The 355-A, eight cylinder, was similar to the Series 353 of 1930 except the body was longer and lower. The hood was also longer with five hood ports or rectangular doors. The cowls had matching doors. the coach sill was modified and there were no compartments in the splash pan. The battery and tool compartments were located under the front seat. The floor boards were metal. The instrument panel was oval with the same grouping as the Series 353. It also featured a radiator screen, single bar bumper, and dual horns. The headlight diameter was reduced one inch.

The frame was new with divergent side rails. The rear springs were mounted directly under the frame rails. There were metal covers on the springs. The radiator was mounted lower in the frame. The cooling system contained a condenser tank.

The engine displacement was the same as the Series 353, but the series designation on the V-8 models no longer matched the displacement. The V-8 now had a five point engine suspension similar to the V-16. An intake muffler was added. The distributor was 38mm higher than on the 345. The fan was mounted lower to match the lower mounted radiator.
