Here is a list of what fits height wise. With stock low profile air cleaners.
The LT-1 is a bit too tight on a 72 stock hood. But a 77 does have a little more room.
I can not help you with the oil fill though.
Maybe the old C2 L76 intake?
IIR does it have an oil fill tube?

Here is an Intake from Edelbrock that not only has the hole for an oil fill but comes with the chrome tube and cap also.
Eddy 2703 around $325
However, you will have to go to Eddy web site and check the carb pad height on that model.
I will warn you that about every SBC Intake they sell has a asterisk* *Will Not Fit Under Corvette Hood. This is a liability thing so as not to get Intakes returned for a refund.
There should be another asterisk* that says, yes it will if you know how to do it.

Great chart! Thanks for sharing. Saving that one in my “‘Vette stuff” files!!!

Great find!
It's another version of the EPS with an oil fill tube.
And it has a 4.2" pad height, so it is in the will fit range.
A 100% stock intake & air cleaner setup on a 72 gives you 3/4-1.0" of hood clearance.
With a 3.5" intake. A 4.2" does fit but starts to get tight.
Stock style drop air cleaners must be used.
A 4.5" does not fit.
But on 73-78 has a little more hood room due to the scoop.
No one has been able to say exactly how much.

I ordered the Blueprint 350 ci 390 hp long block.
Have a set of SS side pipes from High Flo and we have a set of original GM aluminum side pipe covers.
I just did a clay check on a stone stock 74 with the stock domed hood, air cleaner, etc. including .25" thick carb gasket.
It had 1-5/8" air cleaner to hood clearance as stock.
They have 1-1/8" more hood clearance than a 72 std hood does.
So even a 4.75" pad ht RPM air gap could be made to fit.

All this reseach I went with the Blueprint low profile. They claimed it to be a clone of the zz4. It's not going to work for oil service, there is no safe way to cut a hole without hitting a water passage.
It looks like the 3 Edelbrock performers (2101,2104 or EPS) or an LT-1 will fit the bill for adding oil, do any of these fit a Quadrajet?
Can't help you with your oil situation but I just installed a Weiand 7530WND single plane Team-G intake on my ZZ4 and it fits under my 1971 base model stock hood. And no, I don't feel any loss of low end torque from my butt dyno going from a dual plane to single plane.
Hood clearance check. Have plenty of room except for the passenger side which is close at 1/4" or so:

As well you shouldn't with EFI. Keep it real, dual planes are for carburetors.
