Galli won the Circuit of Mugello race in 1968 and was second in the Targa Florio (with Ignazio Giunti). In the 1968 24 Hours of Le Mans, he finished 4th in an Alfa Romeo T33/2. The following year at Le Mans, he finished 7th in a Matra. In 1970, both Alfa Romeo T33/3 did not finish.

He moved briefly into Formula One in 1970, debuting in the 1970 Italian Grand Prix with a McLaren-Alfa, and had a handful of drives over the next couple of years, finishing 3rd in the non-championship Grand Prix of the Italian Republic at Vallelunga in 1972 for the small Tecno team.

His one shot at the big time came that year when he drove for Ferrari in the 1972 French Grand Prix at Circuit Charade near Clermont-Ferrand but he made no impression, finishing only 13th. After half a dozen outings for Frank Williams the following year, he announced his retirement.

Galli participated in 20 World Championship grands prix in total, scoring no championship points.
