Hello All, On occasion while living in California I would make a run north and south to visit family,usually distances of 225 0r more one way,I would "pop" the hood of the Vette enough that air would pass through the engine and out of the tight compartment and reduced the amount of heat collected in the engine bay. I would cruise at 80 -90 mph and the hood stayed where it laid on the the locks and engine temp stayed at 190 degrees.When I got to where I was going to be for a while I opened the hood and allow the engine to breath..Still do this here in Florida,however the runs are shorter and slower..

I am just curious. Does your ride have the factory air cleaner with all components connected and functioning as designed??? My 1977 L82 is completely original and I live in the south. Have had no instances of "carb boiling."
Here's an under the hood picture.

To answer the question of whether or not I have the stock air cleaner etc. on my car the picture above this is the answer.I only have use the stock cowling and made the Stainless steel plate to direct the air to assist in cooling as oppose to the two (in my engine) snorkels normally of '80 Vette engines.Sorry to taken two spaces up with the answer,however could not add text to the last reply.Have a great day.

I have been wondering about owners who are experiencing carb boiling and whether they have removed the engineered air cleaner system that was on the car new.
With a cleaner such as yours, the engine is breathing hot air. Cold air is more dense and is always a better option for any combustion engine. That is why superchargers have a cooler to make sure that the engine is getting the dense air.
Also, the after market air cleaner is not acting as a heat sink for the carburetor. It does not have enough mass. And the original set up had scoops that routed air from outside the engine compartment (cooler air) into the throat of the carb.
There were no snorkles on the LT-1s. I've noticed that if my car sits after a drive, when I start it up, the engine won't rev on one push of the gas pedal. Kinda have to goose it a few times. Then after a minute or so, it runs normal. It's as if the ethanol in the gas causes the gas in the hot lines to boil or something.
