure out how to solve this problem after I restored mine to keep it show ready. https://www.yenko.net/ubbthreads/imag...lins/beers.gif
