1973 started Corvette's transformation from muscle to touring sports car. A Chevrolet advertisement headlined: "We gave it radial, a quieter ride, guard beams and a nose job." Indeed, redesigned body mounts and radial tires did improve Corvette's ride, and interior sound levels were reduced by 40%. The chrome rear bumper was essentially carried over from the previous year. However, the chrome blade front bumper was dropped for the federally required 5 mph (8.0 km/h) standard for a light-weight front bumper system with an inner transverse tube attached to the frame with two Omark-bolts (special steel fasteners which absorbed energy when a forming die, pushed back by the bumper, was forced down their length), and an injection-molded urethane bumper cover. The urethane nose was chosen over Chevy's other alternative, a more protruding version of the previous metal bumper. The new urethane bumper assembly added thirty-five pounds to the fron end. Two 350 cu in (5.7 L) small block engines were available. The base L-48 engine produced 190 hp (142 kW). The L-82 was introduced as the optional high performance small-block engine ( replacing the LT-1) and delivered 250 hp (186 kW). The new hydraulic lifter motor featured a forged steel crankshaft, running in a four-bolt main block, with special rods, impact extruded pistons, a higher lift camshaft, mated to special heads with larger calves running at a higher 9:1 compression, and included finned aluminum valve covers to help dissipate heat. The L-82 was designed to come on strong at higher RPM and ordered with nearly 20% of the cars at a cost of $299.

This car came in needing just a little work done. Some of the things that need to be fixed is the headlights, a buzzing noise, steering column and shifter linkage.
Started tearing down the steering column to see what the problem is.
Our technician found the problem, the tilt mechanism was lose in the column so he tightened up.
