First picture,This would be a replacement for the factory intake. Exactly the same but aluminum. I have it bolted on a plastic mock up engine in the second picture because its light and is the same dimensions as a factory cast iron intake. It has all the same hose and sending unit outlets and even the choke tub.
The LD340 would be the same but it does not have the choke tub built in.
Second intake choice A Wieand is another good intake seen in the third picture on the engine painted orange.
An Air gap seen on the forth and fifth picture we had to cut the hood braces for the factory air cleaner. seen in the forth picture
Sixth picture is a holley strip dominator. This also needs hood trim for the factory air cleaner.
You can get away with the taller intake if you use a low profile aftermarket air filter base. That is what we use to make the air cleaner on the seventh and eighth pictures for the Indy intake which is the highest . And it still sealed tight against the hood after trimming the braces.
Last picture is another Air Gap on a 67 Barracuda. It fit under the hood using the 69 and earlier air cleaner but tight. The car has steel motor mounts. If they were rubber it would bounce off the hood
