Default Intake Manifold

Can someone tell me what I need? I just bought Corvette valve covers to replace my valve covers with breathers, so I'm looking for an intake with an oil fill tube, whether it be cast iron or aluminum (aluminum preferred).

But the other requirements are:

1. Must accept Quadrajet carb.
2. Must fit '69 cast iron heads
3. Must be low enough to clear C1 hood

I've researched the Internet and I don't think they make such an animal!

My engine is a sbc 350.

If you find the stock intake for a low HP Vette it might work. It wont be aluminum and I'm not sure if you can bolt your carb onto it.

Wouldn't the Edelbrock 2101 work? It has a boss for fill tube, just needs to be machined.

Yes, looked at that before. Is it difficult or expensive to find someone to machine for fill tube?

You should be able to use a cast iron manifold for a '66 -'67 Chev 327/275 hp (not Corvette). I use to run a L79 aluminum intake on my '60 but a Quadrajet will not fit that intake.

As Skids suggests, a 2101 may work. I just need to get that boss machined. Also I'm not sure of the height.

I think edelbrock makes a version of the 2101 already having an oil fill tube hole. Don't know the number but should be on website, just for your situation.

Edelbrock 2703 has the hole for fill tube, and includes fill tube.

A is 3.74", B is 4.80". Carb pad height is 4.27"

But does it take a Quadrajet carb?

JEG'S carries it (2703), but alas it does not take a Quadrajet...

However the 2101 does accept the Quadrajet...

(Summit has it.)

Good luck... GUSTO

You can do that yourself with the proper size hole saw. I did. Worked fine and never gave me any trouble. Just had an assistant (my wife) hold the manifold steady on the floor while I drilled, after carefully marking the center of the boss.

Do you remember the type & diameter of the saw and where you got the tube?

i'm not sure that i would try it unless i had no other option; one slip or a dull cutter and it will get ugly very quickly...

and, unless you already have the correct arbor/hole saw, it could be as expensive as having a competent machine shop do it.

The cast iron 66-68 intake for a 327 (NON-Corvette, 68 for Vettes) is just the ticket.
They all had the hole up front for an oil fill tube and they had a Q-jet bolt pattern. And yes, it is a 100%, direct bolt-on fit for 85-earlier first Gen SB heads.
This particular style iron intake is as common as dirt at swap meets for super dirt cheap prices. I'm talking $5-25. For a stock style 4bl intake, it is not only my favorite, but it is as good as it gets. The casting numbers for these intakes are 3872783, 3875954, 3905393, 3919803. The first 3 have a threaded hole for the temp sender to the left and just below the thermostat housing, the 4th (1968) manifold has the boss cast shut because in 68 the temp sender moved to the cylinder head.
SOME 69 intakes of this style still had the boss for an oil fill tube which could be machined. But later manifolds DID NOT have the boss, thus it is NOT practical to attempt to machine a hole on later manifolds without the boss.

Also, there was a cast iron manifold with the hole for an oil fill tube which had a bolt pattern for an AFB. These manifolds were used on 62-65 300hp/327 engines (commonly referred to as a "300" manifold). They are also an excellent intake, but they are becoming rather scarce (not expensive, just scarce).

I ABSOLUTELY agree 100%!
Spend a little time and locate a 66-68 cast iron Q-jet intake.

I have a cast iron 3875954 but shipping costs would be a pretty high from Canada. .

Good info, DZAUTO, but I was hoping to find aluminum to trim some weight also. My current intake is 3927184 and has the boss if i remember correctly (car's in shop), so I may be better off by just having it machined. No one has yet mentioned the cost to machine this.

it would be almost impossible to guesstimate how much, but it shouldn't be much... let your fingers do the walking through the yellow pages or do a google search for nearby machine shops; explain what you are doing and if they can do it, then drive over and talk...

Unfortunately, there is no FACTORY stock style LOW PROFILE alum intake with a Q-jet pattern. The closest you're going to get to that in a FACTORY alum intake is the 62-63 versions with an AFB bolt pattern or the 64-later alum intakes which all have a Holley bolt pattern. If you wanted to use any of those, it will require an adapter plate plate to permit installing a Q-jet which, for sure, will interfere with the hood.

This is a Z28/LT1 intake on my Chevelle with an adapter plate and a Q-jet.
This arrangement will permit using a Q-jet, but will make it much too high for an early Vette

I don't remember the size, but I used a Chevy fill tube, so just measure that and buy the appropriate size metal-cutting hole saw. After you have marked the center of the hole, drill a pilot hole for the hole saw arbor. Just don't get in a rush, and be sure to use an assistant or secure the manifold so it won't move on you.
