changing intake and carb : issues
Have an '80 with stock 350. I decided to change the intake and carb, as I have never learned to leave well enough alone. 
Anyway, with an Edelbrock performer and a holley 600, have run into tons of plumbing problems. Water neck blocks one coolant sensor plug hole, and the carb blocks a vaccuum hole. Plus I worry the carb, once installed won't clear the hood.
Open to suggestions. I wanted to mildly tweak this up as it is a real dog to drive. We have emissions testing here (visual is a big part) so that factors in seriously. Is there ways to replumb , or do i need different components to solve the issues? Thanks for the input, as it is "down" now and driving me batty

as far as the clearance issues are concerned, i have found that placing a blob of play-dough on the highest point of the air cleaner and closing the hood tells me exactly how much extra room there is for the intake/carb/air cleaner stackup. however, this is w/o a hood blanket on the car.
also, i know that it may take more time to get the parts, if you use a online corvette parts distributor, you will save a lot of headaches in getting things to fit and perform properly.

Look on the head between spark plugs 1 & 3, commonly used by factory for the water temp. sensor.
I thought you might be using the 600 model 1850 at first which I put on someone's car w/ a vertical connection at manifold.
I have not used 4011 or 4010.
4011 is similar to 4010 so this that someone posted for 4010 may do it.

I cant help with your questions but I have a comment about that Holley, I used one of them a few years back on an el Camino that I had and although people told me "You're using "THAT CARB" " like it was inferior or something, it ran perfectly on my car I was very
happy with it , once I changed the choke over to an electric one. In fact I still have it along with a Edelbrock manifold I may just use when I get enough ambition to finish my Corvette project. Peace,,,,Moosie

Thanks. I found an online fittings place, as nobody stocks fittings locally anymore due to the rising cost of brass. I checked clearance this afternoon. Gonna need a low air cleaner!!! I just love projects that don't fall into place 
If the carb gives issues, I might look into the other model...

One other issue: EGR. The Edelbrock intake has a rectangular port with two threaded holes at opposite corners. The car has a 1/4 circle shaped EGR, much larger. I am trying find either an adapter, or the year/model that chevy used the rectangular style EGR. Which of course doesn't quite clear the carb,either...

For Performer RPM a drop base filter is needed.

Edelbrock performer 2101 does not have EGR mount but does have a choke tube mount shown in best 2101.
