Clearance

Yeah i was just wondering how much clearance is under my 84 Z28 hood, to add a new intake manifold and/or new air cleaner. My buddy told me theres no way i can add any of that without getting a new hood.

Depends on the manifold. A standard Performer intake will fit no problem. A Performer RPM is tight, but it'll fit with proper air cleaner selection.

I had a Performer (with poly motor mounts if that makes a difference) on my old LG4, along with a dual snorkel. The fit was close enough that the imprint of the air box could be seen in the underhood insulation.

Off topic: Z28er, what Holley? How'd you modify? What you do for an air cleaner after modification?

I hate to even say it but your friend is an idiot. I hate people who can't think positive. [Though hating them is an oxymoron.] I just don't like when folks can't think outside the box. They assume everything is to hard to even try. Unless some fancy mag told them it works.

You know a "good friend" was standing there saying similar 1000s n 1000s of years ago when the wheel was being invented.

round rock dumb uga bouga

Though it should be obvious from now on, don't take or listen to advice from him.

Just about any will fit under your stock hood with a little positive thinking and work. There is always a way. But if your depending on your friends advice a CC and a summit catalog, think again.

Just take it slow and go one step at a time.

Here is just a quick one done as a cut away. Like ya see on show cars. Ya run everything low and on the sides. air filter slips down and around the carb.

Take a few tall pieces of clay and stick them to the top of your air cleaner. Then close the hood. The hood will smash down the clay, and you'll see exactly how much room you have to play with.

I kinda don't get the one pic.
Why have dual snorkles but have the lid spaced up like an open element filter???
