Thank you very much guys, i know its very simple for you guys to do this install, but this is my first time and so far so good, i really appriciate you guys walking me through this............ one more thing what is the little grommet deal at the end of the intake where a small hose from the brake booster called? I need a new one of those, can i get one from year one?
Do not tip the carburetor. Keep it upright when removing/installing. If you tip it upside down, you will most likely need to rebuild it. More .02
The PVC valve hose goes to the front of the carb. The brake booster hose goes to a barbed brass fitting on the back of the intake. If I remember correctly, the threads on the intake are 1/8", and the threads on the brass fitting from the original intake are 1/4". You will either need to find an adaptor, or get a threaded fitting with 1/8" threads.
PCV valve Grommet. TA Performance sells it, Part # 1240, 6.95 www.taperformance.com http://www.taperformance.com/products.asp?cat=140
You can get it at local stores too. It is a tight fit, so lubricate it and do it before you install the new manifold if you can. It is easy to push it through the intake into the valley pan if you try it on the engine. Ask me how I know?ou:
So this is where I need the chevy choke kit right? Is this my only option? Can I get it at a local parts store? Im still waiting for the intake bolt kit from YearOne
from the pic you posted, it looks like your talking about the throttle return spring bracket. you might be able to bolt your old one on and bend it a bit to work. o No: thats what i did with mine
I have 2 return springs one forward to a little pedestal that a intake bolt goes through it looks inexpensive it came on my car.The other hooks to the bolt that holds the throttle cable bracket down.These springs are smaller diameter than the one in your pic with along tail on them so you can adjust them to the right length and both springs cost around $5 together.

I intake installed and fired up the car, there is a very small knocking sound, if i turn it on and dont press the throttle it stays idling for a couple minutes, but if i start it and press the throttle i dies a second later, what is causing this? do i have to mess with the carb?
You won´t need a chevy choke kit!! Your carb has an E-choke, man. What the hell!! And why are you using a carb spacer? or is it a Q-Jet adapter plate you are using? But in my opinion it doesn´t matter. Both make no sense. You don´t need a adapter plate because the edelbrock carb bolts right on the manifold. And a carb spacer also makes no sense because I don´t think you´re building a high rev application with a dual plane intake and a 750 carb. I would remove whatever you have between the carb and the manifold.
Peter, If the intake manifold has a spread bore opening, you do need an adapter plate if you bolt on a square bore carburetor. The intake has bolt holes for both patterns, but there is the potential for a common type vacuum leak if no adapter is used. The adapter plate just seals the wider area at the rear of the spread bore opening. The simplest ones are very thin. I use this one http://www.jegs.com/i/Edelbrock/350/2732/10002/-1 I have an SP-1 intake with a spread bore opening. I occasionally use an AED 1000 HO carb(like a Holley 1000HP). I intentionally ordered the SP1 with the Q-jet opening because hood clearance gets tight with the taller intake. The above adapter is thin enough to not create a problem when using the big square bore carburetor. The traditional adapter plate is 3/4" thick and that would be a problem.
Can you post a few detailed shots of how you have your vacuum lines routed, and just a general view of the entire setup?
Sure, if you have a spread bore opening you need an adapter. I know. As you say, this manifold has bolt holes for spread and square bore carbs. But I dont hink that there is a common vacuum leak problem when you dont use an adapter. Worst case I could imagine is to apply a thin (realy thin) coat of RTV sealer to both sides of the of the gasket. But the adapter nelson is using flows realy bad. The primarys of the Q-jet are smaller than on the Edelbrock. So they wont flow what they could. Secondarys are smaller on the Edelbrock. So they flow not as much as the Q-Jet could. Lets see 750 Edelbr. instead of a 800 cfm Q-Jet. AND reduced flow on the primarys. In my opinion that should make max. 650 true cfm through that. In this case the performer makes no sense.
