I am looking for the best performance intake manifold for my 1976 with EGR port. Base Small Block 350 with Holly Carburator existing. The manifold needs to be CA SMOG legal. Is the Edelbrock Performer Series CA legal?

Thanks

Yep!

That's what I am running on my 80 L82.

I contacted Edelbrock and it is true. They do not have any intake manifolds with the required CARB approved numbers and don't plan on certifying them. Looks like I'll need to go back to the original intake manifold and get it on Ebay. Bummer.

The Edelbrock #3701 intake manifold which is 50 state legal is still available from Summit or Jegs.

ChromeVette

Thanks Joe - I see that on Jegs it says that the manifold is 50 state legal. When I called Edelbrock they said 2 years ago these were classified as direct replacement parts, but now CA needs the EO# CARB approved versions. Edelbrock will not be doing any testing on these models any time soon so I guess the question is if anyone has successfully - recently passed CA smog with these on them? How can they make someone take off the manifold that was previously 50 state legal???? CRAZZZZY

Joe Papa

Direct replacement parts do not require an EO number which is what I believe was written in my instruction sheet. I will have to dig it up and see if it is so. I am due for a smog check very soon as well.

I have not been hassled about my intake manifold ever. I've run both the 3701 and the ZZ4 intake - 10185063.

EGR SYSTEMS: Edelbrock EGR-equipped Performer manifolds are intended as a direct functionally identical replacement for their O.E.M.
counterparts. All exhaust emissions or emissions related stock components are intended to be retained and functional. Non-EGR equipped
manifolds will not accept stock EGR (Exhaust Gas Recirculation) equipment. EGR systems are used on some 1972 and later model vehicles
and only in some states. Check local laws for requirements. Manifolds not equpped with EGR are not legal for use on any emissions controlled
vehicle where such equipment is required. This was taken from their instruction manual.

This intake manifold is also available from Jegs; 50 state legal direct replacement.

If you decide to go spreadbore I have a nice alum GM egr manifold for sale. $125 shipped.

Thanks Joe,

This is great information. I think that going with the direct replacement shouldn't be a problem now, Good news! Now I just posted another thread entitled: What is EGR High Performance? Corvette America sells 3 options for 76':
1. EGR with special high performance
2. EGR w/o high performance with Cal emissions
3. EGR w/o high performance

All of the product images appear identical. What is the correct EGR for my application that requires SMOG and uses the AIR system for L48? Does the High Perf get better mileage?

Thanks again

ChromeVette

I would love to install the spreadbor, but I/ve read that the direct replacement manifolds also require the CARB certified carburetor. What carb is legal/works with this setup where I won't have any issues passing?

Thanks

ChromeVette

What carburetor have you used. Best performances and legal?

Thanks

A 76 q-jet the first number is 1 and the 6th is 5. The 5 denotes Calif legal.

I'm running a QuadraJet from a 78 L-82 carburetor that I've re-worked with custom air bleeds and some other tuning tweaks (enlarged idle fuel circuits, notched secondary air flaps, enlarged accel pump discharge holes and POE restrictions).

Shark Racer,
That's about the sexiest block I've seen and with those AFRs how'd you get that to be legal? Are you really in San Jose? What have the smog techs said about your setup? I also don't see the AIR system in your engine bay. Maybe your year didn't require it. If you have the L82 I thought they all came with AIR

Shark Racer

AFRs are legal (EO #D-250-2). I'm actually in Santa Clara, I haven't lived in SJ for a few years and have bounced around the south bay a bit but haven't cleaned up the location since it's "close enough" and not everyone knows the nuances of the area.

It's an L-82 carburetor, but my car is originally an L-48. A forum member gave me this carburetor a number of years ago when I was having issues with the carburetor I had. I had it rebuilt by Ace Fuel Systems in the early 2000s and did it again myself ~2 years ago. You're right on L-82s coming with A.I.R..

If you're referring to my engine build thread, the AIR tubes were not installed until after I'd broken the motor in. They get in the way of tuning, but were installed for my smog check. The only thing the smog techs asked about was the headers, which have an EO sticker (which I posted near the emissions label).

And it came with a cast EO number right on the manifold. Worked just fine.
