220HP Air Cleaner

[Alex V.]

After examining what I believe to be my '67 'Burb's original air cleaner, I'm puzzled as to why Chevy put such a small-mouthed air cleaner on a 4-barrel carburetor that would, seemingly, nearly meet if not exceed the flow capacity of the air cleaner snorkel. I know the 220 horse top end isn't high-flow by a long shot, so is the snorkel size just deceiving or is it a tight point in the induction system? Assuming my air cleaner hasn't been swapped somewhere along the way. The snorkel mouth can't be much more than 1 1/2" dia.

Is yours anything like the one in the picture below? It's original to my 69 3/4 ton with 350.

Not sure but I bet it flows about as well as the factory single exhaust....

We just used to flip the top cover over so we could hear the BAAA WHAAAAAAA engine sounds when you stomp on the old quadrajets ,Still one of my favorite sounds and carbs .

Firstowner69, the snorkel looks similar in size, but the housing is taller. Here's a pic:


Dad had full dual 2"? exhaust installed back in about '99 so I don't have to worry about that. Yeah, I'm familiar with that sound from a friend's '73 Cadillac and my '85 C3500. One time, merging onto I-64 East out of St. Louis with 9,000 lbs. behind me, I tipped into the truck just right and heard that muffled leaf blower noise roaring under the hood - through that big, closed, spark arrestor air cleaner with the windows rolled up!

That's the same one on my 1967 327 220 hp . Grumpy old man , same here I'll never forget the sound of that four barrel kicking in. Even if I was only twelve behind the wheel when it first started........sssshhhh mom was sleeping.

Okay. I was pretty certain it was. I wouldn't think the air needs for the current engine is much different than the 220HP, but might I be wrong? Current setup is the stock 220HP carb./intake on a >9:1 comp. 350 w/1.94 "624" heads and a Goodwrench 290HP cam.
