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.
