On my '73, I'm running the Holley Contender 300-36. It's the aftermarket version of the early 70s LT-1 high rise intake. I'm running a Holley Street Avenger carb, Holley heat shield, 3" air filter element, 1.5" drop base air cleaner, and a flat billet air cleaner lid. The lid is approximately 1/4" thick above the air filter. The **** that secures the air cleaner lid sticks up about 1/4" above the air cleaner and I have about 1/2" clearance from that **** to the hood.
The outside edge of the air cleaner lid in one spot toward the AC compressor just barely touches the inner hood at times. I can see rub marks. To solve this, I either need a different air cleaner lid that is less than 1/4" thick at the edges and doesn't rise much in the middle, or I need to replace the 5/16" carb gasket that came with the heat shield with a slightly smaller (maybe 1/4") gasket.
This setup barely clears the choke plate on the carb. I'd rather have more space between the air cleaner lid and top of the carb but that's as good as I can get with this setup. All in all, it's a tight fit but it runs well. My future plans include EFI and I'll look at different setups then.
