    Ok. So I've been searching the nets and I just can't seem to find what I'm after. I'm looking for a velocity stack for a 4 barrel, and I see jegs and speedway and all the rest sell the same 8 3/4 diameter one. I'm looking for one that's a little bigger, like maybe 12in or 14in. Oh and the style I'm after is the one with the mesh top, not a small air filter. I figured if anyone would know, the H.A.M.B. would know!

    You might try a heating and air supplier for reducers you could modify.
     
  3. You'd be surprised how air flows thru these when you open the bottom of one. Restaurant supply store.

    I have a couple of OLD aluminum "salad bowels" I picked up in a second hand store to make velocity stacks out of. I say old, because anything new these days, is plastic or thin stainless steel; plastic does't hold up, and it's hard to form stainless steel to fit a carburetor. The aluminum is fairly easy to work with, it's soft and easily shapes to fit the top of a carburetor, and they were CHEAP. Just don't raid your wife's kitchen for anything.

    Yup, not that easy to find, but you could potentially make one.

    Pic snagged from the net:

    The salad bowl was a dyno sensation as tested on Engine Masters show on Motor Trend On Demand. I think it really woke some people up on the way air prefers to flow into a carb. It was a great episode.

    the salad bowl did ok, but the normal velocity stack was better....

    think about what the air has to do to get into the carb, it makes sense. Air doesn't like to go around corners, it likes to go mostly straight. The normal velocity stack straightens it out. The salad bowl doesn't really.

  14. Man, I remember a friends Fairlane catching on fire with one of these breathers, the gas soaked foam element burst into flames and did a lot of damage to the hood, carburator and wires before he got the fire out, he was lucky someone came to his aid with a fire extinguisher. HRP

    yup, seen that. one good pop back through the carb :eek:
     
  16. Anything with that top is called "flying eye" motion, edelbrock or the modern velocity stack ones. I have a motion myself, that you can see sitting on the big block and a couple of the edelbrock's that are good for keeping stones out at the track. 20181008_235539.jpg 20181008_235959.jpg

    I was at a scrap metal yard and they had a bunch of industrial aluminum spot lights. The velocity stack came to my mind's eye back then. They were huge . Make your car look like one of those hot wheels cars of old.

    Anybody know where to get replacement foam for one of these air cleaners? Not sure what brand it is.

  21. Your best bet is to buy a K&N type lid and trim it to fit, or buy the 11 inch one and make a ring to take up the gap. 798272-3c929011848c0efc13172842310d198f.jpg
