QUADRAJET MANIFOLD (preferrably aluminum):

1) Do you know if GM (or anyone else for that matter) still make/sell the quadrajet manifold (preferrably in aluminum) for the SBC?

i know gm still sells it for the big-blok, but this does me no good.


2) If no, then do you know of any good sources for used or remanufactured or copies? Again, i would prefer aluminum, but at this point will take an iron.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

Edelbrock sells a Performer RPM Q-Jet and a standard Perfomer for the Q-Jet and they both are aluminum.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

If you're talking about the stock Chevrolet aluminum intake-I don't know if they're still being made but you can pick them up in the yards or swap meets for 20-30 bucks. I have one I'll be using on the stock 350 in my Silverado in place of the cast iron one. Why? Because I can !

Re: QUADRAJET MANIFOLD (preferrably aluminum):

1) the problem with the edlebrock units is (and it's a shame that edlebrock quit making the quadrajet copy?) is that it is not exactly stock compaired to the chevy manifold---i.e., no 4 holes and no provisions for ported tvs switches---and i can't hook up my stock stuff to it.

2) not so much as getting tired of aftermarket, it's just that aftermarket is not exactly a bolt in unit for me for the reasons listed above. In other words, for example, a dart aftermarket block basically is an exact bolt in----because it is. ARP fasteners are an exact bolt in. The edlebrock manifolds are not. Essentially, i need an exact copy; It does not nessesarily have to be made by GM, but it must be an exact copy.

3) exactly---superstock people rule. We can learn alot from them. (too bad they are not telling)

4) i may have to try the salvage yard. i know for sure gmpp was selling the aluminum version up to recently. Everything that i like from GM has been discontinued. Just another thing to consider in the current state of gm.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

i've got the factory aluminum intake from the 305 in my 86 Caprice laying out in the shed at my mom's place-that intake was used on pretty much every 305 and 350 powered car and truck GM made in the 80's until the switch to TBI, so finding one shouldn't be that hard. but finding one that isn't warped might be kinda tricky. i know this is the intake that all the claimer class roundy round guys liked to use a while back.
otherwise you could always get the ZZ4 intake which should have all the provisions you need- i think it is the very same part as the Edelbrock Performer egr intake (2104?) but with a different logo cast in and the automatic 75% GM markup on the price.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

Re: QUADRAJET MANIFOLD (preferrably aluminum):

1) yes, like that one; i may have to resort to ebay.

2) That was going to be my next question; If i manage to find one, whether it be aluminum or iron, how can you verify that it is not warped?

3) upon further looking at it, that edlebrock performer /zz4 could probably work as i only have one tvs switch that taps into the manifold near the heater hose and thermostat housing and then, of course, the vac modulator line near the rear. All the other hoses branch off the two tvs switches or from the carb.
But the thing is, they don't have the 4 holes. And, this, to me, is psychologically unfulfilling.

4) The part number, i believe for the original gm aluminum is 14007377. It's no longer listed in the gmpp catalog. And, according to Gilbert Chevrolet, it's discontinued.
The iron's part number is, i think 1409011. i'm not sure of it's fate, probably discontinued as well. Perhaps someone still has these parts on their shelf despite it being discontinued.

i think list price on the aluminum was like $1000 or something, so maybe it's good that i could never get one? Actually, do you suppose that's why it's no longer available----because no-one would spend that kind of money for much cheaper or used manifolds? Another brilliant move by GM.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

what exactly are you trying to do? what kind of car are we talking about here?
most manifolds out there either have enough holes to do what you want, or you can easily drill and tap a hole into the coolant crossover to mount the vacuum switch.
or there is the other option for if emissions testing isn't a concern- just forget about the emissions stuff and hook up the bare essentials -heater hoses to the coolant jacket and vacuum advance, power brakes, pcv, and trans modulator lines to the runners for vacuum.

you don't plan sincerity.
you have to make it up on the spot.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

It's an 83 C-10 and the thing is that, after further examination, i think the edlebrock ones will work but i just feel that it won't run exactly the same as before. Plus, i'm the type that likes things stock (for now); i actually don't like bolt on aftermarket top-end stuff----i.e., manifolds carbs etc because of a)previous bad experiences with them and b) i just like things stock anyways---the 70's/80's GM was such a cool period (for me at least) and c) i don't know enough about these kinds of things to be switching parts just yet.

What i'm attempting to do, while initially seeming perverse, is to create an exact running test-stand engine of what i have in the truck so as to create an educational, running model. This is down to every last vacuum hose etc. i find that i can learn easier this way. i already have a 305 sitting dormant in my garage that is on a runnable test stand. The only major difference is i have the 2 barrel intake with a 2GC. So, while the idea seems bizzarre, it works for me.

Re: QUADRAJET MANIFOLD (preferrably aluminum):

Nova said what I'm thinking!

Buy an old ebay 2101 and plumb it the way you want and go! Unless you need the EGR deal, then ebay one that has it on the casting.

Paint the SOB Chevy Orange and 90 percent of the kids won't know it's not stock!

Re: QUADRAJET MANIFOLD (preferrably aluminum):

Run a wanted ad in your local craigslist for a stock aluminum intake from the 80s. They are hanging on the walls of every Chevy gearheads garage collecting dust... They can also be found in just about any salvage yard. Don't pay more than $30-$40

Re: QUADRAJET MANIFOLD (preferrably aluminum):

i went to shopintakes.com, which apparently is summitt, and no luck there either. This is yet another thing that pisses me off about GM---they still sell it for the big-blok---part#14097092. How many people do you know running a bigblok actually use a quadrajet carb? i would be willing to bet none? There are at least 20 small blocks for every bigblok out there, therefore the likely hood of someone running a quadrajet on a smallblock is much, much greater.

So, it looks like i'm "stuck" with used; How can you determine wether the intake is warped?
