I'm gonna be runnin a cold air snorkel system on my 85 Monte Carlo's 406:

But I plan to run this on the salt flats...the eventual goal is 200 mph in a street-legal car.

If you're in an area wher things get pretty hot, ducting air from the outside and eliminating an open element air cleaner can increase horsepower. Will ya notice it with a little one barrel? I doubt it. But if you were ever to go to a 4-barrel carb and headers, you'd probably notice a difference when driving in hot weather.
