When you add up the additional height of the 4500 carb (4150 is shorter), raised/extended intake ports and a reversion spacer/nitrous plate/etc. You run out of room under a 6 pack, hemi or 023 scoop. A 6" scoop is no problem depending in the intake/spacers/etc.

For instance, the early 70s DC tunnel ram scoop does not come close to clearing our 511" Indy -13 low deck that has an Indy t-ram (4500) topped with QF 1050-AN carbs using HVH adapters with no filter or velocity stack. You run out of hood/scoop clearance quickly with all of these hotrod parts. I design my jnduction systems with a 14x4" filter minimum with 1.5" drop base max. So far no strange issued with AFR readings which leads me to believe the fuel curve is stable.
 
Yes that is a trick flow intake. I have a indy low deck 4500 now. Here is the cam specs in the picture.

Is this set up in one of your chargers or the dart ?
I was going to purchase a scoop from a good member on here and figured I will also be about 1 inch below the top of a super stock scoop.
If I wasn't running 2 inch merge spacers on my tunnel ram I probably could run that scoop but I am leaning towards a early 70s pro-stock scoop to tie into the entire goal of the car.

GTS is a low deck with 440 source heads, M1, 1/2" plate, 1.5" drop base 14x4" filter. Scoop is a 6 pack. Thumperized 4150 QF 1050 down leg carb

Red 66 Charger wears a WO23 scoop over the 511" MW victor headed motor with an Indy 4150 low deck intake topped with a Holley 4150 EFI throttle body and 1/2" plate.

Black 66 Charger wears an extended early 70s PS scoop. It is similar being a low deck 499" (4.150 stroke) however it has Indy -13 heads, Indy t-ram and the adapters/carbs listed above. I think you will need to make your scoop taller to run air filters.
Air filters are a good thing out here in the land of lava dust. I tuned a car with no filter and it was suprising how nasty the carb was after a few races.

Nice × 3 and thanks for the advice.
My blp got pretty nasty from just running on a Dyno so yeah I'm definitely going to figure out and probably make a sealed filter housing.
I'm going to try and remember how to glass parts again this winter and see if I can duplicate a ps hood scoop (taller)

If you need to take a mold I have a PS scoop kicking around.

I run a 800 Edelbrock AVS on my 499 RB. I wouldn't get to hung up on carb size. An engine pulls what air it wants or can get through whatever size holes you mount on top.

If you want a crisp throttle I would forgo the big carbs for your combination, but everyone finds that out in time.
