A Duesenberg SJ-525 Riviera Convertible Sedan of 1934 with Lycoming engine. Lycoming still manufactures engines but only for small aircraft. The straight eight model J motor was based on the company’s successful racing engines of the 1920s and though designed by Duesenberg they were manufactured by Lycoming. In unsupercharged form, it produced an impressive (for the period) 265 horsepower (198 kW)from dual overhead camshafts and four valves per cylinder. It was capable of a top speed of 119 mph (192 km/h), and 94 mph (151 km/h) in 2nd gear. Other cars featured a bigger engine but none of them surpassed its power. (Technical information from wikipedia). Due to their high speeds the Duesenberg cars become favorites of gangsters.
