Chevrolet 283 c.i.
The 283/283hp fuel-injected engine was among the first of the American engines to offer 1 horsepower per cubic inch of displacement. Under legendary Corvette engineer Zora Arkus-Duntov's supervision and encouragement, a robust supply of factory and aftermarket parts were ultimately developed for the 283c.i..
Even after the 327's debut, the 283c.i. made such a good base that it soldiered on through the 1960s. With its short 3-inch stroke, the 283c.i. can offer great performance, but the smaller bore size did have limitations.
