Yeah ~ I'm a DB6 man but would take any of them. Carrozzeria Touring of Milan did a fine job of the DB 4, 5, & 6 for them with some local fiddling, William Towns, to a great degree followed it with the squared up V8. Hard to miss an Aston. That Grill.

I agree the closed front V8 scoop doesn't work. They could have learnt from the E type there. Isn't the front of the DB4/5/6 bulge necessary to clear the front of the cam covers, over the timing chains? Either way, they're all lovely cars. As you wrote the DB4GT, probably my favourite for looks, was moving towards Jaguar. The Zagato tried to get closer, but missed. Still, it has an appeal that I can't help but like.

I'll measure next time I stick my nose under her ladyship's car's nose. I thought it cleared ~ just. There is a labyrinth arrangement that ensures no water gets into the engine compartment. The carbs fit into a boxy plenum in the fender and you can see the aircleaner that the scoop feeds to the front. You need to orientate yourself to understand the flow. And look at all angles on the bonnet frame & hole. It's subtle. Webber & SU pretty much the same.
Airflow in red. The fan is shrouded from the inlet. Note inner bonnet in the inlet is not equidistant with the outer body. It "squeezes" the air toward the the aircleaner in the right front corner, plus channel.
The engine compartment has more side room than a Mk2.
As you know there were many Series of the DB4 prior to '5 & '6
BTW. I would not rate it a cold air intake. It tries to be & is semi successful.

Idea platform for hood scoop. A not so good bonnet/hood is being sacrificed for this project. I had it blasted to remove hmmm maybe six different colors, and the center rib was 80% gone.
The "eye" bolts represent the high points to allow 1" clearance above the air cleaner. Center three are 2 3/8" high. The front two outside eye bolts are 2 1/8" high. The rear yellow line locations are 18" apart, and the front locations are 14" apart. The design would somewhat rounded like an "e" type or some of the Aston Martin models Glyn shared.
Comments welcomed.

Primaz & all,
So this the look at another possibility. Most previous posts the the cut up hood idea was a no go. At this point, I pretty much agree. This possibility is maybe 2" shorter in height and a minimum width, so not as wide or tall as a cut up hood.
It's more about a nasty loud engine than the hood anyway. It's equipped with FlowMaster's loudest street mufflers - Super 44's. Not cutting the air filter height. There's a one inch carb spacer, it stays. It was dyno'd with it. The carb is a 980 CFM. The engine is not in flexible mounts, but I'm allowing for any movement and trying not to choke the air off from the carb. There is a one inch side clearance also. I'm still toying with cowl induction, but don't like weather exposure. Not that I expect the car to see much rain.
I have a scoop builder coming in next. I'm sure there will be a couple of other ideas.
Keep the comments coming.

Looking at this earlier pic Clyde, that air cleaner center point is awfully high. Is there any way you can modify - even leaving the element alone but recessing the black flange and nut to be flush - that should be worth 1/2" or more? And 1/4" or 1/2" should be plenty of top clearance with solid mounts? A level line from the cowl to the leading edge of the air cleaner looks like it might make for an attractive scoop. Good luck and keep us posted.

Doug,
Thanks for the comments. The nut is a nyloc, but the stud can be shortened by 2 1/2 threads, maybe more with a thin nut nyloc.
Motor mounts are urethane bushings. There will be some compression on load, but I don't know how much.
I like your idea of scoop, rather than cowl. I'll mock that up.

Clyde, If you can, I think the curved DB4 that Glyn matches better as this scoop looks to me a bit to rectangular with sharp lines like something on a newer Camaro, etc.. I think a more subtle curve shape and since the height does not need to be very tall, the more it matches the round curves of the car the better. I think a decent body shop or metal fabricator could copy the design of the DB4 but make it even a little lower in height as I do not think your car requires it to be has high, which would make it look better than the DB4 in my opinion.

Clyde. Whatever you do you are going to blend the scoop into the hood.
With Jag curves I would go somewhere near the DB4GT short chassis,
It's your car and with a good metal worker you can pretty much shape it in as you prefer. Do you know anybody with an English wheel that can roll an off the shelf unit to your liking?. e.g. flatten the DB4GT a little.

The other way is to just use clay or foam and shave it to the shape you want and use fiberglass to make a mold. I do not think you are going to find that classic DB4 hood scoop or anything premade and even if you could you do not need it as tall. Thus I would go down the fabrication route either with a metal fab or a good fiberglass/body shop as the design is not that complicated.
Here is an el cheap way with no mold
another cheap way to use foam
