According to these:

They are identical in height unless I'm missing something?

Nope you are on the money ( and I crossed my words ). The RPM series whether its an AirGap or not seems to be 4.72" in height

Performer Air-Gap # 2601 or 2604* is 4.32" ( its not part of the RPM lineup and slightly shorter )
* they show the 2604 is for 87+ blocks

^^ this is what a friend is running on his MCSS with stock air cleaner and hood insulation, all black to match his crate motor


Or you can get even lower with or without EGR with the original performer intake 2101 or 3701 series at 4.05"

Got a pic of this by chance?

So would the Performer Air Gap (2601) work well on both a stock 305 and basic chevy 350? Or is the MC alum intake that lilbowtie suggested perhaps a better add on for both the 305 and 350 later on?

Any aftermarket intake is likely better than the aluminum MC SS one. Even for a 305, you want the best flowing intake possible. IT is best to stick with a dual-plane to maintain low-RPM torque/idle quality for the street. So, with that in mind, it would be best to pick the best performing dual-plane intake that still fits under your hood and works with the carb you are using.

According to pontiacgp, the Performer RPM you are looking at should fit under the stock hood even with a spacer (which you will need if you decide to not use the quadrajet). It also should perform well on a 350. I think that if you can get for a $100 or so it would be a great deal.

Drogg- I will have to go looking on my old phone as its been at least 2-3 years since I seen the car. Life took over and it sits patiently waiting in the corner of his garage. I got the gmpp intake on my car when he switched over to the Air Gap

OP- 2601 will work if you want to retain the qjet and factory air cleaner. Otherwise grab the RPM and get a drop base air cleaner. Its your car, build it like you want. Either way they are drilled for both bolt patterns to run the carb you like

Luke - you got a lot of info and you should investigate this yourself. You need to consider what you are using your car for and the RPM you will be operating at. Look at the HP gains intakes claim and where that RPM is. Your after market intakes don't have heat shields so you might be better off with an air gap style. I had a 1979(350 w/ 3.73's) van I towed with, installed headers(improvement) then I installed an Edelbrock performer and lost bottom end couldn't pull hills, would boil the carb, and lost 1.7 mi's/ gal - put the original back on.

Had a performer rpm on a stock 305 with headers and 600cfm edelbrock with a 1" 4 hole carb spacer in my 83 c10, and that was one of the best running engines I ever owned. I say go for it, it's still way better than stock.
