i would like to put the cast version of the z-28 intake on my 68 el camino. the alternator bracket mounts on the left side. the top of the bracket bolts to the intake. will it work on this intake?

Should if it is a '67/'68 intake b/c a '68 Elky still has the alt. on the drivers side b/c of the short w/p..

UNLESS I am missing something????

OR do you mean a cast-iron version of the old Z- intake??? Then, I don't know????

pdq67

Its a GM performance part #14096011

Here is a pic of it in case you need it.

If you don't already own it, it sure looks expensive for a cast iron piece @ $182.

Used to be $300 I think.

All you have to do is look for the lug for the mount to bolt to. On any intake.
Lots of aftermarket intakes have the lug undrilled.

Don't remember if an RPM has it or not.
You could grind the Edelbrock off and paint it.
It's not noticeable at first glance.
Also, I thing the 69-72 pickup brackets fit a short pump but on the right side like a long pump.

That manifold does not have the place on it for the upper bracket. It would be on a vertical surface in front of the left-hand water passage, below the thermostat.

69-up all use a long water pump with the alt on the pass side.

What year Z/28 are we talking about? I didn't know there was an iron version. The '67-'69 302 manifold was not a spread bore either. Here's how the '69 alt bracket fits...

Here's how the '69 alt bracket fits...The iron manifold is over the counter only, it was never installed on any vehicle at the factory. It's mainly used for certain classes of oval track racing where a cast iron intake is required. I've got one, but I doubt I will ever use it, it must weigh 75 pounds.

Geargia69 are you saying that it won't work and does not have a lug that can be drilled out. I just like GM stuff. My dad wofks @ a GM dealership and I get a discount on parts. I'm open for suggestions or could this be adapted to my application?

That is correct. It won't work, and it doesn't have the place that the bolt hole could be drilled into if the place was there.

Print the pic of the GM part and carry it out to your car, and compare them. I think it won't be hard to figure out what's missing.

The bracket system from 69 up until sometime in the mid 70s was like DjD's pic. After that, they shortened the little arm of the top alt bracket that goes over to the water outlet bolt in the pic, and instead made it go to the boss on the top front of the manifold in front of the water outlet, like the GM part pic. So, the GM manifold, is clearly made to work with the late-model steup; and NOT with the 60s stuff.

looks like i better choose another intake. thanks for the help

If you want a GM intake, look in the GM Performance Parts catalog at the aluminum ZZ4 intake. It may have the mounting boss you are looking for, and it's a better manifold.

The ZZ4 manifold has it. And it is in fact a better piece, performance-wise, than the old one.

The ZZ4 (10185063) can be bought at www.gmpartsdirect.com (http://www.gmpartsdirect.com) for $190.67 Shipped.
www.sallee-chevrolet.com (http://www.sallee-chevrolet.com) has it for $185+shipping

Description:
SBC Aluminum ZZ4 Intake. This manifold is used on all ZZ series 350 HO engines and also can be used on all small-block Chevrolet’s thru 1986. This aluminum manifold produces the same horsepower as the previous high-rise design, but provides increased hood clearance and more versatility. It has a dual-pattern flange that can accommodate both standard-flange Holley and spread-bore Quadrajet four-barrel carburetors. This manifold has provisions for all late-model accessory brackets, EGR (exhaust gas recirculation), and an integral hot air choke. A heat shield can be mounted underneath the manifold to prevent coking when EGR is used.
Technical Notes: This manifold carburetor flange is approximately 1/2” lower than the LT1 manifold

How does the Edelbrock RPM for a Small block compare? It's only $152 from Summit.

It would be possible to use the iron Z-28 manifold on a 68-earlier setup simply by using an earlier alt adjusting brace. Many of the 67-earlier SB engines used an upper alt adjusting brace which attached to a stud/bolt at the upper, left water pump location. This arrangement would easily allow the use of the iron manifold. The thing that I really don't like about the iron Z-28 manifold is that it has ZERO provision for an oil filler tube at the front. If you examine the Edelbrock manifold closely, you will notice that it has almost EVERYTHING necessary for use on an early or late engine setup. It even has a boss for installing an oil filler tube. Any good machine shop should be able to open up a hole for installing an oil fill tube. Especially if they were provided an early manifold with the hole to use as a template.
I will never understand why Chev felt it was necessary to eliminate the front oil fill tube!!!

If you will look closely at Dennis' (DjD) manifold, it is a 69-later style Z-28 version. There is a welch (freeze) plug in the hole where an oil filler tube goes. The factory 69-70 alum Z-28 manifolds had this plug installed in the hole, and then the 71-72 Z-28 mainfolds were cast with only the boss for an oil filler tube and no hole.

It was emissons laws Tom, not totally Chevrolet's doing.

i'm looking @ the RPM but that ZZ4 intake looks good as well. wouild both of these work well with an xe268, double hump 461 heads w/2.02 valves and a Q-jet?? it looks like the ZZ4 is not set up for an oil fill tube or does it just need to be machined?

Either one will work well, but the RPM manifolds are not drilled for both carbs. You will have to specify the RPM-QJet.

Leo,
Olds kept the oil filler tube at the front of the block for many years, it seem as though Chevy could have also.
