PIATOGEL Engines for the 1975 Chevrolet Chevelle Malibu lineup ranged from the standard 250-cubic-inch six and 350-cubic-inch V-8 to V-8 options of 400- and 454-cubic-inch size, the last with a 235-horsepower rating. Base engine was a 250-cubic-inch six, but Chevelles might have any of four V-8s: 145-horsepower 350-cubic-inch, 160-horsepower 350 (with four-barrel carburetion), 180-horsepower 400, or the big-block 454 rated at 235 horses. Sales skidded again for 1953, thudding at 28,000. First, Kaiser still had only an anemic six to counter the potent overhead-valve V-8s of most rivals.
