With stricter emissions controls in force, the compression ratios on all Corvette engines dropped for 1971. The base 350 now plugged along with 270 hp, the LT-1 350 dropped to 330 hp and the detuned LS5 454 now made a mere 365 hp. Gone was the LS7 454 and in its place was an “LS6” 454 four-barrel V8 rated at 425 hp. Those are still heady numbers, but the diminution of Corvette performance would continue throughout the rest of the decade. Except for the power losses, the ’71 was essentially the same as the ’70.
The power drain would continue for 1972 and was exaggerated by a switch from SAE gross to SAE net power ratings. So the base 350 now carried a measly 200-hp rating, the LT1 made just 255 hp, and the sole big-block, an LS5 454, could only muster 270 hp. About 30 ’72 Corvettes were powered by a special “ZR-1” version of the LT-1 350 as part of a club-racing package.
A body-colored rubberized front bumper took up residence on the 1973 Corvette, replacing the chrome strip used previously. Furthermore, the side vents were now single, almost vertical, openings and radial tires were standard for the first time. Power dropped again, with the base 350 now rated at 190 hp and a new optional “L-82” 350 making 250 hp. The sole 454 was an “LS4” rated at 275 hp.
