I have an 88' Firebird TBI 5.0
A guy on my third generation F-body forum told me I could take the air filter out of my air cleaner(which is round) and put a taller filter in. He said I should flip over the cover, and tighten it upside down, so about 1 inch of the air filter is still visible. He said it gave him better acceleration. Is that safe?

The air cleaner assy is also a spark arrester. This impedes some of the effectiveness of that. It also makes for a loader cool noise of the carb sucking in fuel and air which makes it sound impressive but not legal as that is considered noise pollution.
I could be of marginal help for plain HP but defeats the Thermac system to atomize fuel faster when cold hence uses more fuel.
Also prohibits the induction of air from preferred locations extending air filter life. HO, HP vehicles from factory have used dual snorkels to assist in this.
The quality and condition of the air filter is of primal importance and keeping that in top shape will always help.
In short: It can help for just plain HP with side effects. Marine engines don't bother with with air filters at all but instead use an all metal 360 degree spark arrestor as road dirt is not a problem with marine use (same basic engines are used) and more power and less complication is always nice for that use. Those spark arrestors will stop large particles but are not an air filter.
This would not be legal where I live as if anyone pays attention. Marginal for performance but does make an impressive roar. I equate that to putting baseball cards in the spokes of a bicycle to make it sound cool which of course does nothing for the bicycle. Ram air does help when vehicle is at speed at the real force of air going into your engine is only the force of atmospheric pressure and when you trap and ram the air you effectively increase the atmospheric pressure.
Note: The density of the incoming air is important and for real. Performance and max HP will be at sea level or lower when atmospheric pressure is is higher than average which occurs on cloudless days.
Probably more than you wanted to know....
