Pro racing returned to Meadowdale for the USRRC races in 1964. Ken Miles easily won the Manufacturer's race from teammate Bob Johnson. Chuck Stoddard's Alfa TZ beat the Lotus Cortinas of Dave Clark (no, not the Dave Clark 5 drummer) and Trevor Taylor.

Jim Hall was on the pole for the Drivers race and he qualified the sister car, to be driven by Roger Penske, with the third fastest time. Penske had to start from the back of the grid because he did not arrive at the circuit until Sunday morning. When the race started Ed Leslie, in the Shelby Cooper-Ford, got off the line first to lead the first lap from Bobby Unser and Hall. By the third lap Penske had moved from the back of the grid up to the lead Leslie, Unser and Hall. After 11 laps Leslie was out with a broken suspension. Hall took the lead, won by 40+ seconds from Penske and clinched the '64 championship.
