69Z Holley carb studs

[L78 steve]

Does anyone know if the correct 69Z carb. studs are reproduced?

Steve, There are TWO different types that different people call original.

First, there is the type that most vendors sell, which are the type that look like the end of a regular stud or bolt and has a dimple drilled or machined into the end.  I bought several sets of this type from Jerry M.  Corvette vendor's also have these.

Second, My intake and Gary's (69z28-RS) intake from his HO Z has the type with the undercut machined at the end of the threads.  I have seen several other examples of survivor type cars, and they had this type also.  Please check out the tread of Chick's friend's Hugger Orange survivor Z, this car has this type of carb. stud also.  (Look for the engine photo's in Chick's thread.)  I think this type stud is very hard to find, and are THE original carb stud, especially for a Z28.

I need to clearify. I need the studs for the carb base.

Steve, exactly, those studs I was referring to are for carb mounting to intake.  Please check out the Hugger Orange survivor.  If enough restorers start requesting these, they will start making them.

Paul, thanks for pulling that photo over, wish I could do that.

Steve, Good luck finding a set of these studs.  I nearly bought a 472 intake last year JUST to get another set of these studs.  I'm kicking myself for not buying it.  Steve, without luck involved, I seriously think you would have to find an intake with the studs intact to be able to acquire any.  You might see one set for every 30 to 50 or more 472 intakes.  I've been looking.

Here is a picture of my 06A Z28 carb stud and fuel line support bracket, Interesting that mine is Black compared to the silver cad of other survivor. Owned this car since 74 brkt has never been touched.

Picture of almost NOS 69 Z28 Intake, been sitting since 70, it was bought over the GM parts counter in 69. The carb studs are black and small unthreaded portion appears longer.

Picture of 6,000 mile 70 Z28 carb studs, they appear the same as mine and posted survivor.

As usual, thought provoking topics on CRG -

I had to go dig out the Z intake, off the engine and stored since '80, car was bought in '73 - thank goodness I never changed them, They actually have remnants of dichromate where the carb base protected them - all four.

Regards,
Steve

I'm happy to see such a strong response regarding this correct carb stud.  I count six different 69's listed here, either by photo or mention, and another set on James blue 69Z survivor just posted.  My point, these speed shop / Mr. Gasket type studs with the dimple, as sold by most vendors as correct, are not correct.  I saw many 69 Camaro's at the Nationals with this dimple stud score above 990 points.  Hmmmm!
