1972 Base 350 cid intake manifold
I'm working on a survivor 1972 Corvette, all matching number.
it has the orange 350 CID engine, base 200hp.
it has the OEM intake manifold, the OEM air cleaner with the bottom heavy damaged which need replacement.
but it has a too big carburetor, is the Edelbrock 1407 2354 , 750cfm
So I have two options right now...
buy a new OEM carburettor and bottom air cleaner,
or
buy a better intake manifold (Edelbrock) with matching carburettor and a good air cleaner that fits
what you can suggest?
I read tens of post but I'm really confused.
I would like better low RPM torque and power
thank you so much!!!

summit shows a lot of options availabel,
but their sales consultant says MAYBE none willl fit...
thank you for your support!

Not Edelbrock anything, keep your orginal manifold, yes you take a small loss on performance.
find an orgianl carb, and have it properly rebuild.
If it needs rebuilding (how does it operate now?), you can ask Lars for some advice on proper jetting and best rods to match your engine's needs, or get some advice from others here on the Forum.
Your present best option is to keep that carb. It may have been produced by Edelbrock, but they bought all the original tooling from Rochester and built them for years. There should be no issue with reusing it.





The 1407 is the Edelbrock re-pop of the Carter AFB - not the Q-Jet. So he really needs to dump the Edelbrock and find a rebuildable Q-Jet for the car.
The original Q-Jet was 750 cfm, and it will run exceptionally well once correctly set up. There are a lot of good (and bad) ones for sale: I'm having customers picking up very nice rebuildable original carbs for under $75 off eBay and CraigsList.

I also have a 1972 survivor. I did a few stupid things twenty five years ago like painted the intake and a few other small parts, but other than that it is all original with the exception of a few parts.
One of them being the carburetor. I could not find a correct carburetor for my 454,4-speed car. So, when I happen to run across a carburetor for a 1972, Corvette with a 350 and an automatic, I snapped it up.
They look exactly the same from the outside, but there are a few minor differences on the inside. Bla Bla Bla.
Well, not too long ago I ran across a 1972, 454 , automatic carburetor. That is a lot closer than the small block carb I have.
So, now I have a 1972 , 350, automatic carburetor that I have no use for. It is all built and ready to go. I thought you might have an interest in it.
Let me know what you think.








+1. Keep the OEM manifold too.
