Hi Greg,
As Terry mentioned the 71 AIM will be a BIG help to you. The AIM is the Assembly Instruction Manual that was used on the factory production line. It's a few hundred pages of drawings that will make you get all weak kneed when you see it.
Another big help for you would be to get the GM Chassis Service Manual for your car.
The NCRS store sells both of these 'must have items' for you as your working on your car.
Regards,
Alan

PS: Left hand or right hand, just curious?

Gday Jack, Terry & Alan

My Corvette is Left Hand Drive and there is no way i would mutilate her by changing the steering to Right Hand Drive. Our Government recently made one right decision by passing a law that any Left Hand Drive Vehicle over 30 yrs old didn't have to change the steering to Right Hand Drive, YE HA.....

I have gone through the Corvette Assembly Manual and looked at the diagrams relevant to my needs, if you have a look at the pic on page L365 you will see the Fuel Block hides the Junction of the Vacuum Pipes. This is the area i need to understand.

Is there a Plastic "T" joiner behind the Fuel Block or a Black Plastic Joiner i have that looks like a Straight Piece of Plastic with a hole either end, with TWO other Pieces of Black Plastic moulded to that at Right Angle's, about 1/2 inch apart with a hole in one end???????

I have also gone through the following books with no luck. They show some relevant diagrams, but not every thing i need to put the whole picture together.

(1) 1971 CHASSIS OVERHAUL MANUAL, passenger car & 10-30 series trucks.

(2) 1971 CHASSIS SERVICE MANUAL, chevrolet - chevelle - monte carlo - nova - carmaro - corvette.

(3) CORVETTE Authentic Restoration Guide 1968 - 1982. By Richard Prince.

(4) CHILTON'S CORVETTE STINGRAY repair & tune-up guide 1963 - 76. 2nd edition 327 - 350 - 396 - 247 & 454.

(5) CHILTONS CORVETTE 1963 - 1983 All U.S. & Canadian 305 - 327 - 350 - 396 - 247 - 454 models, including fuel injection.

(6) CHILTONS "GENERAL MOTORS" CORVETTE 1963 - 82 repair manual.

(7) HAYNES "CHEVROLET CORVETTE" Repair Manual 1968 thru 1982 All V8 Models.

(8) ILLUSTRATED CORVETTE BUYER'S GUIDE. By Michael Antonick ( i was getting desperate )

(9) CORVETTE 1968 -1982 RESTORATION GUIDE. By Richard Prince ( the Corvette on the front is the same as mine, accept my has Black Interior ).

(10) HOW TO REBUILD CORVETTE ROLLING CHASSIS 1963 - 1982. By George McNicholl.( i was gettting MORE desperate ).

(11) HOW TO RESTORE & MODIFY YOUR "CORVETTE" 1968-82. By Richard Newton.

(12) As well as the AIM...

I did some home work before i posted my question on the NCRS Technical Discussion Board, but i have no luck with the books above, GOOGLE Search etc etc.

Dose any one have an LS6 they could send me some pictures of the information i need or any other ideas of where i might find some more clearer diagrams???? My e-mail address is harley13@bigpond.com

I apologise to every one for being a pain in the ring gear, but i want to get the Vacuum Lines Right!!!!!!!! I could patch them up so they work, but that's not how i want to restore my beloved Corvette, i intend to have her NCRS Judged.

All the best to every one, i hope to hear from you soon!!!!

Kindest Regards...

Hey Greg -- that is an impressive library you have there.

It is work time here on this side of the globe, so I don't have access to my library, but I'll do some checking tonight when I get home. I'll also check my photo collection and see if I have something that helps.

Did Jack’s photos help?

There is a 4-way connector in the vacuum line for Holley AND AIR (Air Injection Reactor) equipped Corvettes -- and it sounds like that is what you are describing.

More later.

Greg,

The book you need to buy is M. F. Dobbins 1968 to 1972 Stingray Fact Book. It will answer your questions. By the way, unless you have an original 1971 LS6 Corvette, no one is manufacturing the correct steel vacumm line. It is unique.

Re: TROUBLE IN OZ, HELP!!!! 1971 LS6 Holley Solenoid Vacumm Line Routing

Greg,
The vacuum lines are more clearly shown in the LT1 section of the 1971 AIM, sheets A9 and A10. Corvettes equipped with Holley AND AIR had the same vacuum routing BB & SB for each model year.

The only photo I have of an LS6 Passenger side intake doesn't show the 4-way vacuum fitting. It is exactly the same picture that is drawn in the LS6 section of the AIM.

As others mentioned Dobbins 1968-1972 Vette Vues Fact Book has several LS6 photos that are mostly correct.

Hi Terry

Thank you for your help!!!!

What are the page numbers in the AIM you are referring too L --- & L --- . I find the AIM difficult to navigate.

I have ordered the 1968-72 Vette Vues Fact Book, by Dobbins. It will take just under two weeks to get here.

All the best matie!!!!

Hi Warren

I have ordered the the book you recommended, thank you for the heads up about the book.

It is not an original vacuum pipe, i purchased it off Corvette Central.

My Corvette is a genuine LS5 with some of the origianl paper work, POP Card, Window Sheet, Warranty Book and Tank Sticker.

After much searching i have dicovered that the original owner had the LS5 Engine up-dated to LS6 specs. I can't tell you what's on the inside, but the engine has the 4803 List Holley because my Vette is a 4-Sp, Alloy 3963569 Intake & the Alloy Rectangle Port Heads. I suppose it could be said it's not an original LS5, but i don't have the funds to change the internal & external parts back to LS5.

My Corvette has 38, 140 miles on the odometer and the last rego sticker on the windshield is 1983. The wear and tear on the machanicals indicate to me that the miles on the odometer are correct.

Thank you very much for your help Warren!!!!

From a grateful OZi!!!!!

Re: TROUBLE IN OZ, HELP!!!! 1971 LS6 Holley Solenoid Vacumm Line Routing

Gday Terry

I have collected as much information, dvd's and books as i can to do the best restoration of my Corvette as i can, but it's so hard finding the correct information this side of the pond.

I have wasted much time and money by listening to people with differant information about the same question over here. After finding out there was a chapter of the NCRS over here i joined straight away and after talking to the members i have found i'm going to have to undo some of the work i have already done...

I hope you find some pic's you can send to help me!!!!

I'm having trouble opening the pic's Jack sent me, but he has send me another message telling how to open the e-mail with the pi'c in it.

You have already helped me Terry with just a few words, i have not put the AIR back on yet, so that explains the unused port on the four way connector.

I'm going to have to leave you now Terry, it's 8.30 at night over here and the American TV Show "OVERHAULIN" is about to start and i like to watch it.

I hope to hear from you soon matie.

Kind Regards...

Greg...
