use of a decent quality air filter will significantly reduce engine wear in most environments, as it prevents a great deal of outside dust and grit from entering the engine, and getting introduced to moving components, the standard muscle car air filter was about a 14" diam and 2" -2.5" tall filter similar to this one
in a box similar to this one
but many guys found the more open look like this preferable
swapping to a 3" filter element if you had the required hood clearance generally resulted in a bit less restriction and a bit more horsepower
COOLER AIR is denser and contains a bit more oxygen and tends to reduce the tendency to detonate with marginal octane fue so routing outside air thru larger duct-work and limiting the hot engine compartment air from being inducted to the engine tends to help hp/tq
