I don’t know anyone who did that. We all had legitimate hot rods, not flipped lids. Really?
Here’s a pic of my ‘66 mustang, back in the 70’s. It’s dirty, but it’s a runner.  Why would you do something that doesn’t make your car any faster? You want cool sounds? How about those long tube headers, Shelby intake and a nice carburetor? That is the way. Same car today.

Also, it wasn't my car and it had to be returned to my parents in fairly unmolested condition. Dad wouldn't have liked headers and a Holley on his Grand Ville. He bitched after the shop knocked the innards out of the cats on mom's duece and a quarter (455 w/TH400) as a cheap fix when they clogged up. As a teen, I thought it sounded great. I am impresssed that you managed to hold on to a car you've had since the 70s, and a cool one at that. Best I can do is my 76 F100 SB owned since 1986. Wish that I could have kept more of them, but shit happens. |

Mine wouldn’t fit flipped after the NOS spacer went under the carb. Never hit the nitrous. Was pushing it pretty hard prior and never got around to getting everything good enough. I miss the sound and the car. But also not really. My Toyotas are so much better made and I’ve never felt the need to pop the hood and tweak the mixture at a red light.

Quote HistoryQuoted: I did that especially with a 4 barrel carb Hell yeah. That 4 barrel sounded MUCH better when you were in it. Your engine also breathed better. The under hood air was the same whether it was flipped on not, hot under hood air either way. Now for a REAL performance increase you needed the yellow plug wires.

I had a few colors with yellow included. Bought a few diy kits and MSD were my favorite. Spent hours cutting them to the perfect length and can’t even remember what color they were. Red and gray maybe? Changed and even indexed plugs after a few months. Just changed them at 125k and not sure if it was worth it on my old Toyota. |

Quote HistoryQuoted: Nothing sounded quite like a Rochester Quadra Bog as the secondaries opened, the whooooose. When I got that 81 Z28 with the cowl induction hood/scoop I remember sitting at stop lights, popping the pedal down just enough to hear that thing start to suck air in from right in front of me. I spent several months getting over the thrill of hearing that sound when I pushed the pedal down and wound that 350 up (the 305/T10 had been replaced with a 350/Muncie.) |

When I was just learning to drive my mom had a 69 Impala with a 350 and 4 barrel carb.
Used to drive it some even before I was legal age. Not sure where I learned the trick of flipping the breather lid but I absolutely loved the sound it made when you would stomp on it and the 4 barrel would kick in.

As a kid I knew very little about cars and I had an absolutely terrible (but cool looking) 1968 Mustang convertible. I bought some (probably crap) aftermarket chrome air cleaner for it. It looked super cool and I was really pumped up about it. Until I shut the hood and punched a nice dent into it because my fancy new chrome air cleaner was too tall Oh well, the only people who never made mistakes are the ones who never did anything. A kid has to learn somehow. Edit to add: I knew so little about cars that I didn't even know about flipping the lid back in those days. |

Lol that brought back a memory.
My first car was mom and dad’s old ‘73 Olds Cutlass 4dr with a 350 Olds. Within the first month, I had flipped the lid for shits n giggles. I had saved up enough at my gas jockey job to get a proper tune up so took it in to an old family friend who ran an old school original GM garage in a nearby town. When I got the service invoice, one of the notes was: “air cleaner lid was inverted, not recommended doing so in the future.” With nothing but dusty gravel roads all around, I suppose he did have a point. |
