American vs German classic? That is what you’re going to get in this video as a 1970 Corvette LT-1 goes head-to-head with a 1973 Porsche Carrera RS on the Gateway International Raceway. Both cars were considered monsters during their days as they are capable of going from 0-60 mph in 5.7 seconds. The major difference between the two though is the top speed. The Corvette tops at 120 mph while the Porsche can reach 152 mph.
