DeLorenzo, and was delivered to Hanley Dawson Chevrolet in Detroit. Hanley Dawson also supplied the young DeLorenzo with all the equipment and financial backing necessary to mount a full campaign in SCCA A Production racing.
The L88’s Racing Dominance
The L88 was a race car, and Chevrolet wanted to keep it on the track. Advertising for the car rated the L88 as having less horsepower than the cheaper L71 package, and Chevrolet released a figure of 430hp at 4600 rpm. This was well below the actual peak power, which fell between 550 and 600. The L88 instantly established its racing dominance, winning many races and setting multiple speed records.
